Scientists reveal the makeup of exoplanets known as hot Jupiters

Hot Jupiters – giant gas planets that race around their host stars in extremely tight orbits – have become a little bit less mysterious...

Scientists find strange black superionic ice that could exist inside other planets

Scientists used diamonds and a beam of brilliant X-rays to recreate the conditions deep inside planets, and found a new phase of water called...

Scientists find evidence of a giant impact that occurred in a nearby star system

Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the...

47 lunar fragments help fill gap of two billion years in lunar history

China's Chang'E-5 lunar sampling mission returned the first lunar samples since the Apollo and Luna missions, the last of which was in 1976. The 3.8...

Astronomers see white dwarf switch on and off for the first time

Scientists propose new way to defend the Earth against cosmic impacts

In February of 2013, skywatchers around the world turned their attention toward asteroid 2012 DA14, a cosmic rock about 150 feet (50 meters) in...

China’s FAST telescope could detect self-replicating alien probes

One of the most challenging questions to answer when confronting the Fermi Paradox is why exponentially scaling technologies haven’t taken over the universe by...

Early solar system had a gap between its inner and outer regions, shows study

In the early solar system, a “protoplanetary disk” of dust and gas rotated around the sun and eventually coalesced into the planets we know...

How do ice giants like Neptune maintain their magnetic fields?

A layer of “hot,” electrically conductive ice could be responsible for generating the magnetic fields of ice giant planets like Uranus and Neptune. New work...
