NASA released a shorter animation of the lunar transit that caused a partial solar eclipse last Sunday. Oct. 30.
There's a giant hole growing on the surface of the Sun, but despite its massive size, scientists confirmed that there is nothing to worry about.
Earlier this week, the NOAA's Deep Space Climate Observatory (DSCOVR) satellite reached its orbital position, not circling the Earth or Mars but instead orbiting the Sun itself, at a stunning 1 million miles from Earth.
It's a bit belated, but happy Cinco de Mayo! While citizens in Mexico and the US alike were celebrating Mexico's unlikely victory against French forces in 1862 by throwing parades, singing songs, and enjoying A LOT of tequila, the Sun was having its own kind of celebration. According to NASA, the Sun launched an impressive solar flare on May 5.
Seasons on Earth are determined by how and when our big blue world is tilted towards the Sun. The Sun then, as it is at the center of this process, could not possibly have seasons of its own. Now new research has revealed that this is not necessarily true, for the star actually undergoes predictable swings between times of relative calm and times of intense solar activity.
Just yesterday, while everyone was pinching, pounding down beer, or having an existential meltdown over the truth about shamrocks, people in Northern Europe, Scandinavia, and Iceland got the Northern Lights show of a lifetime. That's because a stunningly powerful solar storm supercharged the auroras in these regions, lighting up the evening sky with some festive colors.
It is known that the Sun plays an important part in controlling the Earth's climate, but now researchers show that solar activity affects climate change more than previously thought, according to recent research.
NASA's Solar Dynamic Observatory (SDO) snapped its 100 millionth image of the Sun since it launched into orbit back in 2010. Now, to commemorate this milestone, a pair of NASA's top scientists involved in the mission selected some of their most favorite images. We've selected the best of those best to share with you.
Despite the "Silent Night" being a mere two days away, on Christmas Eve, all is not calm in space. Our Sun appears to be breaking out its own last-minute holiday lights for the season, erupting in a massive set of solar activity that began just last Friday.
Just last weekend, NASA's Solar Dynamic Observatory (SDO) caught sight of a gigantic dark blemish marring the surface of the Sun. This blemish, called a "sun spot," is the largest seen in this current solar cycle, covering a surface area that could swallow 10 Earth's whole.
Here on Earth, people are gearing up for Halloween with pumpkin carvings, costume shopping and candy cravings, and it seems our Sun wants in on the fun, too. NASA has just released photos of the Sun and its active regions, looking eerily like a toothy grin on a jack-o-lantern's face.
NASA has identified a massive patch of darkness snaking across the surface of the Sun. But don't worry, a giant space-snake has not made its new home so close to Earth. NASA's Solar Dynamics Observatory (SDO) has identified it as an unusually massive and long filament of solar material that is some one million miles across, from end to end.
It's CME week for NASA, and that means the space agency will be pumping out a lot of amazing imagery for the public. That includes a stunning video that shows what Mars may have looked like as it transformed from a watery vista to the desolate and cold planet we see today. One theory even suggests that intense CMEs helped cause this drastic change - a theory that may not be wrong.
Back in Jan. 2005, a massive storm of solar space-weather engulfed the Earth, providing a relatively rare opportunity for scientists to study these storms in the hopes of one day being able to accurately predict their arrival and potential effects on human technology.
