Astronomers using the NASA/ESA Hubble Space Telescope observed Jupiter’s most distinctive feature, the Great Red Spot, with on eight dates over a single,...
In a new study, astronomers compared high-resolution images of Uranus from the NASA/ESA Hubble Space Telescope to the more-distant view from NASA’s New...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
In August 2024, ESA’s JUpiter ICy Moons Explorer (JUICE) made history with a daring Moon-Earth flyby and double gravity assist maneuver. As the spacecraft...
The Moon may have been captured during a close encounter between a young Earth and a terrestrial binary (a system of the Moon and another rocky object),...
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...
