Life On Lava: How Microbes Colonize New Habitats

by Keith Cowing

Life has a way of bouncing back, even after catastrophic events like forest fires or volcanic eruptions. While nature’s resilience to natural disasters has long been recognized, not much is […]

Atmospheric Retrievals Suggest The Presence of a Secondary Atmosphere and Possible Sulfur Species on L 98-59 d from JWST NIRSpec G395H Transmission Spectroscopy

by Keith Cowing

L 98-59 d is a Super-Earth planet orbiting an M-type star. We performed retrievals on the transmission spectrum of L 98-59 d obtained using NIRSpec G395H during a single transit, […]

Assessing the Detectability of Europa’s Seafloor Topography from Europa Clipper’s Gravity Data

by Keith Cowing

Due to its size and tidal heating, Europa may potentially possess active volcanism and hydrothermal circulation at its seafloor.
