A sprinkling of radioactive plutonium atoms hidden in the ocean floor may trace back to a cosmic cataclysm more than 100 million years ago.
Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock.
Scientist has built a "mini-universe" that takes a step toward answering one of science's biggest questions: "What is time?
A gravastar (gravitational vacuum star) is a hypothetical cosmic object proposed as an alternative to a black hole.
Astronomers have discovered the earliest known flickering quasar, whose light has traveled more than 13 billion years to reach us.
A study published last year claiming the growth of the universe is slowing has been refuted. Our universe's expansion is still accelerating despite recent claims suggesting otherwise, an international team of astrophysicists say.
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.
