The Color of Mars is Bright Red

 Mars is known as the Red Planet, but its actual colour up close is more of a butterscotch or dusty brown. 

Venus and Earth Twins

 Venus is often called Earth’s sister due to its size and structure. But living there would be impossible due to its sulfuric acid clouds, high carbon dioxide levels, extreme pressure, and high temperatures.

The Sun is Burning

 The Sun isn’t burning. It glows due to nuclear reactions, not combustion.

The Sun is Yellow

The Sun appears yellow from Earth because of our atmosphere, but its true color is white. 

Earth Closer to the Sun in Summer 

We have different seasons not because of Earth’s distance from the Sun. In fact, the distance varies slightly throughout the year but doesn’t cause seasons.  Seasons change due to the tilt of the Earth’s axis.

The Other Side of the Moon is Always Dark

The Moon’s other side isn’t always dark. The misconception comes from the fact that the same side of the Moon always faces Earth. The far side of the Moon receives just as much sunlight as the side facing us.

There are many Sound in Space

Space movies often include sound effects in space battles, but in reality, space is a vacuum where sound can’t travel. Only some sounds can be “heard” in space by instruments that capture electromagnetic vibrations and convert them to sounds that humans can hear.

Shooting Stars are Stars

“Shooting stars” are not stars at all, but meteors burning up as they enter Earth’s atmosphere.

It’s Impossible to Travel in the Asteroid Belt

Contrary to “Star Wars,” flying through the asteroid belt isn’t as dangerous as depicted because the objects are far apart. Space probes have passed through it without damage.

The Great Wall of China is Visible from Space

 The idea that the Great Wall can be seen from space is a myth. Even from a low Earth orbit, spotting it is challenging.

US Has Enormous Space Budget

The belief that a quarter of the US budget is spent on space technology is false. NASA’s budget is a small fraction of the federal budget, peaking at 4.41% during the space race in 1966.

Black Holes are Cosmic Vacuums 

People often think of black holes as cosmic vacuums that suck in everything around them. In reality, black holes exert gravitational pull like other objects. Their gravity doesn’t reach out to pull things in from a distance unless those objects come very close.

Asteroids and Meteoroids are the Same

Asteroids are rocky bodies that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter. Meteoroids are smaller rocks or particles in space. When meteoroids enter Earth’s atmosphere and burn up, they’re called meteors. If they hit the ground, they’re meteorites.

The Sun is a Unique Star

The Sun is often thought of as an exceptional star, but it’s actually quite average in size, temperature, and colour compared to other stars in the universe.

Space is Close to Earth

The idea that space is just a short journey above Earth is misleading. The Kármán line, the boundary considered the start of space, is about 100 kilometres (62 miles) above sea level, but reaching and staying in orbit requires much more distance and speed.

Mercury is the Hottest Planet

Because it’s closest to the Sun, people assume Mercury is the hottest planet. However, Venus, with its thick atmosphere trapping heat, holds this title.

The Moon Has No Atmosphere

The Moon’s atmosphere exists but it is extremely thin compared to Earth’s.

Humans Explode in Space Without a Suit

Humans wouldn’t explode in space; the lack of atmospheric pressure could cause harm, but the body wouldn’t explode. Immediate dangers include suffocation and decompression.

All of Space is Extremely Cold

Space is often associated with extreme cold, but temperatures in space can vary widely. Objects in direct sunlight get very hot, while those in shadow become extremely cold.

The North Star is the Brightest in the Sky

 Polaris (the North Star) is far from the brightest star in the night sky. That title goes to Sirius, also known as the Dog Star.

Neptune Appears Blue Because of the Water

 Neptune’s bright blue colour is not due to water but to methane in its atmosphere, which absorbs red light and reflects blue light.

Zero Gravity Means No Gravity

The term “zero gravity” is misleading. Astronauts in orbit are not experiencing zero gravity but are in free fall. They are continuously falling towards Earth but missing it because of their horizontal velocity.

Satellite Internet

Even people in the most remote areas today have access to high-speed internet. Satellite internet allows them to learn, work, and have fun. The demand for satellite internet has seen particularly significant growth during the pandemic when people had to stay in self-isolation.

You could stay at home and still chat with relatives, enjoy meeting in online pubs, or try a secure online casino.

Today Starlink aims to provide internet coverage to rural regions, islands, and developing countries. The low Earth orbit of the satellites helps reduce latency (the time delay in data transmission) compared to traditional geostationary satellites. Starlink has been developed by SpaceX, the aerospace company founded by Elon Musk. 

 Fast GPS Navigator

Asking artificial intelligence to find the way to any point in a city or world and to build the optimal route now seems like such a basic task that it’s hard to imagine life without it. However, without the competition between countries in space, people might still travel with paper maps.

The idea of a satellite navigation system emerged in the late ’50s in the United States. American scientists noticed that the frequency of the radio signal varied with the satellite’s position in the sky. It increased as the object approached and decreased as it moved away. At that moment, it became clear that with this technology scientists could calculate the speed and coordinates of an object on Earth, and vice versa. Thus began the development of the GPS Navigator. Now, anyone can use a satellite navigation system. It is built into smartphones, smartwatches, tablets, laptops, and other devices.

Solar Panels

Solar panels are made up of many silicon cells. These solar cells use the photovoltaic effect to convert sunlight into electrical energy.  When sunlight strikes the solar cells, they generate an electric current through the photovoltaic effect.  Solar energy is a clean, renewable resource that reduces greenhouse gas emissions and our dependence on fossil fuels. Besides,  solar panels significantly reduce electricity bills over time. They do not cost much today and require minimal maintenance. The principle of converting light into electricity has been known since the 19th century. Still, the development and widespread adoption of solar panels have been significantly accelerated by space exploration.

Satellite TV

The history of satellite television began on July 10, 1962, when NASA launched the first communications satellite, Telstar-1, into orbit. The next day, it enabled the first satellite broadcast in the United States. Telstar-1 orbited in an elliptical path and provided a continuous signal for 20 minutes during each orbit around the planet. It could handle either one TV broadcast or 60 phone calls.

Today, you can catch the signal almost anywhere; all you need is a dish-shaped type of parabolic antenna. It captures a signal from space, converts it, and sends it to a satellite receiver, which decodes it into picture and sound. The unique shape of the satellite antenna wasn’t designed merely for aesthetics. The round shape helps to capture signals from different angles and directions

Wireless Devices

Car vacuum cleaners, blenders, drills, and other battery-powered equipment share a lineage with spacecraft. Their history traces back to 1961 when NASA approached Black & Decker with an unusual request. For the lunar expedition, astronauts required tools that could function independently of a network connection. While battery-powered devices existed, they were not suited for space. After extensive testing, Black & Decker developed a battery-powered rock drill capable of drilling and collecting lunar soil. This technology led to the creation of other projects that simplified life on Earth. For example,  space exploration has contributed to the development of wireless medical devices, such as telemetry systems for monitoring astronauts’ health. These systems have applications in healthcare for remote patient monitoring and telemedicine.

As you can see, space exploration extends beyond scientific achievement and national prestige. It directly influences our daily lives, from blogging to family gatherings in front of the TV. In the future, we anticipate that Earth will benefit from additional technologies that will arise from further space exploration.

But there was no cause for panic then or now. The question was only about the decision of the International Astronomical Union which after long disputes deprived Pluto of the status of a full-fledged planet. And, contrary to misconceptions, the solar system did not shrink that day, but rather expanded unimaginably.

In a nutshell:

Pluto is too small for a planet. Some celestial bodies used to be thought of as asteroids, even though they are the same size, if not bigger, than Pluto. Both they and Pluto are now called dwarf planets.

The search for wanderers

The discovery of Pluto, long thought to be the ninth planet in the solar system, has a prehistory.

Before the advent of telescopes, mankind was aware of five celestial bodies called planets (translated from the Greek as “wanderers”): Mercury, Venus, Mars, Jupiter and Saturn. Within four centuries, two more major planets were discovered: Uranus and Neptune.

The discovery of Uranus is notable because it was made by an amateur music teacher, William Herschel. On March 13, 1781, he was surveying the sky and suddenly noticed a small yellow-green disk in Gemini’s constellation. At first Herschel thought he had discovered a comet, but observations by other astronomers confirmed that a real planet with a stable elliptical orbit had been discovered.

Herschel wanted to name the planet George after King George III. But the astronomical community decided that the name of any new planet should be consistent with others, that is derived from classical mythology. As a result, the planet was named Uranus after the ancient Greek god of heaven.

Observations of Uranus revealed an anomaly: the planet stubbornly refused to follow the laws of celestial mechanics, deviating from its calculated orbit. Twice astronomers calculated models of Uranus’ motion, correcting for the gravity of other planets, and twice it “cheated” them. It was then suggested that another planet beyond its orbit influenced Uranus.

On June 1, 1846, an article by the mathematician Urbain Leverrier appeared in the journal of the French Academy of Sciences, describing the expected position of the hypothetical celestial body. On the night of September 24, 1846, at his prompting, the German astronomers Johannes Halle and Heinrich d’Array, without much time to search, discovered the unknown object, which turned out to be a large planet and was named Neptune.

Planet X

The discovery of the seventh and eighth planets in just half a century has tripled the solar system’s boundaries. Uranus and Neptune had discovered satellites, which made it possible to accurately calculate the planets’ masses and their mutual gravitational influence. From this data, Urben Leverrier built the most accurate orbital model at the time. Once again, reality differed from the calculations! The new mystery inspired astronomers to search for a transneptunian object, which became known as Planet X.

The fame of the discoverer went to the young astronomer Clyde Tombaugh, who abandoned mathematical models and set about the hard study of the sky with a photographic refractor. On February 18, 1930, while comparing January plates, Tombaugh discovered the displacement of a faint star-shaped object – it turned out to be Pluto.

Astronomers soon discovered that Pluto is a very small planet, smaller than the Moon. And it clearly didn’t have enough mass to affect the movement of the massive Neptune. Clyde Tombaugh then embarked on a massive programme to find another ‘planet X’, but despite his best efforts, they could not find it.

We know far more about Pluto today than we did in the 1930s. Thanks to years of observations and orbiting telescopes, Pluto has an elongated orbit that tilts to the ecliptic plane (Earth’s orbit) at a significant angle of 17.1°. This unusual property has led to speculation as to whether Pluto is a native planet of the solar system or whether it is accidentally attracted by the Sun’s gravity (for example, this hypothesis is considered by Ivan Efremov in his novel The Andromeda Nebula).

Pluto has small satellites, many of which have been discovered recently. There are five in all: Charon (discovered in 1978), Hydra (2005), Nicta (2005), P4 (2011) and P5 (2012). The presence of such a complex system of satellites has suggested that Pluto has sparse debris rings – the kind that always occur when small bodies collide in orbits around planets.

Maps drawn from data from the Hubble Orbiting Telescope have shown that Pluto’s surface is not homogeneous. The part facing Charon contains mostly methane ice, while the opposite side contains more nitrogen and carbon monoxide ice. In late 2011, complex hydrocarbons were discovered on Pluto, leading scientists to speculate that simple life forms exist there. In addition, Pluto’s rarefied atmosphere of methane and nitrogen has markedly ‘swollen’ in recent years, meaning there is climate change on the planet.

What has Pluto been called

Pluto received its name on 24 March 1930. Astronomers voted on a shortlist containing the final three choices: Minerva, Cronus and Pluto.

The third option – the name of the ancient god of the realm of the dead, also known as Hades and Hades – proved the most suitable. Venetia Burney, an eleven-year-old schoolgirl from Oxford, suggested it. She was interested not only in astronomy, but also in classical mythology, and decided that the name Pluto suited the dark and cold world best. The name came up in conversation with her grandfather Falconer Maydan, who had read about the planet’s discovery in a magazine. He forwarded Venetia’s proposal to Professor Herbert Turner, who in turn telegraphed it to colleagues in the US. Venetia Byrne received a prize of five pounds sterling for her contribution to the history of astronomy.

Interestingly, Venetia lived to see Pluto lose its status as a planet. When asked about her attitude to this ‘demotion’ she replied: ‘At my age I don’t care about this kind of debate any more, but I would like Pluto to remain a planet’.

Edgeworth-Coiper Belt

By all accounts, Pluto is a normal planet, albeit small. So why have astronomers been so unfavourable to it?

The search for the hypothetical ‘planet X’ has been going on for decades and has led to many interesting discoveries. In 1992, a large cluster of small bodies resembling asteroids and comet nuclei was discovered beyond Neptune’s orbit. The existence of a belt of debris, left over from the formation of the solar system, had been predicted long before by Irish engineer Kenneth Edgeworth (in 1943) and US astronomer Gerard Kuiper (in 1951).

The first trans-Neptunian object belonging to the Kuiper Belt was discovered by astronomers David Jewett and Jane Lu, observing the sky with the latest technology. On August 30, 1992, they announced the discovery of QB1, named Smiley, after the character from the popular detective John Le Carré. However, the name was not used officially as there was already an asteroid called Smiley.

By 1995, seventeen more bodies had been discovered beyond Neptune’s orbit, eight of which were in Pluto’s orbit. By 1999, the total number of recorded objects in the Edgeworth-Coiper belt had passed the one hundred mark, and by now, over a thousand. Scientists believe that in the foreseeable future, will be able to identify more than seventy thousand (!) Objects larger than 100 km. It is known that all these bodies move along elliptical orbits, like the real planets, and a third of them have the same orbital period as that of Pluto (they are called “plutino” – “plutonchiki”). Objects of the belt are still very difficult to classify – we only know that they have a size of 100 to 1000 km and their surface is dark with a reddish tint, indicating the ancient composition and presence of organic compounds.

The confirmation of the Edgeworth-Coiper hypothesis alone could not have revolutionized astronomy. Yes, we now know that Pluto is not a lonely wanderer, but neighbouring bodies cannot compete with it in size, and besides, they have no atmosphere or satellites. The scientific world could go on sleeping in peace. And then the worst happened!

Goddess of discord

Mike Brown’s finest hour was on January 5, 2005 when his team discovered a transneptunian object estimated to be 3000 km across (later measurements gave a diameter of 2326 km). Thus, a celestial body was found in the Edgeworth-Coiper Belt, the size of which was definitely larger than Pluto. Scientists were buzzing: A tenth planet had finally been discovered!

Astronomers have given the new planet the unofficial name Xena, in honour of the heroine of the fantasy television series “Xena the Warrior Princess”. And when Xena’s satellite was discovered, it was immediately named Gabrielle, the name of Xena’s companion. The International Astronomical Union could not accept such “frivolous” names, so Xena was renamed Erida (Greek goddess of discord) and Gabrielle was renamed Dysnomia (Greek goddess of lawlessness).

Erida did indeed cause discord among astronomers. Logically, Xena-Erida should have been immediately recognized as the tenth planet, and the group of Michael Brown should be entered in the annals of history as its discoverers. But no such luck! Previous discoveries had suggested that dozens more objects comparable in size to Pluto might be lurking in the Edgeworth-Coiper Belt. Is it easier to multiply the number of planets by rewriting the astronomy textbooks every couple of years, or to scrap Pluto and with it all the newly discovered celestial bodies?

The verdict was handed down by Mike Brown himself, on March 31, 2005, when he discovered the object FY9, named Makemake (the creator-god of mankind in the mythology of the Rapa Nui, inhabitants of Easter Island), measuring 1500 km in diameter. When their colleagues ran out of patience, they convened at a conference of the International Astronomical Union in Prague to decide once and for all what a planet is.

Previously, a planet could be defined as a celestial body that orbits the Sun, is not a satellite of another planet and has enough mass to take on a spherical shape. Following the debate, astronomers added another requirement: that the body “clear” the vicinity of its orbit of bodies of comparable size. Pluto did not meet the latter requirement and was stripped of its planetary status.

It was moved to the list of “dwarf planets” (from the English “dwarf planet”, literally – “gnomic planet”) under the number 134340.

Such a decision has drawn criticism and ridicule. Scientist Alan Stern, who deals with Pluto, said that if this definition is applied to Earth, Mars, Jupiter and Neptune, which are found to have asteroids in their orbits, they too should be stripped of the title of planets. Besides, he said, less than 5% of astronomers voted for the ruling, so their opinion cannot be considered universal.

However, Mike Brown acknowledged the determination of the International Astronomical Union, satisfied that the debate was finally over to everyone’s satisfaction. And indeed – the storm has subsided, the astronomers have dispersed to their observatories.

There have been differing public reactions to the International Astronomical Union’s decision: some dismissed it as irrelevant, some convinced the scientists were fooling around. The verb “to pluto”, recognized as Word of the Year 2006 by the American Society of Dialectology, appeared in English. The word means “to downgrade in meaning or value”.

The state authorities in New Mexico and Illinois, where Clyde Tombaugh lived and worked, legislated to keep Pluto as a planet and declared March 13th as the annual Planet Pluto Day. Ordinary citizens responded with both online petitions and street protests. People who had thought of Pluto as a planet all their lives found it difficult to accept the astronomers’ decision. Besides, Pluto was the only planet discovered by an American.

Who benefits?

Pluto is the only one that has lost in status. The other dwarf planets, on the other hand, were previously classified as asteroids. Among them is Ceres (named after the Roman goddess of fertility), discovered back in 1801 by Italian astronomer Giuseppe Piazzi. For a time, Ceres was considered the missing planet between Mars and Jupiter. Still, it was later classified as an asteroid (by the way, the term was specifically coined after the discovery of Ceres and nearby large objects). The Astronomical Union decided in 2006 that Ceres was to be considered a dwarf planet.

Ceres, which has a diameter of about 950 km, is located in an asteroid belt, making it very difficult to observe. It is thought to have an icy mantle or even oceans of liquid water beneath its surface. A qualitative step in the study of Ceres was the Dawn mission, which reached the dwarf planet in the autumn of 2015.

Studying Meteorites and Cosmic Dust
Meteorites and space dust may contain information about what chemical elements and compounds were available during the formation of our solar system. Astronomers are analyzing the composition of meteorites to find out what organic molecules may have been available during the formation of Earth and other planets.

Exploring exoplanets
Exoplanets — planets that are outside our solar system — may also contain signs of life. Astronomers investigate exoplanets using a variety of methods, including the transit method, in which astronomers measure changes in a star’s brightness as the exoplanet passes in front of it.

Searching for radio signals
Astronomers examine radio waves to detect possible signals sent by intelligent life in the universe. This is called searching for intelligent signals from space.

Studying stars and galaxies
Some galaxies may contain the conditions necessary for life to emerge, such as planetary systems with planets in the habitable zone. Astronomers study stars and galaxies to determine how they form and evolve.

Studying cosmic rays
Cosmic rays can help study the origin of life because they can affect chemical compounds in space. Astronomers study cosmic rays to find out how they affect the formation of organic molecules.

Exploring interstellar space
Astronomers study interstellar space to find out what molecules and gases are present in it. They look for places where these molecules can combine to form organic molecules.

Studying Life on Earth
The study of life on Earth can also help in understanding the origins of life in the universe. Astronomers study life on Earth to understand how it originated, what conditions it needs, and what processes take place within living organisms.

Exploring unique environments
Astronomers are also investigating unique conditions in space that may contribute to the emergence of life, such as cryovolcanoes or oceans of liquid water on planetary satellites. They investigate such conditions to understand what processes might occur in them and how they might influence the emergence of life.

Gravity is the force that attracts objects of mass to one another. It is a fundamental force of nature and determines the motion of all objects in space.

When a star runs out of life, it can explode in a huge explosion called a supernova. If a star is large enough, its core can shrink to the size of a black hole. Black holes can also form when two stars merge.

There are three types of black holes: stellar, medium and supermassive. Stellar black holes form when stars die, medium black holes form when several stellar black holes merge, and supermassive black holes form in the centers of galaxies.

Black holes have a strong gravitational field, which can affect the surrounding space. They can “pull in” gas and dust from the surrounding cosmos, which leads to the formation of accretion disks. These disks can generate large amounts of energy, including X-rays.

The event horizon is the boundary of a black hole beyond which nothing, including light, can leave the black hole. If an object crosses the event horizon, it enters the black hole and cannot return.

Black holes do not emit light and therefore it is impossible to find them by direct observation. However, we can study their effects on surrounding matter. For example, we can study the motion of stars and gas around a black hole, and we can observe the effect of gravitational lensing, where a black hole bends the light of other objects in space.

Supermassive black holes are at the centers of galaxies and affect their structure and evolution. They can affect stars and gas in the galaxy, leading to the formation of new stars and changing the shape of the galaxy.

Albert Einstein’s theory of relativity describes how gravity affects space and time. It predicts the existence of black holes and explains their properties, such as the event horizon and the curvature of light around a black hole.

The study of black holes helps us better understand the fundamental laws of nature and the evolution of the cosmos. In the future, we can use technologies such as gravitational waves and observations through space telescopes to study black holes in more detail and expand our knowledge of them and their role in the cosmos.

There are several ways to discover exoplanets. One of the most common methods is the transit method. This method involves astronomers looking for planets that pass in front of their star. When a planet crosses its star, it blocks out a small portion of the light we see. This can cause small changes in the brightness of the star, which astronomers can measure.

Another method used to detect exoplanets is to measure the radial velocity of the star. When an exoplanet orbits its star, it affects the star’s gravitational field and causes it to oscillate slightly. Astronomers can measure this motion and determine if the planet is around the star and how close it is to the star.

Gravitational lensing is a technique used to detect very distant exoplanets. When an exoplanet passes between us and a star, the light from the star is bent by its gravitational field. This allows astronomers to determine the presence of a planet and its mass.

Direct observation is the method used to detect exoplanets directly through telescopes. This method is the most complex and requires the use of very powerful telescopes and equipment. Astronomers look for light that is reflected from a planet and try to distinguish it from light that is reflected from a star.

Over the past decades, we have discovered thousands of exoplanets around other stars. These exoplanets can range from gas giants to rocky planets that might look like our Earth. Thanks to these discoveries, we have begun to better understand how the formation and evolution of planets in the universe works.

One of the main questions astronomers are interested in when studying exoplanets is the search for life on other planets. We know that our planet is in the habitable zone of our star, which allows life on Earth to exist. Astronomers look for exoplanets in the habitability zone of other stars where temperatures may be suitable for life to exist.

Recently, several exoplanets have been discovered that might be suitable for life. For example, in 2016, the exoplanet Proxima Centauri b was discovered to be in the habitable zone of the star Proxima Centauri, the closest star to Earth, 4.24 light-years away. Exoplanets have also been discovered in the habitability zone of TRAPPIST-1 and LHS 1140.
