Chinese astronomers hope to establish a major observatory program on the roof of the world, the Tibetan Plateau, with new research arguing for pristine observing conditions nestled in the uplands.

SpaceX's Starlink satellites are involved in about 1,600 close encounters between two spacecraft in low Earth orbit every week, according to available data. That’s about 50% of all such incidents.

Astronomers discovered a 3,000-light-year-long 'break' in the Milky Way's Sagittarius spiral arm, jutting out at a wild angle.

The partial breakup of China's Yunhai 1-02 military satellite on March 18 is no longer mysterious.

But don't expect it to actually launch so soon.

Scientists used Saturn's famous rings as a seismograph to study processes in the planet's interior. The researchers found its core is like a soup consisting of rocks, ices and metallic fluids.

Theories that try to explain these big metaphysical mysteries fall short, making agnosticism the only sensible stance.

Here's the historical significance of the black-and-white photo that Elon Musk tweeted showing SpaceX's next Starship prototype.

The particles used were spooky virtual particles, conjured from a disturbance between two electromagnetic fields.

An Indian rocket carrying a new Earth-observation satellite for the Indian Space Research Organisation (ISRO) suffered a catastrophic failure shortly after launching early Thursday (Aug. 12).

Scientists think they know the origin of the image, but they’re still baffled by its bizarre shape.

Astronomers say a weird star careening through the Milky Way could have survived the explosive powers of a supernova.

Because of anticipated delays in spacesuit development, it is "not feasible" for NASA to land humans on the moon by the agency's hopeful deadline of 2024, a report has found.
