New footage from NASA shows what the Sun looks like over the course of three long years.
You don't need an expensive DSLR and a huge lens to capture high-resolution photos of the sun like these.
If Mars was hoping to steal all our attention this week it almost worked. That was until photos surfaced taken on August 5, 2012 of a dark colored filament on the Sun that stretched almost 800,000 kilometers (or 500,000 miles) in length — twice the distance from the Earth to the Moon.
Did you catch yesterday's annular solar eclipse? I wasn't on the Western hemisphere to see it. Luckily, there are photographers like Cory Poole who did a fine job capturing the "Ring of Fire." Poole's timelapse of the entire eclipse might just be one of the best out there.
It's five times the size of the Earth! If the size of this solar tornado doesn't scare the pants off you, the temperature of it should. This solar twister is made from gas ranging from 90,000 to 3.6 million degrees Fahrenheit.
Solar sails harness the pressure of the solar wind to propel spacecraft across the solar system essentially for free, without the need for engines or fuel. An electric solar sail works more or less the same way, except without the sail: all you need are a bunch of wires.
Sunspots, often the precursors to gigantic solar flares that can potentially destroy our entire planet in an instant (well, nearly), can now be accurately predicted two days ahead of when they emerge on the sun's surface. So relax, you'll have plenty of time to put on your tinfoil hat and prepare for the apocalypse.
See that? That gigantic solar explosion just barely missed the Earth. You probably didn't need to head to your nearest bomb shelter (you do know where your nearest bomb shelter is, right?), but here's some of the effects that solar storms can have on our planet.
This ultraviolet image of the sun, courtesy of the NASA Solar Dynamics Observatory (SDO), is helping scientists better understand violent solar outbursts. These eruptions are sometimes so powerful they disrupt Earth's global positioning systems and electrical grids....
The entire sun experienced a series of violent explosions back in August. And thanks to a new sun-observing satellite, NASA captured the whole thing. Not only are the images amazing, but they also helped researchers determine that solar activity occurring simultaneously may not always be a coincidence.
