Mimas, a small moon of Saturn, is heavily cratered and lacks the typical characteristics of an ocean-bearing moon, such as the active surface of Enceladus....
Enceladus, the sixth-biggest moon of Saturn, is a top candidate in the search for extraterrestrial life in the Solar System.
An artist’s impression of...
Using data from the NASA/ESA Hubble Space Telescope and NASA’s retired Spitzer space telescope, astronomers have discovered that two exoplanets around...
The Chicxulub-like asteroid crash landed in shallow ocean waters in the Martian region of Chryse Planitia 3.4 billion years ago (Hesperian period) and...
An analysis of chromium isotopes in Martian meteorites suggests that approximately 4.5 billion years ago, there was enough water for the entire planet...
The Devonian period, which occurred 419 to 358 million years ago, prior to the evolution of life on land, is known for a series of catastrophic mass extinction...
Mass extinctions are well recognized as significant steps in the evolutionary trajectory of life on Earth. In new research, geobiologists from Virginia...
A major question in Mars history is whether the planet had an ocean in its northern hemisphere. New research provides evidence for a northern ocean or...
In the search for life beyond Earth, subsurface bodies of water in the outer Solar System are some of the most important targets. That’s why NASA and...
About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. The impact eradicated...
A team of researchers from Curtin University and Peking University has used a supercomputer to simulate how a supercontinent forms and found that because...
Enceladus is one of the prime targets in the search for life in our Solar System. Observations made by NASA’s Cassini spacecraft show that this small...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and the SPIRou spectropolarimeter on the 3.6-m Canada-France-Hawaii telescope have...
The underwater snow is known to form in low temperature environments, e.g., beneath ice shelves, on Earth. New research led by University of Texas at Austin...
In a study published this week in the journal Nature Communications, scientists tested the hypothesis that fine and coarse marine aerosols have opposite...
Someday, dozens of tiny swimming robots could whisk through the water beneath the icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking...
After nine years of gathering, cleaning, processing and interpolating data, an international team of researchers this week released the second version...
Otodus megalodon, the largest shark that ever lived on Earth, most certainly reached at least 15 m (50 feet) in total length based on its gigantic teeth....
Mimas, the smallest and innermost of Saturn’s eight main moons, may be warm enough to harbor a global, liquid water ocean beneath a 24-31-km (15-19-mile)...
