Veryovkina Cave is the world’s deepest known cave (2212 m deep). It is located in the Arabika Massif of Gagra Mountain in the Western Caucasus. Its microbiome remains unknown because […]
We investigate how well the Large Interferometer for Exoplanets (LIFE) mission concept can detect habitable conditions on exoplanets through the presence of atmospheric water vapor as a proxy for surface […]
![[L] The detrended and phase-folded RV time series of GJ 1132 b (top) and GJ 1132 c (bottom). Different draws of the Keplerian models from our posterior are superimposed in black. The different colored markers correspond to different RV time series. Binned data points are shown as red squares.

Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of refractory elements, we can predict the […]
UC Santa Barbara doctoral candidate in physics, Skyler Palatnick, PhD ’26, has been named to Heising-Simons Foundation’s Science program’s new class of 51 Pegasi b Fellows, which he will perform […]
The recent discovery of all five canonical nucleobases in samples from Bennu provides compelling evidence that some of life’s ingredients were synthesized abiotically in the parent body of this asteroid […]
At least one large-body (diameter > 1.1 km) hypervelocity cratering event occurred during ~ 0.8-0.90 Ma (Zhamanshin, Kazakhstan) in the Middle Pleistocene Transition period.
Context. Terrestrial exoplanets are expected to host secondary, high-metallicity atmospheres derived from outgassing of volatiles such as N2, CO2, H2O, CH4, and CO. Photochemical organic hazes are likely to form […]
Ichnofossils in basaltic glass are putative microscopic trace fossils occurring on modern seafloor and throughout Earth history. While their biological origin remains debated, it is unknown why microorganisms thrive in […]
Hypervolatile species such as carbon monoxide (CO) and molecular nitrogen (N2) have been detected in comets, and could be used to constrain comet formation temperature conditions if their presence is […]
Prebiotic chemistry in nano-environments confined within catalytic mineral media is emerging as a promising frontier in origins-of-life research. Such confined spaces exhibit physicochemical properties distinct from bulk conditions, enabling out-of-equilibrium […]
