Using NASA's James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way.

The Sun’s activity cycle continues to stir things up, as our star recently unleashed a massive X-class solar flare that was strong enough to cause radio blackouts across the south Pacific.

The Origin of the Sun's Magnetic Field Could Lie Close to Its Surface May 22, 2024 — Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's ...

Scientists have developed an AI model that accurately predicts solar flares and coronal mass ejections, significantly ...

For example, consider May 10 and 11, 2024, when dozens of solar flares sent at least five coronal mass ejections (CMEs) toward Earth. “The CMEs merged, amplifying one another, to create a major ...

Solar flares are violent outbursts of electromagnetic radiation that shoot from the sun when invisible magnetic field lines at the sun's surface get twisted up until they eventually snap. These ...

a repeating crescendo of solar activity that often comes with increased solar flares. True to form, it seems like there's another flare every few days. Rapid-fire solar flares have been lighting ...

What is space weather, what causes it, and how does it affect humans? Physicist Robyn Millan, who co-chaired a recent National Academies decadal report on solar and space physics, answered questions ...

On a hot and humid Florida night in late August 1859, the sky suddenly lit up. But it was not from fireflies or a fireswamp. Instead, it was the Northern Lights–or aurora borealis. The aurora is ...
