For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

Astronomers in Canada say they have found evidence for 45 new tiny moons orbiting Jupiter, and that the planet may have a staggering 600 such moons in total.

The sun has passed from one of its 11-year activity cycles into another. Scientists predict the new cycle - Solar Cycle 25 - will be about as calm as the previous one.

Is there microbial life in the atmosphere of Earth's closest neighbor, Venus? An international team of astronomers has found tentative but highly compelling evidence.

The new work reveals dark matter haloes as active regions of the sky, teeming with not only galaxies, but also radiation-emitting collisions that could make it possible to find dark matter haloes in the real sky.

Keep track of where NASA's Mars 2020 Perseverance is on its journey through space toward its February 18, 2021, landing on Mars. This web app shows you where spacecraft is right now.

Astronomers used a radio telescope in Australia to search for artificial radio signals among 10 million stars. The search came up empty. But, they say, that's not bad news for those hoping to find intelligent extraterrestrials.

Astronomers say the nearby red dwarf star Gliese 887 appears to have more dangerous flare activity than first believed. This could make life tough - but maybe not impossible - on its family of super-Earth planets.

Although few details are known, and no images have been released, the Chinese did apparently launch a reusable spacecraft on September 4, 2020. It appears to have deployed a satellite to orbit and then returned to Earth safely 2 days later.

A new map created by a Reddit user - based on what we know about the highs and lows on Venus' surface - shows what this neighboring, cloud-shrouded, blazing hot planet might look like with oceans. Wow!
