What Would Happen If the Sun Ceased to Exist for Just One Second?

If you mean simply "is not visible" then very little, we'd have a second of darkness, not unlike an eclipse, and then we'd be back to normal. If on the other hand, you mean "ceases to exist momentarily" then you're talking about something else entirely. » 9/04/14 12:20pm 9/04/14 12:20pm

Watch a 200,000-Mile Canyon of Fire Rip Open on the Sun

Trying to watch the sun's explosions with your naked eyes is a recipe for blindness, but luckily NASA has a couple of telescopes that can show you all that fusion glory with none of the permanent ocular damage. Take, for instance, this 200,000-mile long canyon of fire. » 10/24/13 1:20pm 10/24/13 1:20pm

We Were Totally Wrong About the Sun's Shape Until Yesterday

For as long as we've bothered to care about heavenly bodies other than our own, we've thought that the size of the Sun varies throughout its 11-year solar cycles.

The Sun Just Had a 79,000 Mile Explosion

You might have had a peaceful day here, but up above, some serious solar violence just went down: an ejection of scorching plasma just erupted from the Sun. Enough to burn its away across ten Earths. » 4/17/12 5:42pm 4/17/12 5:42pm

The fruits of today's Sun UK hack are starting to dangle down: LulzSec (out of retirement?) and Anon are tweeting logins of some serious British media brass. Foremost? Rebekah Brooks, the epicenter of England's voicemail hacking scandal. Update: phone numbers! » 7/18/11 6:25pm 7/18/11 6:25pm

For the First Time In Human History We Have a View of the Entire Sun

Until today, NASA was only able to directly view the Earth-facing side of the Sun. We could see solar storms as they happened, but not necessarily as they developed. Now, thanks to STEREO, we can see all sides simultaneously. » 2/06/11 3:00pm 2/06/11 3:00pm

NASA IBEX Probe Confirms Freaky Stuff Happening at the Edge of Our…

Fact: Space is a freak show. But that link goes to a post about deep space, beyond our solar system. Thanks to the IBEX probe, however, we're quickly learning that our own backyard is rife with the freaky-deaky too. » 10/03/10 12:00pm 10/03/10 12:00pm

When You Love Machines Too Much

Just remember, it could happen to any of us—at any time. Perhaps it will be the draw of soft Barry White playing on our alluring RED Nano, or a particularly revealing angle as Lara Croft illuminates our smooth, curvy, porcelain-white Xbox 360. Indeed, the question is really less "how" than "when". » 3/10/07 3:00pm 3/10/07 3:00pm
