SDO has roughly two 'eclipse seasons' per year, and is currently in its 31st since the mission launched. It begain on July 10 ...

NASA's Solar Dynamics Observatory captured sunspot AR3386 blast a long-duration X1.6-class solar flare and X1 flare. See time ...

In the span of two days last week, the sun released two strong solar flares — meaning the solar system experienced its most powerful explosions which can cause some communications blackouts on Earth, ...

The Solar Dynamics Observatory saw a lunar transit and an Earth eclipse on July 25 — the first when the moon passed between ...

The latest solar flare follows an M-class one, the second-highest on the scale, that occurred days earlier on June 15. It caused a shortwave radio blackout across North America, with a loss of signal ...

Solar flares can last mere minutes or can drag on for hours, depending on their intensity. NASA classifies solar flares based on their strength, with A-class the smallest and X-class – which is what ...

On July 18, NASA successfully launched a sounding rocket mission from the White Sands Missile Range in New Mexico, carrying a ...

When sunspots erupt at nearly the same time, it could be something known as "sympathetic solar flares." A double eruption ...

The flare on May 13 was classified as an X1.2 flare, while the following day's event was listed as an X2.7 flare — the number provides more information about the event's strength, according to NASA.

NASA says they captured a massive solar flare erupting from the sun. In a blog post, the space agency said the solar flare occurred Wednesday, peaking at 1:35 p.m. EST.

It was an X-class flare — the most intense kind, NASA said. Solar flares are essentially "giant explosions on the sun" that send energy, light and high-speed particles into space, according to NASA.

NASA’s Solar Dynamics Observatory captured this image of coronal loops above an active region on the sun in mid-January 2012. The image was taken in the 171 angstrom wavelength of extreme ...
