What's more fun than something that misbehaves? When it comes to solar dynamics, we know a lot, but there are many things we don't yet understand. For example, when a particle filled solar flare lashes out from the Sun, its magnetic field lines can do some pretty unexpected things – like split apart and then

... team of astronomers led by Jose Dias do Nascimento (Department of Theoretical and Experimental Physics, Universidade Federal do Rio Grande do Norte [DFTE, UFRN], Brazil) has found the farthest known solar twin in the Milky Way Galaxy-- CoRoT Sol 1, which has about the same mass and chemical composition as the Sun. Spectra from the High Dispersion Spectrograph (HDS) on the Subaru Telescope showed that CoRoT Sol 1 is about 6. 7 billion years old while space-based data from the CoRoT (Conve

... May 14, 9 a. m. EDTThe sun emitted a third significant solar flare in under 24 hours, peaking at 9:11 p. m. EDT on May 13, 2013. This flare is classified as an X3. 2 flare. This is the strongest X-class flare of 2013 so far, surpassing in strength the two X-class flares that occurred earlier in the 24-hour period. The flare was also associated with a coronal mass ejection, or CME. The CME began at 9:30 p. m. EDT and was not Earth-directed. Experimental NASA research models s

The Sun gets active! On May 12, 2013, the Sun emitted what NASA called a significant solar flare, classified as an X1. 7, making it the first X-class flare of 2013. Then earlier today, May 13, 2013, the Sun let loose with an even stronger flare, an X2. 8-class. Both flares took place just beyond the limb

Destination EarthCopyright: SOHO (ESA/NASA)/S. Hill Solar science meets art in this unique portrait of a solar storm heading straight for Earth. The image is based on data collected by the ESA/NASA SOHO space observatory during a coronal mass ejection, when a huge cloud of magnetised plasma was ejected from the Sun's atmosphere and launched towards Earth. The image shows an extreme-ultraviolet view of the solar disc superimposed on a wide-field view of the surrounding solar

Just in time for May Day, the Sun blasted out a coronal mass ejection (CME) from just around the limb earlier today, May 1, 2013. In a gigantic rolling wave, this CME shot out about a billion tons of particles into space, traveling at over a million miles per hour. This CME is not headed

We live on a planet dominated by weather. But not just the kind that comes in the form of wind, rain, and snow — we are also under the influence of space weather, generated by the incredible power of our home star a “mere” 93 million miles away. As we orbit the Sun our planet

Over the past 24 hours, the Sun has erupted with two coronal mass ejections (CMEs), sending billions of tons of solar particles into space. While these CMEs are not directed at Earth, they are heading towards Mercury and may affect the Messenger spacecraft, as well as the Sun-watching STEREO-A satellites. One CME may send a
