Astronomers may have discovered a new type of planet beyond our solar system, according to new research.
The exoplanet, named “L 98-59 d,” was first identified in 2019, but further observations using high-powered telescopes have allowed scientists to get a better understanding of its climate.
Researchers now know that L 98-59 d has some unusual characteristics. It is covered in oceans made of magma and has an atmosphere made of sulfur, according to a paper published Monday in Nature Astronomy.
It is a rocky planet with a radius about 1.63 times larger and mass about 1.64 times that of Earth’s, according to NASA.
This would make L 98-59 d, which is 35 light years away from Earth, an unlikely environment to sustain life.
The exoplanet’s atmosphere contains gases like water, sulfur dioxide and hydrogen sulfide, which can smell like rotten eggs, especially when burned.
L 98-59 d was detected by the James Webb Telescope, the most powerful telescope ever put into space. Since 2021, the telescope has made several stunning discoveries as it orbits the sun, including several exoplanets that were previously not visible to astronomers.
