Four X-Class Flares In Two Days Highlight The Arrival Of The Sun's Solar Maximum [Video]

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.

Earth's Core Temperature Comparable To The Sun's Surface, Study Says

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.

Saturn's Rings Are As Old As Our Solar System And Gave Birth To Prometheus

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.

Voyager 1 Leaves Solar System And Enters Interstellar Space...Or Does It?

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 Films Amazing Plasma 'Rains' on Sun (VIDEO)

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.

IBEX Ribbon Around Our Solar System Caused By Re-Charged ENAs, New Study Says

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's Corona Has A Hairstyle, And It's Some Really Hot 'Braids' (VIDEO)

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.

Massive Solar Eruption 20 Times Earth's Diameter Recorded By NASA On New Year's Eve (Video)

A solar eruption the size of 20 Earths was captured on camera by NASA's Solar Dynamics Observatory on Monday.

Ignited Comet to Pass Earth at End of 2013 for the First Time in Over 300 Years

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 'Gusty' Turbulence That Helped Shape Our Universe Measured For First Time

Cosmic turbulence can play a major role in astrophysical events, but has never been measured, until now.

'We Must Know More About The Sun And Its Weather Patterns,' Say Scientists

A report compiled by 85 scientists about scientific goals over the next decade puts a great deal of emphasis on understanding the sun better.

Predicting Solar Flares On The Horizon (VIDEO)

A pair of scientists have figured out that radioactive decay might provide clues to when powerful solar flares might erupt from the sun.
