The growing problem of space junk poses a risk to future space missions, but the solution isn't going to be easy.

It's been quite an eventful year for NASA's Perseverance Mars rover.

China's Zhurong rover has quietly clocked up 1,900 feet (585 meters) of driving on Mars and has been using its science instruments to check out nearby geologic features in Utopia Planitia.

Today (July 30), Space Chat will explore what's new in space, including Boeing's delayed Starliner launch, Russia's misbehaving module and all of the crazy new science emerging.

New data from the European Gaia mission help shed light on the nature and origins of the spiral structure of the Milky Way.

Amateur photographer Joseph Baxter travelled 250 miles (400 kilometers) to capture the successful return to flight of Rocket Lab's Electron rocket on Thursday (July 29).

Bright reflections that radar detected beneath the south pole of Mars may not be underground lakes as previously thought but deposits of clay instead, a new study finds.

A pair of astronomers have proposed two new strategies for preventing possible asteroid impacts.

A fizzled example of a gamma-ray burst, the most powerful kind of explosion known in the universe, suggests these outbursts can be surprisingly brief, researchers say.

Never-before seen slow waves of plasma on the surface of the sun have been discovered in data gathered by NASA's Solar Dynamic Observatory over the past ten years.

For the first time ever, scientists have seen the light "echoing" from behind a black hole.

When Earth's sun grows into a red giant 5 billion years from now, solar wind will shred our planet's magnetic field to bits.

It's hard for an exoplanet to keep itself together in the neighborhood of two parent stars.

If you were to place a galaxy behind the black hole and then look off to the side, you'd see a distorted image of the galaxy. Here's why.

Some astronomers suggest setting up a "SatHub" to address the growing threat that satellite megaconstellations pose to the night sky — but funding and support are necessary to make it happen.

The moon is a great place to hunt for ripples in space-time, a new study argues.

In the wisp-thin sky of Jupiter's moon Ganymede, the largest satellite in the solar system, astronomers have for the first time detected evidence of water vapor, a new study finds.

A German X-ray mission is mapping the distribution of black holes and neutron stars in the Universe, having discovered over two million such new objects in less than two years since its launch.
