Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...

The planets in our solar system grew out of a disk of material that swirled around our Sun. Inner rocky planets formed as tiny grains stuck together ...

One way gas giants form is through core accretion, where solid cores gradually grow in a disk by pulling in rocky and icy pebbles until they become massive enough to attract the gas that surrounds ...

Astronomers have caught a free‑floating “rogue planet” in the act of bulking up at a rate that defies intuition, swallowing ...

The canonical image of a supermassive spacetime abyss anchored at the center of our galaxy, Sagittarius A*, is challenged by ...

Hubble observations reveal a giant, turbulent planet-forming disk that may reshape theories of how planetary systems develop.

Astronomers have continued to monitor it ever since. Far from fading again, the TDE has grown 50 times brighter, and that brightness continues to increase. The black hole’s energy emission might not ...

With this new survey, astronomers have gained a peek inside a stage of exoplanet system formation they have yet to fully ...

An international team of astronomers, led by Weichen Wang of the University of Milan, Italy, discovered a massive and ...
