Researchers at the University of Hawaiʻi have usedrare total solar eclipses to gain unprecedented insights into the turbulent ...

NASA’s Parker Solar Probe has spent the past year repeatedly diving into the sun’s outer atmosphere at speeds no human-made ...

NASA’s Parker Solar Probe has completed a historic milestone by traveling closer to the Sun than any spacecraft before it. The groundbreaking data it has collected is offering new insights into the ...

On February 17, 2026, an annular solar eclipse occurred, offering a spectacular view of the “ring of fire” in the sky. The European Space Agency (ESA) captured this rare cosmic event from space ...

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.

The Sun fired off six X-class flares in the first four days of February 2026, a burst of extreme activity spanning roughly 400,000 miles of the solar disk. That stretch covers nearly half the Sun’s ...

To study the sun, scientists use a specialized telescope called a coronagraph. This instrument mimics a solar eclipse by using a occulting disk to block out the sun's bright light. By doing this, ...

In early September 2025, skywatchers in parts of the Eastern Hemisphere were treated to a total lunar eclipse as Earth blocked the sun's light from the moon. The eclipse occurred in the evening of ...

Close-up measurements from NASA’s Parker Solar Probe are giving scientists an unprecedented look at how the solar wind gains ...

Coronagraphs are telescopes equipped with an occulting disk to block out the overwhelming radiation emanated from the visible surface of the Sun, along with optical stops and filters that are ...
