Scientists at NASA are gearing up to observe the sun as the magnetic fields of its poles begin to switch.
NASA now has the most comprehensive video of the process that creates explosions on the Sun and affects space weather.
NASA's IBEX telescope gives astronomers a view of the solar system's tail.
NASA has announced that preparations are underway to launch the IRIS Mission in order to study the solar atmosphere.
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.
