The cameras aboard the International Space Station may be ready, but it's still not clear where to point them in order to capture the April 8 total solar eclipse.

The Odysseus lander powered down yesterday as it braces for two weeks of lunar night. This farewell image may be its last.

Reports that Russia may be developing an anti-satellite nuclear weapon have many rightfully alarmed. Here's why this type of technology is a danger to space exploration at large.

Intuitive Machines successfully landed its spacecraft on the moon's south pole in a historic mission that puts the U.S. back on lunar soil for the first time in over 50 years.

Europe's ERS-2 climate satellite has burnt up over the Pacific Ocean in an uncontrolled reentry after 30 years in orbit. No damage from falling debris has been reported.

The European Space Agency's ERS-2 Earth observation satellite was spotted in space as it prepares to make a fiery reentry into Earth's atmosphere on Feb. 21.

Twinkling stars can throw off telescope observations. To correct that, observatories like the Gemini North telescope in Hawaii create 'artificial stars' with lasers to hone their equipment.

Private companies like SpaceX are crowding Earth's atmosphere with ever-increasing numbers of satellite 'megaconstellations'. For astronomers, the toll of these bright, ubiquitous objects is already painfully clear.

Space is a harsh place, with freezing temperatures, harmful radiation and a near-vacuum. So, what would happen to the body of an astronaut that was exposed to space's elements?

On Feb. 14, the U.S. Congress learned that Russia is creating a mysterious space-based nuclear weapon to target satellites. The capability is still in development and the launch of such a weapon does "not appear imminent."
