Looks like things are really heating up. In a rare 2013 display of its immense power, the sun unleashed four massive X-class solar flares upon our solar system over the matter of two days, highlighting the arrival of its solar maximum.
A recent study from scientists at France's CEA research agency reveals that the Earth's core is as hot as the Sun's surface. According to the study, the temperature of the Earth's core is measured at 6,000 Celsius, a range on par with the temperature with the Sun's surface.
A new fine-toothed examination of NASA's Cassini spacecraft's observations of Saturn has revealed that its breathtaking rings are "vintage goods" stemming from our solar system's birth, and are actually the origins of one of Saturn's moons.
For a while, it looked like Voyager 1 might have hit another milestone in space exploration - interstellar space - but a revised outlook states there's still some ways to go. The probe, launched by NASA back in 1977, is indeed still in our solar system, NASA has stated.
NASA released a spectacular video on Wednesday that was captured by a sun-watching spacecraft and shows loops of superheated plasma raining down on the sun's surface.
A mystical ribbon of particles surrounds the region of space between our solar system and interstellar space. Known as the edge of the heliosphere, it has baffled scientists as to what the nature and cause of such a cosmic phenomenon could be. A newly proposed "retention model" suggests that the ribbon is the result of charged particles escaping as neutral atoms.
The sun - giver of life, light bulb in the sky, and head honcho of our solar system - exhibits an extremely odd characteristic: it's actually hotter as you move away from the surface. Scientists may have finally understood a key piece to this puzzle by studying the sun's corona in unprecedented detail.
A solar eruption the size of 20 Earths was captured on camera by NASA's Solar Dynamics Observatory on Monday.
On New Years' Eve in 2013, if you look to the night sky, you may see a comet barreling past earth, glowing brighter than a full moon.
Cosmic turbulence can play a major role in astrophysical events, but has never been measured, until now.
A report compiled by 85 scientists about scientific goals over the next decade puts a great deal of emphasis on understanding the sun better.
A pair of scientists have figured out that radioactive decay might provide clues to when powerful solar flares might erupt from the sun.
