A distant gas giant the size of 10 Jupiters is now the first planet outside Earth's solar system to be mapped in three ...

A newly detected super-Earth just 20 light-years away is giving scientists one of the most promising chances yet to search ...

This eruption was a Coronal Mass Ejection, or CME. These events are huge blobs of plasma (highly ionized gas) and magnetic fields that rip away from the Sun’s outermost layer of atmosphere.

The team identified planets around three stars, including TOI-5799c, which may have an atmosphere and conditions suitable for liquid water.

Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...

The milestone highlights the accelerating rate of discoveries, just over three decades since the first exoplanets were found. The official number of exoplanets — planets outside our solar system — ...

A University of Arizona-led team discovered a growing planet, WISPIT 2b, forming inside a disk gap around a young star. The finding confirms theories that protoplanets carve out gaps in disks of gas ...

Astronomers have, for the first time, detected a massive explosion from a star outside our solar system, specifically a ...

Space is still the final frontier, and NASA has announced that the frontier is more vast than we realized. The NASA Kepler mission has discovered 715 planets set up in multiple-planet systems a lot ...

As telescopes have become more powerful, it’s turned out our solar system is not the only game in town: There are millions of ...
