Using data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide...
During the Mesozoic era, between 250 and 120 million years ago, an ancient seafloor sank deep into Earth in the East Pacific Rise, a tectonic plate boundary...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
Breakup of an asteroid passing within Earth’s Roche limit likely formed the debris ring during the middle Ordovician period, according to new research...
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
Using images from the JunoCam instrument aboard NASA’s Juno spacecraft, planetary scientists have spotted a fresh volcano with multiple lava flows and...
The images in the Martian Cloud Atlas have been captured by the High Resolution Stereo Camera (HRSC) instrument on ESA’s Mars Express spacecraft.

At least 140 million Sun-like stars in our Milky Way Galaxy are likely to have experienced a similar stellar flyby, according to new research by a team...
Mars’ water history is fundamental to understanding an evolution of Earth-like planets. Water escapes to space as atoms, and hydrogen (H) atoms escape...
Jupiter’s moon Ganymede has an ancient impact structure called a furrow system. This system is the largest impact structure in the outer Solar System,...
First hypothesized more than 60 years ago, the ambipolar electric field is a key driver of the polar wind, a steady outflow of charged particles into space...
Using data gathered by the Advanced Stellar Compass (ASC) and the Stellar Reference Unit (SRU) onboard NASA’s Juno orbiter, scientists have produced...
Although Venus is sometimes referred to as Earth’s twin, its current surface conditions are drastically different, making it inhospitable to life. Not...
Water is an important component of exoplanets, with its distribution, that is, whether at the surface or deep inside, fundamentally influencing the planetary...
TRAPPIST-1, an ultracool dwarf star located 38.8 light-years away in the constellation of Aquarius, hosts seven planets. The period ratios of neighboring...
Chloride deposits are markers for early Mars’ aqueous past, with important implications for the understanding of the Martian climate and habitability....
New data about the Martian crust gathered by NASA’s InSight lander allowed geophysicists at the University of California San Diego and the University...
One-third of Mars’ surface has shallow-buried water, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require...
This new image from the High Resolution Stereo Camera (HRSC) onboard ESA’s Mars Express spacecraft shows Caralis Chaos, broken-down and dried-up remnants...
