India, Sept. 15 -- An international team of astronomers have found traces of a rare molecule on another planet's atmosphere that hints at the possibility of extraterrestrial life. However, the most surprising bit is that the planet isn't located on some distant solar system, but is (relatively speaking) right next door, Venus.

The rare molecule is phosphine, which is made up of phosphorus and hydrogen atoms and is considered a biosignature. Jane Greaves of Cardiff University notes that on Earth, phosphine is either made industrially, or by microbes that thrive in Oxygen-free environments. "When we got the first hints of phosphine in Venus's spectrum, it was a shock!", Greaves said.
