Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery.

The survey, known as ALMA to Resolve exoKuiper belt Substructures (ARKS), focused on debris disks. Debris disks are vast belts of dust and ice left behind after planets finish forming. These ...

In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth. The Venusian space rocks are ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...
