The confirmed number of exoplanets reached 5,000 in 2022, 30 years after the discovery of planets outside the solar system, including a variety of distant planets, including a super-Earth, a gas giant like Jupiter, a ice like Neptune, and others.
According to the site,RT“Although planetary scientists have discovered thousands of these strange spaceworlds, it is likely that there are more than a trillion exoplanets in our Milky Way alone, and here we present a series of recent exoplanet discoveries that were announced in 2022..
A planet that harbors metal clouds and rains precious stones
Scientists recently discovered that airborne minerals and gemstones are more likely to be on the colder side of the Earth WASP-121 bIt is an extrasolar planet 855 light-years from Earth.
There, it’s cold enough for minerals in the upper atmosphere — such as magnesium, iron, vanadium, chromium and nickel — to condense into clouds.
According to Thomas Mikal-Evans, an astronomer at the Max Planck Institute for Astronomy and lead author of the research, these clouds may resemble dust storms on Earth. Some clouds may be colored blue or red, while others are gray or green. Sometimes, it can condense into drops which ultimately means that the gems are falling from the sky.
Alien planet in the shape of a rugby ball
Although most planets are spherical, WASP-103b not like that.
He found a telescope Cheops space, of the European Space Agency WASP-103-b – And it’s a planet twice the size of Jupiter, not because it orbits its star in a single day. This causes a severe distortion on the planet due to the gravitational influence it is exposed to due to its star.
Eventually, this gravitational pull warped the spherical planet into a rugby ball-like shape.
Rare find on ‘Super Neptune’
About 150 light-years from Earth, astronomers have discovered a “super-Neptune” (a planet slightly larger than Neptune) with water vapor in its atmosphere. This is rare.
And NASA wrote: “150 light-years away, that is TOI-674b Astronomically close, which is one reason scientists can derive the chemical makeup of its atmosphere. Many questions remain, such as how much water vapor its atmosphere contains, but by looking at the atmosphere TOI-674b It’s much easier than observing the atmospheres of many exoplanets, making it a prime target for deeper investigations“.
An exoplanet is still forming
Planetary scientists have discovered a giant exoplanet that is still forming AB Auriga b.
The more than 30-year-old Hubble Space Telescope photographed the planet, which is developing into a still young, volatile disk of gas and dust called a protoplanetary disk..
The age of the newborn star of the solar system is only two million years. (The Sun, for example, is more than 4.5 billion years old.).
And the new planet is gigantic. Scientists believe it is nine times larger than Jupiter. It orbits far from its star, about 8.6 billion miles away. This is more than double the distance Pluto is from the sun.
And unlike most planets, which are thought to have formed when smaller objects in the planetary disk collided and grew into large, hot planetary bodies, it could be AB Auriga b It was formed when its cooled disk shattered into large chunks.
A huge ocean probably covers the entire exoplanet
A hundred light-years away in the universe, a vast ocean could well up on an entire distant planet.
And last August, astronomers announced that the exoplanet TOI-1452b Near-Earth in size and located in a region of its solar system where liquid water could exist, and large quantities of water – many times the amount of water on Earth – could be responsible for the planet’s low density (as opposed to a teeming world with rocks and minerals)..
Scientists have revealed that oceans could make up about 30 percent of the land mass TOI-1452 b. For comparison, on Earth, water makes up only 1% of the planet’s mass.
A strange planet that looks like a marshmallow
Scientists find out TOI-3757 ba giant gas planet with the density of “marshmallow” or “marshmallow”, orbiting a cold red dwarf star located 580 light-years from Earth.
The planet orbits a common, albeit intriguing, type of star called a red dwarf. These stars are much smaller and dimmer than the Sun, but they are very fickle: they emit violent flares that can make nearby planets inhospitable..
An unprecedented discovery on a planet 700 light years away
Astronomers have found the outer planet WASP-39 b, a hot gas giant that orbits a star 700 light-years away. For the first time, they have discovered a ‘complete list’ of atoms and molecules in an exoplanet’s clouds, some of which interact.
Starlight often fuels chemical reactions on a planet, a process called photochemistry. This is what happens WASP-39 b.
“Planets are sculpted and transformed by rotating within the radiation bath of the host star,” Natalie Batalha, an astronomer at the University of California, Santa Cruz, who contributed to the new research, said in a statement. On Earth, these transitions allow life to thrive“.
Suggests a chemical supply of WASP-39 b A history of collisions and mergers of smaller bodies called planetesimals (planetesimals) to create the planet.
Evidence for the existence of “water worlds” in deep space
Scientists have discovered two ‘water worlds’, in the same solar system, which are believed to be teeming with water. Water can account for up to half the mass of these planets.
These two watery worlds, which are unlike any planets seen in our solar system, are located in a planetary system located 218 light-years from Earth in the constellation Lyra..
The two planets are called one name Kepler-138 c ANDKepler-138 dnamed after the Kepler telescope (Kepler Space Telescope) by NASA, which has identified thousands of exoplanets and revolutionized our understanding of what lies beyond our solar system, in the deep universe.
