In the early hours of Tuesday (April 23), quadruple solar flares near-simultaneously exploded from across the sun's surface, and there's a good chance that one of these outbursts launched a solar storm toward Earth.

Although astronomers still aren’t quite sure why this happens, it’s certainly observable—and recent activity definitely indicates the sun is heading towards its next “ solar maximum ” later this year.

The Sun, which is now approaching the maximum phase of its solar cycle, surprises with its activity. NASA's Solar Dynamics Observatory scientists have recently observed as many as four solar flares occurring almost simultaneously.

The sun is near the peak of its power, which may explain four solar flares erupting at once. They're no danger to Earth.

NASA’s Solar Dynamics Observatory (SDO) has captured footage of a rare quadruple solar flare eruption. The eruption began around 1 a.m. on Tuesday, April 23. … The post NASA watched four solar flares erupt from the sun at the same time,

The Sun, currently nearing the peak of its solar cycle, has been showcasing some remarkable activity. NASA's Solar Dynamics Observatory has been keeping a close eye and recently spotted an unusual event: four solar flares erupting almost simultaneously.
