Unexplained gas on Planet Venus may hint at life

 Astronomers have detected in the atmosphere of Planet Venus the presence of phosphine gas which on Earth is associated with life, microbes living in the guts of penguins and swamps. Its presence 50km up from the planet’s surface poses questions contained in a new paper just published by Prof. Jane Greaves from Cardiff University and colleagues in the journal Nature Astronomy. They detail their observations of the Venus phenomenon but offer no answers to their questions.
