A small asteroid, 2020 HS7, passed at nearly the distance of geosynchronous satellites.

Earth and Mars both are known to have swirling dust devils moving along their surfaces. Saturn's large moon Titan might have them, too, according to a new study. If so, NASA's planned Dragonfly mission will be able to find them.

A cloudy sky last night prevented the online viewing of large, close-passing asteroid 1998 OR2. The Virtual Telescope Project will be trying again today to show you the asteroid, which passed us earlier today.

For the first time, the entire lunar surface has been completely mapped and uniformly classified by scientists from the USGS Astrogeology Science Center, in collaboration with NASA and the Lunar and Planetary Institute.

The Hubble Space Telescope has provided astronomers with the sharpest view yet of the breakup of comet C/2019 Y4 (ATLAS).

In the first discovery of its kind, researchers in France have found 19 asteroids in our solar system - between the planets Jupiter and Neptune - that they say are likely of interstellar origin.

Researchers at NASA’s Goddard Space Flight Center, looking at old data from Voyager 2, have found evidence that plasmoids are slowly causing Uranus' atmosphere to leak into space.

LIGO and Virgo detectors have now captured the first gravitational waves from a binary black hole merger where the black hole masses are unequal.

The Hubble Space Telescope was launched on April 24, 1990. It's spent the past 3 decades acquiring magnificent images of distant space objects, providing a time machine that's taken astronomers back to when the universe was less than a billion years old.

Fomalhaut b was thought to be one of the few exoplanets photographed so far, but new observations from the Hubble Space Telescope show it's really an expanding dust cloud.
