Semidiurnal atmospheric thermal tides are important for terrestrial exoplanets in the habitable zone of their host stars….
Researchers with NASA’s Cassini mission found evidence of a toxic hybrid ice in a wispy cloud high above the south pole of Saturn’s largest moon, Titan….
Since NASA’s Dawn spacecraft detected localized organic-rich material on Ceres, Southwest Research Institute (SwRI) has been digging into the data to explore different scenarios for its origin….
If life exists on Mars, it will have sought refuge underground. Trying to uncover one of the best-kept secrets in the Solar System, scientists are working a kilometre beneath the ground, with ESA astronaut Matthias Maurer joining them this week….
For scientists trying to understand what ancient Mars might have been like, the red planet sends some mixed signals. Water-carved valleys and lakebeds leave little doubt that water once flowed on the surface….
This paper provides a brief overview of the journey of molecules through the Cosmos, from local diffuse interstellar clouds and PDRs to distant galaxies, and from cold dark clouds to hot star-forming cores, protoplanetary disks, planetesimals and exoplanets….
Astrophysical observations reveal a large diversity of radii and masses of exoplanets. It is important to characterize the interiors of exoplanets to understand planetary diversity and further determine how unique, or not, Earth is….
Scientists at the University of Utah report that small seismic signals emanating from lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.
In a recent study, scientists explored the reasons behind the existence of the Indian Ocean Geoid Low, a point of low gravity found just south of the Indian peninsula.
This vegetation index, created using images taken by OSIRIS-REx’s MapCam camera on Sept. 22, 2017, shows areas on Earth with abundant plant life….
