ESA's Solar Orbiter captured views of the planet Mercury passing in front of the Sun. Multiple instruments aboard the ...

Gaia-4b is the most massive planet known to orbit a low-mass star. Also, see an animation for Gaia-5b, a brown dwarf orbiting a low-mass star. They were detected by the European Space Agency’s Gaia ...

Astronomical phenomena tend to occur over timespans that dwarf our human scale—a galaxy changes over millions and billions of years, not decades. But a new timelapse of observations of a distant star ...

SpaceX has delivered a new animated look at the launch of Starship to Mars. See the launch, Super Heavy booster re-entry and ...

In a solar system far, far away, astronomers have discovered evidence of possible "sibling" planets sharing the same orbit. The researchers detected a cloud of debris in the same orbital path as an ...

The vast majority of exoplanets that have been discovered are within star systems broadly similar to our solar system: one (or sometimes two or more) stars at the center, with planets orbiting at a ...

In a real-life twist on Star Wars' Tatooine—a harsh desert planet with twin suns and a criminal underbelly—astronomers have found a bizarre new world that orbits two stars at a perfect right angle.

In our Solar System, the planetary orbits all have a similar orientation. Their orbital planes vary by a few degrees, but roughly the planets all orbit in the same direction. This invariable plane, as ...

Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a ...

An ALMA telescope image shows two potential exoplanet bodies that appear to orbit a star on the same orbit. Credit: ALMA (ESO / NAOJ / NRAO) / Balsalobre-Ruza et al. Astronomers think they've found ...
