While the composition of gas and dust in a molecular cloud is fairly uniform, everything changes once a star begins to form.

rock and dust. Uranus and Neptune come next. Whilst unmanned spacecraft have approached the gas planets, actual landings are not possible because of the lack of solid surfaces. The gas planets are ...

Opinions expressed by Forbes Contributors are their own. I cover aerospace, astronomy & hosted The Cosmic Controversy Podcast. This artist’s concept shows what the exoplanet WASP-107 b could ...

Planets form in discs of gas and dust around young stars. While the gas component dominates the mass of the disc typically by a factor 100, the dust component is much easier to observe. By looking at ...

I cherish my fairly sharp memories of the 2016 launch version of No Man's Sky, inasmuch as the contrast renders the ...

A recent multi-institutional study spearheaded by NASA has revealed the most volcanic place we know of. The planet, coined L 98-59 b, seems to be perpetually reshaped by eruptions more violent and ...

Every time a planet has been found orbiting its star that closely before, it has either been a huge gas giant, similar to Jupiter, or a barren tiny rock planet smaller than Earth. "We expect ...

New James Webb Space Telescope observations of a star cluster called NGC 346 are shedding light on how, when and where planets formed in the early universe.

It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the ...

Planets are formed when dust and rock in a disk around a young star collide ... It all begins in a disk-shaped cloud of gas (99%) and dust (1%)—the protoplanetary disk. Here, dust particles ...
