Our Solar System may once have hosted not two, but three ice giants. This long-lost world could help explain why the outer planets and their moons look the way they do today.
A new research estimates that of order tens of millions of planetary mass objects can form in outer regions of AGN accretion disks - active supermassive black holes.
By tracking fierce winds racing through the atmospheres of seven ultra-hot Jupiters, astronomers have uncovered the strongest evidence yet that magnetic fields shape weather on worlds beyond our Solar System.
Using the spectral data, James Webb Space Telescope, astronomers have detected methane on 3I/ATLAS. This is the first direct detection of methane in an interstellar object.
The Northwest Africa (NWA) 12774, an angrite meteorite, appears to be a fragment of a vanished protoplanet, offering the strongest evidence yet that a large planetary body formed and was later destroyed during the Solar System’s chaotic infancy.
In a new study researchers say that a cut sample of the creature, a species called Psolus fabricii ( Sea Cucumber), has survived for three years while being kept in natural seawater, growing and repairing all on its own.
Researchers traced long-period transient bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion.
Working with the JWST, researchers have now found a SMBH with 50 million solar masses that appears to predate its host galaxy.
Beneath a crater gouged by a massive impact around 42,000 years ago, several stromatolites were identified. This discovery suggests that the heat generated by the impact may have created a hydrothermal environment.
The space rock has been given the name 2026 JH2 and is thought to be up to around 35 metres wide - around the length of a 5-a-side football pitch.
Shalbatana Vallis is an impressive channel near Mars’s equator. It is 1300 km in length - around the length of Italy. Formed formed around 3.5 billion years ago, when huge quantities of groundwater rose up to Mars’s surface.
Observations suggest that Nereid is no party crasher like Triton and likely survived by escaping into its extreme, elliptical orbit around Neptune.
New gamma-ray observations from NASA’s Fermi Space Telescope suggest ultra-magnetic neutron stars called magnetars could be fueling superluminous supernovae.
New simulations suggest a violent collision 11 billion years ago reshaped our Galaxy and triggered a burst of star formation.
Our solar system has been moving through the local interstellar cloud, left by a supernova, for over past 80,000 years.
