Cassini Study Found Organics From An Ocean Inside Enceladus

by Keith Cowing

NASA’s Cassini spacecraft captured dramatic plumes, both large and small, spray water ice out from many locations along the famed ‘tiger stripes’ near the south pole of Saturn’s moon Enceladus.

From Underground Oceans To Continents: A Glimpse Into The Water Inventory On Rocky Planets Using Host Star Abundances

by Keith Cowing

The amount of surface water is thought to be critical for a planet’s climate stability and thus habitability.

Where Water Comes From: A New Clue From Alien Worlds

by Keith Cowing

For decades, scientists believed that Earth’s water originated far from the sun. In the cold outer reaches of the solar system, water-rich bodies formed and later migrated inward, delivering water […]

New Analytical Methodology to Reveal Biosignatures on Mars and Ocean Worlds

by Keith Cowing

Terrestrial analog environments and their microbial communities are key elements to prepare for the exploration of extraterrestrial planetary environments that potentially sustained, or even may still sustain, the (bio)chemistry necessary […]

Probing The Origin Of Water In Planets Within Habitable Zones By Habitable Worlds Observatory

by Keith Cowing

How do habitable environments arise and evolve within the context of their planetary systems? This is one fundamental question, and it can be addressed partly by identifying how planets in […]

Born Dry or Born Wet? A Palette of Water Growth Histories in TRAPPIST-1 Analogs and Compact Planetary Systems

by Keith Cowing

It is still unclear whether exoplanets in compact multiplanet systems such as TRAPPIST-1 are able to accrete large quantities of volatiles, grow to sufficient mass, and maintain robust atmospheres and […]
