When you look at the solar system, you might notice that the planets' orbits are tilted, and oddities in the protoplanetary ...

Astronomers using NASA’s Hubble Space Telescope have measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the ...

All the planets orbit in roughly the same plane because they formed from a single rotating disk of gas and dust — the solar nebula — that flattened as it spun around the young Sun. The shared origin ...

The gravitational influence of dark matter on stellar motions within galaxies, particularly the high velocities of stars in the Milky Way, is the primary evidence for its existence. This influence is ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.
