Venus

In 2020 an international team of astonomers made a surprising discovery using the James Clerk Maxwell telescope in Hawai'i. They found evidence that the atmosphere of the planet Venus contains tiny amounts of phsophine gas.

The surface of Venus is dotted with ring-like structures named coronae, produced by volcanic activity. They appear to be much like the Hawaiian islands on Earth, which are products of volcanic activity from a plume of hot material welling up from Earth’s mantle.
