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 flare, designated X2.3, belongs to the most intense X class of flares. It was spotted by Nasa’s Solar Dynamics Observatory, which is constantly monitoring the surface of the Sun in part to ...

Space, with its vastness and beauty, also hides potential threats that could spell disaster for humanity. While many cosmic ...

Solar flares emit radiation, mostly in the form of ultraviolet light and X-rays, that can hurtle toward Earth at the speed of light. Some of these flares can be accompanied by coronal mass ejections, ...

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

A solar flare is a burst of radiation on the sun, according to NASA. They are the most powerful explosions in the solar system, with the biggest ones having as much energy as a billion hydrogen bombs.

Wednesday's X2.7 flare also flung out a coronal mass ejection (CME), a massive explosion of charged solar plasma, which are often thrown from the sun's surface at the same time as a solar flare.

Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of ...

Sunspot AR3767 erupted with a X1.7-class solar flare on Aug. 5, 2024. It was quickly followed by an X1.1-class flare from sunspot AR3780. NASA's Solar Dynamics Observatory captured the fireworks.

In the blazing upper atmosphere of the Sun, a team of scientists have found new clues that could help predict when and where the Sun’s next flare might explode.

Several M-class solar flares erupt within just a few hours late Dec. 25. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Solar flares measured around X1 — like the May 13 and 14 events — indicate strong flare intensity. An X10 flare is described as as a severe event, according to NOAA.
