Astrophysicists are mapping a vast, hidden structure in space that appears to guide matter and radiation along a kind of interstellar highway stretching from our solar neighborhood to distant stars.

Currently, the closest exoplanet to Earth is Proxima Centauri b, which orbits the star Proxima Centauri, located 4 ...

Astronomers have revealed new details about the makeup and age of a visiting comet that was born around a distant star. They conclude that the composition of 3I/Atlas is strikingly different from any ...

The earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as it traveled through our solar system—and how other distant solar systems ...

Astronomers using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have found evidence of a Jupiter-mass object orbiting a brown dwarf in the CD-35 2722 system, a discovery ...

A team of astronomers from the University of Montreal has discovered a new potentially habitable exoplanet orbiting the red dwarf star L 98-59, 35 light-years from Earth. This discovery means there ...

A Jupiter-size exoplanet orbiting a dead star baffled astronomers. But the planet named WD 1856 b could preview the fate of our own solar system when the sun dies.

While life on Mars (and Venus) has long been an obsession for those wondering if we're alone, there are other places in our solar system that could support life in some form.
