Yes, that's right, there's a hole in the sun, but it's not a sign of anything scary, it's actually a wonderful insight to some pretty 'cool' solar dynamics.
In 'The Martian', Mark Watney deals with a lot of dangerous situations -- food and communications being a couple of them. But what if his camp got hit by a solar storm? How could he protect himself?
Finally, we have proof of the moon's 'noble' heritage!
As Comet 67P/Churyumov-Gerasimenko approaches perihelion, the sun is heating up its nucleus and the solar wind is causing its tail to evolve. And the Rosetta mission has a ringside seat.
For the first time, astronomers have detected an aurora erupting beyond the solar system, giving us a profound glimpse at the magnetism surrounding a brown dwarf, or 'failed star.'
Not only has NASA’s New Horizons mission confirmed that Pluto has an extended atmosphere, after its historic flyby on July 14, the spacecraft observed a “cavity” in the solar wind, revealing a long plasma tail reminiscent of a comet’s ion tail.
Pluto may be, on average, 40 times further away from the sun than Earth, but that doesn't mean it doesn't experience the sun's outbursts.
A giant eruption from the sun that scientists thought would hit Earth in 2014 missed because the sun's magnetic field channeled it away from the planet in an unexpected way.
