Space: Astronomers have discovered new types of habitable planets

Cambridge University researchers have discovered a new type of habitable planet. Their discovery “will completely change the understanding of life in the universe”.

Cambridge – This could be a big step in the search for life in space: astronomers have discovered a new kind of habitable planet. They are completely different from Earth: warmer, but with a lot of hydrogen in the oceans and atmosphere.

Discoverers at the University of Cambridge in the UK named this new class of oceans – “hydrogen” (Latin for hydrogen) and the ocean. The reason: The newly discovered planets have a hydrogen-rich atmosphere and a warm surface – covered by oceans.

Researchers refute previous assumptions

Until now, exoplanets – that is, celestial bodies outside the solar system – between Earth and Neptune have often been called super-Earths or mini-Neptunes. The latter is smaller than our Neptune – but much larger than our home planet, which cannot be made of rocks. For this reason, researchers previously thought that their hydrogen-rich atmosphere was too hot and that the air pressure was too high to survive.

Cambridge scientists have this assumption Dr. நிக்கு மதுசூதன் Now the Mini-Neptune K2-18b is basically denied. Because: conditions there can make life possible, as their study showed. She is me Journal of Astronomy Published.

Hyson planets are 2.6 times larger than Earth

Thus, Hyson planets can be up to 2.6 times the size of Earth and have a temperature of up to 200 degrees Celsius in the atmosphere, but conditions in their oceans allow microbes to live – just like Earth.

“The Hijian planets open up completely new possibilities for us in our search for life,” explains Dr. Alcoholism. This is because the vast majority of exoplanets discovered so far contain such celestial bodies. However, they have not yet been fully explored – in contrast to Super-Earths.

“If we see a signature of life there, it will completely change our understanding of life in the universe.”

In their search, the researchers primarily called biomarkers such as methyl chloride and dimethyl sulfide. They represent life on planets that do not have an oxygen-rich atmosphere like Earth.

Researchers now want to stare at the planets

Dr. Alcoholism. “But we think the Hyson planets now offer the best chance of finding traces of biological signatures.”

The set of planets that Cambridge scientists have identified as Hyson is now being explored in more detail by the James Webb Space Telescope (JWST). All of these celestial bodies are located in the solar system known as the “red dwarf” and are not far from astronomical conditions in 35 to 150 light years.

This includes K2-18b. Researchers want to examine it more closely with telescopes. “If we see a life signature there, it will completely change our understanding of life in the universe,” says Dr. Alcoholism. (John Went)

An asteroid is dangerous to Earth. According to NASA, an impact is greater than previously thought.
