Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses.

A solar storm is a catchall term that describes any disturbance in the sun that involves the violent ejection of solar ...

Webb Telescope finds crystalline water ice around star HD 181327. This discovery could reveal how icy bodies contribute to ...

Early on Tuesday, Feb. 26, a rare annular solar eclipse created a “ring of fire” over Antarctica, while South Africa and Indian Ocean locations saw partial phases.

A stunning “ring of fire” eclipse was totally visible to a lucky few in the Southern Hemisphere. Here’s how to see the next one ...

The next visible solar eclipse in North America is expected on August 12, 2026.

An annular solar eclipse occurs when the moon passes between the sun and the Earth without completely covering the sun.

This hypothesis has the advantage of explaining why the rings have a lot of ice and little rock, in contrast to models where a moon strayed inside Saturn’s Roche limit and was pulled apart.

Astronomers have reported one of the longest stellar dimming events ever recorded, with a Sun-like star fading by 97 percent for nearly 200 days. Astronomers believe one of the longest stellar dimming ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...
