A hot Jupiter exoplanet's comet-like tail is far longer than previously thought, spanning at least 350,000 miles, scientists say.

The first close-up images of the gigantic star RW Cephei explain why it appeared to mysteriously grow dimmer in recent years before brightening once more.

The mysterious wispy green light captured by the James Webb Space Telescope last year near the heart of Cassiopeia A turns out to be a result of a blast wave slamming into surrounding material.

Europe will launch two satellites in September which will together form an artificial eclipse to help scientists study the sun.

A fresh analysis of Voyager 2's images of Uranus and Neptune reveal the two ice giants are similar shades of blue.

To combat increasing global temperatures, scientists have developed a new cooling glass paint which effectively uses space as a heat sink.

The recently detected gravitational waves are a muddled mix of various sources, new study finds.

These are the James Webb Space Telescope's most notable discoveries in 2023.
