Massive sunspot just like the one that caused the 1859 Carrington event is pointing right at Earth!
A new sunspot complex, AR 4294-4296, has recently appeared on the Sun, drawing attention due to its size and potential for powerful solar flares. According to Spaceweather.com, this sunspot is ...
Sunspots AR3664 and AR3663 have been erupting with X- and M-class solar flares. Both sunspots are Earth-facing and could ...
Observing an eclipse of the sun is always fascinating, but on March 29, 2025 — when a partial solar eclipse is visible in the Northern Hemisphere — there will be an extra reason to do so. As well as ...
Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...
Large cluster of sunspots that can cause strong solar flares and affect power grids detected by NASA
NASA has detected a large grouping of sunspots — dark patches on the sun — known as AR3576, which have increased in size in the last month and could be a risk for strong solar flares. Solar flares, ...
Astronomers have detected a massive group of sunspots being referred to as a "sunspot archipelago." The group is made up of at least six different sunspots, and astronomers warn it could spell trouble ...
German astronomer Johannes Kepler made sketches of sunspots in 1607 from his observations of the sun’s surface — and centuries later, the pioneering drawings are helping scientists solve a solar ...
Sunspot AR3590, which recently spit out three X-class solar flares in under 24 hours, has grown even larger and is now pointed almost directly at Earth, putting us in the crosshairs of more potential ...
BOULDER–Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun’s impact on Earth over the course of the 11-year solar ...
A whopping sunspot that is getting larger and crackling with activity threatens to flash powerful solar flares in our planet's direction. The sunspot, named AR3780, appears to be getting bigger and ...
On May 29, 2020, a family of sunspots — dark spots that freckle the face of the Sun, representing areas of complex magnetic fields — sported the biggest solar flare since October 2017. Although the ...
