Astrophysics professor finds signs of life on faraway planet
Potential signs of life have been detected outside our solar system, according to a new research headed by a Cambridge scholar using NASA’s James Webb telescope.
Professor Nikku Madhusudhan, an astrophysicist from Cambridge’s Institute of Astronomy, found evidence of dimethyl suplphide (or DMS) on the planet K2-18b, 120 light years from Earth.
DMS is a surface sea level, ocean-produced sulphur compound, which is released into the atmosphere, and is critical to the “global sulphur cycle”.
On Earth, it is only produced by life.
“The bulk of it in Earth’s atmosphere is emitted from phytoplankton in marine environments,” Professor Madhusudhan explained.
Although the James Webb Space Telescope has detected the presence of DMS in the chemical signatures of the planet’s light, researchers have stressed that the finding is uncertain and requires further investigation.
Madhusudhan stipulates that the finding is tentative an
