Is there life on Venus? For more than a century, scientists have pondered this question. Now, there is renewed interest in Venus as a place that could support living organisms.

It's hard to imagine a more inhospitable world than our closest planetary neighbor.

The atmosphere of Venus remains mysterious, with many outstanding chemical connundra. These include: the unexpected presence of ~10 ppm O2 in the cloud layers; an unknown composition of large particles in the lower cloud layers; and hard to explain measured vertical abundance profiles of SO2 and H2O.

Scientists have proposed a new theory which suggests that possible lifeforms in the clouds of Venus could be setting off a cascade of chemical reactions that is making the environment much more habitable.

Venus Life Finder Mission Study

The Venus Life Finder Missions are a series of focused astrobiology mission concepts to search for habitability, signs of life, and life itself in the Venus atmosphere.

We report a model study on the effects of clouds on emission spectra of super-Venus planets. Our goal is to assess possible ways to identify characteristic spectral features due to clouds.

The initial reports of the presence of phosphine in the cloud decks of Venus has led to the suggestion that volcanism was the source of phosphine, through volcanic phosphides ejected into the clouds.

The potential detection of ppb levels phosphine (PH3) in the clouds of Venus through millimeter-wavelength astronomical observations is extremely surprising as PH3 is an unexpected component of an oxidized environment of Venus.

DAVINCI Venus Mass Spectrometer

DAVINCI will send a meter-diameter probe to brave the high temperatures and pressures near Venus' surface to explore the atmosphere from above the clouds to near the surface of a terrain that may have been a past continent.

Earth has had oceans for nearly four billion years and Mars had lakes and rivers 3.5-3.8 billion years ago. However, it is still unknown whether water has ever condensed on the surface of Venus because the planet - now completely dry - has undergone global resurfacing events that obscure most of its history.
