During the latter part of last week, a huge void rotated across the face of the sun. But never fear, it isn’t a sign of the “End Times” or some weird sci-fi stellar malnourishment, this particular hole is a coronal hole. Though it may be a well-known phenomenon, it is noteworthy — it’s the largest coronal hole to be observed in the sun’s atmosphere for over a year. Read more
Three years ago, on Feb. 11, 2010, NASA’s Solar Dynamics Observatory (SDO) was launched into orbit to begin its solar odyssey. Intended to give us the most high-definition view of the sun to date, the SDO has transformed our understanding of our nearest star. Browse our celebratory gallery
At 11:12 UT (6:12 a.m. EST), the world didn’t end (as far as I can tell), but it was a significant time none-the-less … The ever-watchful NASA Solar Dynamics Observatory (SDO) captured the time of solstice from orbit. Although the SDO is always imaging the sun through a multitude of filters, this is a great excuse to showcase the fantastic beauty of our nearest star, while putting all the doomsday nonsense behind us.
It seems likely that AR1618 flare activity will continue through Thanksgiving, and if you live at high latitudes, you may be lucky enough to see some Thanksgiving Day aurorae. The sun is currently bathing our planet in a moderate-speed stream of solar wind. Although a full-blown geomagnetic storm isn’t expected, there’s a chance of some heightened auroral activity near the Arctic Circle.
Giant Sun Eruption Captured in NASA Video: The sun unleashed a monster eruption of super-hot plasma Friday (Nov. 16) in back-to-back solar storms captured on camera by a NASA spacecraft.
The Sun is having a party… and it looks like we’re invited! Eek!
Continuing its increasingly active trend, the sun erupted with an X-class solar flare on Thursday. Only last week, another active region (AR1515) delivered an impressive parting shot — an X1.1 flare — as it rotated toward the solar limb. Today’s more energetic X1.4 flare however was directed right at us.
