The sun is beginning a new weather cycle, causing debate among scientists about how intense things are going to get, and elsewhere, scientists are looking into just how fluid our early universe was.

When sunspots erupt at nearly the same time, it could be something known as "sympathetic solar flares." A double eruption from sunspots AR3614 and AR3615 may be an example of it.



One of the flares was an X1-class flare and...

Dive into 'Sun Spots' to uncover the mysteries of those dark patches on our brilliant Sun and what they tell us about solar activity! A quick, illuminating look into the sun’s secrets, perfect for young space explorers.

This video is answering the question of how hot are Sun Spots.

The Solar Dynamics Observatory is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously. Dean Pesnell,...

The Sun is a star, made of trillions upon trillions of tons of ionized gas, called plasma. That's a little hard to make at home, so our version trades in helium and hydrogen for butter and sugar! For these...

The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on Feb. 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a...

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames...

An X1.4 class flare erupted from the center of the sun, peaking on July 12, 2012 at 12:52 PM EDT. It erupted from Active Region 1520 which rotated into view on July 6.
