A total solar eclipse is seen from San Millán de los Caballeros, Spain, Wednesday, Aug. 12, 2026. A total solar eclipse – the Moon passing between the Sun and Earth, completely blocking the face of the Sun – swept across parts of Greenland, Iceland, northern Russia, the Atlantic…
One of nature's greatest spectacles—a rare total solar eclipse—cast its shadow on Wednesday, briefly turning day into night in Russia's remote Arctic north and western Iceland before heading toward mainland Europe.
Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.
Scientists using the Daniel K. Inouye Solar Telescope (DKIST) in Hawai'i have found a mechanism occurring on the Sun's surface that they think is heating our star's outer atmosphere. The process, called a Kelvin-Helmholtz Instability (KHI), could well be the root cause of a…

An international team of researchers using the U.S. National Science Foundation's Inouye Solar Telescope has captured the highest-resolution view of the sun's surface.
A total solar eclipse and the northern lights at the same time? Experts explain why it's possible, but the odds are stacked against it.
A naked-eye view of the sun's outer atmosphere is the reason eclipse chasers travel the world. Here's what it may look like on Aug. 12.
The Inouye Solar Telescope has captured the highest-resolution images of the sun's surface yet. They show instabilities that may help explain the hot surface. The post Highest-resolution images of the sun’s surface here! first appeared on EarthSky .
Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun’s surface, some just 20 kilometers wide. These previously invisible vortices may twist magnetic fields and help build up the energy released in small solar eruptions called nanoflares. They may…
A brilliantly simple grab-and-go solar mount that finds and follows the sun for you, Sky-Watcher’s SolarQuest is perfect for small-scope solar astronomy and solar eclipses.
Solar observation is easy with a smart telescope like the Unistellar eQuinox 2 and the matching filter, meaning you can capture it with no stress on big events like the Aug. 12 total solar eclipse.
In twilight, watch bold Venus and tiny Spica approach each other to meet September 1st. And check whether you'll be able to see anything of Wednesday's solar eclipse!
Video: 00:01:44 [English] On 12 August 2026, Europe will witness one of nature’s most spectacular events: a total solar eclipse starting at 19:30 CEST. As the Moon’s shadow sweeps across Spain, join the European Space Agency live from Observatorio Astrofísico de Javalambre where…
On the evening of 12 August 2026, the Moon will pass between Earth and the Sun, producing a striking solar eclipse. Find out how, when and where to observe it safely.
It’s almost show time. We’re just a few days away now, from the only total solar eclipse of 2026. While eclipses are a surety as the celestial gears of the Universe grind on, there are always a few unknowns leading up to eclipse day. We wrote a recent guide to the upcoming total…
Several science campaigns plan to greet the racing shadow of the Moon on August 12th.
Picture reveals tiny plasma whirlpool-like patterns that have never been seen before
A total solar eclipse is coming to Europe. The European Space Agency (ESA) will broadcast live from 19:30 CEST on 12 August, allowing you to experience this rare event from anywhere in the world. Quick links: - Live ESA broadcast on YouTube (12 August, 19:30–20:45 CEST) - Event…
The August 12th total solar eclipse in Europe gives North Americans a partial view.
Citizen scientists from the Dynamic Eclipse Broadcast Initiative recorded nearly an hour of coronal behavior during the 8 April 2024 solar eclipse.
A new analysis suggests the Sun holds far more silver than earlier estimates indicated. More advanced models of the solar atmosphere raised the calculated amount by 55 percent, bringing it into much closer agreement with ancient meteorites. The technique may also help scientists…

Hanya Pan et al 2026 ApJ 1001 89 Researchers show a connection between non-thermal hard X-ray emission and a tadpole-shaped downflow, strengthening the association between these flows and magnetic reconnection.
China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar…
A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the…
