The inner terrestrial protoplanets accrete early, inherit a substantial amount of radioactive 26Al, and hence melt, form iron cores, and degas their primordial volatile abundances…

This artist’s concept shows the planet KOI-5Ab transiting across the face of a sun-like star, which is part of a triple-star system located 1,800 light-years…
Artist’s conception of a brown dwarf. Credits: NASA/ESA/JPL Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. University…
On Earth snow condenses at altitude because air dilates during ascending movements, and thus cools (at the rate of 1°C approximately every 100 m). On…
This image shows the disc around the young star AB Aurigae in polarized near-infrared light as seen with the European Very Large Telescope’s SPHERE instrument.…
Artist’s composition of the two brown dwarfs, in the foreground Oph 98B in purple, in the background Oph 98A in red. Oph 98A is the…

[embedded content]This video is a full-globe map of the distant planet Neptune, created from Hubble Space Telescope data taken January 7-8, 2020. The movie reveals…
In this artistic rendering of the Tau Boötes b system, the lines representing the invisible magnetic field are shown protecting the hot Jupiter planet from…
Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and…
The 11-Jupiter-mass exoplanet called HD106906 b occupies an unlikely orbit around a double star 336 light-years away and it may be offering clues to something…

Illustration of solar wind flowing over asteroids in the early solar system. The magnetic field of the solar wind (white line/arrows) magnetizes the asteroid (red…
Giant planets that developed early in a star system’s life could solve a mystery of why spiral structures are not observed in young protoplanetary discs,…
This artist’s concept depicts the early Martian environment (right) – believed to contain liquid water and a thicker atmosphere – versus the cold, dry environment…
Black Beauty. Martian meteorite NWA 7533 is worth more than its weight in gold. Credit: © University of Copenhagen/Deng et al. A meteorite that originated…
This image shows a triple crater in the ancient martian highlands. The largest crater measures 45 km across, and the smallest 28 km. There are…
New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. Credits: NASA/JPL-Caltech/Space Science Institute Where were Jupiter and Saturn…
Scientists recently reported the discovery of the gas phosphine around Venus, which may point to microbial life. Venus is the second planet from the sun…
The lightning phenomenon known as a sprite depicted at Jupiter in this illustration. Jupiter’s hydrogen-rich atmosphere would likely make them appear blue. In Earth’s upper…
