Researchers have detected hints of molecules known to be produced by marine organisms on the exoplanet K2-18 b, providing "the strongest evidence yet" of life outside the Solar System. While the discovery is exciting, more data is needed to confirm whether the molecules are indeed produced by life or through other chemical processes. The exoplanet, over 8.5 times as massive as Earth, lies 120 light-years from Earth and orbits the star 'K2-18'.
Chandrayaan-1 X-ray fluorescence spectrometer detected sodium from its characteristic line in X-rays which opened up the possibility of mapping the amount of sodium on the moon, ISRO said.
A team of researchers has revealed that the old adage "what goes up must come down" is ringing true for an immense cloud of hydrogen gas that is heading towards our galaxy at nearly 7 lakh miles per hour.
The finding may help understand the types of planetary systems that exist beyond our own.
The most luminous galaxy in the universe -- a so-called obscured quasar 12.4 billion light-years away -- is so violently turbulent that it may eventually jettison its entire supply of star-forming gas, a new study has found.
