American space agency NASA has discovered another earth, where indications of an ocean full of water have also been found. NASA has claimed that its James Webb Space Telescope has accomplished this feat, this telescope has observed a distant planet i.e. exoplanet outside the solar system, and its data shows that this On the other hand, the surface of the Earth may be covered with water.
Scientists have detected the presence of methane and carbon dioxide within the atmosphere of this exoplanet.
New sphere 8.6 times larger than Earth
It is estimated that this sphere is about 8.6 times larger than the Earth - which is between the size of the Earth and Neptune. There are also speculations about the existence of a water ocean beneath the hydrogen-rich atmosphere. Along with this, a chemical has been found on this planet which points towards possible life.
Signals from the James Webb Telescope suggest that K2-18 b may be a Hycean exoplanet, with a hydrogen-rich atmosphere and possibly covered with oceans. NASA has informed on its website that preliminary information about the characteristics of the atmosphere of this habitable zone exoplanet has been obtained through the Hubble Space Telescope.
This new discovery has inspired scientists for future research, and has changed their understanding of the solar system to a great extent. Some astronomers believe that this incident raises new hopes towards the search for life on exoplanets.
There is hope for a new ocean here
K2-18b orbits the cool and small star K2-18 in the habitable zone, about 120 light-years from Earth. Distant planets like K2-18 b, i.e. exoplanets, are very different from anything else in the solar system, whose size is between Earth and Neptune. NASA scientists say that due to the lack of planets present near the solar system, they are often given less importance. However, there is active debate among astronomers regarding their atmosphere.
Cambridge University astronomer Nikku Madhusudan, who gave information about these results, said that 'Traditionally, the search for life on this exoplanet has mainly focused on small rocky planets. But large Hysene exoplanets are extremely suitable for atmospheric perception.
The presence of methane and carbon dioxide here and the lack of ammonia strengthen the scientific thinking that K2-18 b may also have a water ocean beneath its hydrogen-rich atmosphere.
NASA's Kepler Space Telescope first discovered K2-18 b in 2015, and research conducted since then has pointed to the possibility of life in it. In 2019, researchers using the Hubble Space Telescope discovered that K2-18 b has water vapor in its atmosphere.
