A schematic of how polar rain aurora occurs, with electrons streaming out of a coronal hole on the sun. (Image credit: Science Advances (2024). DOI: 10.1126/sciadv.adn5276) ...

For decades, scientists have struggled to see the outermost layer of the Sun, called the corona, with enough detail to unlock ...

The team’s imaging breakthrough hinges on a technology called coronal adaptive optics. Installed on the 5.25-foot (1.6-meter) Goode Solar Telescope in California, the new system—nicknamed ...

Rain, unlike the sun, is neither inherently good nor inherently bad. Desalination plants and drip irrigation aside, the Land of Israel still needs rainwater in order for crops to grow.

Newly released imagery from NASA shows the Sun's corona in stunning detail after the Parker Solar probe performed its closest-ever flyby.

These bursts of electrically charged gas can blow off the sun and reach all the way to Earth, affecting satellites and power grids. The moon eclipses the sun on April 8, 2024.

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond during the long days of summer.

In six billion years the sun will expand into a red giant. That process should consume Mercury, and maybe Venus. For a long time we have thought it might incinerate Earth, too.. But perhaps all is ...
