Two space probes, Hera and Europa Clipper, are ideally positioned to fly through the debris trail of interstellar comet 3I/ATLAS. This offers a rare opportunity to gather crucial data from the comet's ...

Scientists using a global array of radio telescopes have detected the universe’s lowest-mass dark object by observing how it warped light through gravitational lensing. The invisible mass, about a ...

Astronomers have discovered one of the smallest dark objects ever detected in the universe. Using a global array of radio telescopes, researchers observed how the invisible mass warped light from a ...

With the aid of a multinational network of radio telescopes, scientists have been able to detect the lowest-mass dark object ever found in the universe. The mysterious object, roughly one million ...

I/ATLAS is the third interstellar object ever discovered in our solar system. Telescope observations suggest it is a roughly 7-mile-wide (11 kilometers) comet zooming at more than 130,000 mph (210,000 ...

The vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

A large chunk of suspected space debris has been found in a remote part of the Australian desert, the country’s space agency confirmed Monday. The charred and smoldering object was found in the ...

With help from citizen scientists, astronomers have spotted the most powerful "odd radio circle" (ORC) yet. The discovery could give astronomers a better understanding of how these unusual objects — ...
