Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf ...

This giant protective bubble, created by the Sun’s solar wind, extends far beyond the orbit of Neptune and shields life in our solar system from harmful cosmic radiation and high-energy particles.

Importantly, the 6,000 figure is continuously updated as astronomers around the world confirm new planets, meaning no single planet is officially the 6,000th.

Sub-Neptune exoplanets tend to be much closer to their host star than Earth is to the Sun and are thought to have atmospheres made of steam over layers of an exotic phase of water that behaves like ...

3I/ATLAS, an interstellar object currently zipping through the solar system, is capturing the attention of astronomers, the public and even most of our deep space assets. Its hyperbolic orbit tells us ...

Discovery: On July 2, 2025, astronomers confirmed Comet 3I/ATLAS, marking only the third interstellar object (ISO) ever detected passing through our Solar System, after 1I/ʻOumuamua (2017) and ...

What lies beyond Neptune? Is it just empty space… or something far more mysterious? In this video, we explore the fascinating story of the Oort Cloud – a gigantic, icy sphere that surrounds our Solar ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

A new image has revealed the clearest glimpse yet of an interstellar visitor zipping through our solar system. The Hubble Telescope and its Wide Field Camera 3 got an incredible view of the comet ...
