Solar Minimum is becoming very deep indeed.
A newly found asteroid has been spotted orbiting the Sun, whizzing past the star every 151 days, the shortest orbit of any space rock on record.
It’s one of the greatest and longest-running mysteries surrounding, quite literally, our sun — why is its outer atmosphere hotter than its fiery surface?
The sun’s magnetic field is ten times stronger than previously believed, new research from Queen’s University Belfast and Aberystwyth University has revealed.
Before coronal mass ejections, plasma shoots up, breaks apart and then comes together again.
In this July 6, 2018 file photo, NASA’s Parker Solar Probe sits in a clean room at Astrotech Space Operations in Titusville, Fla., after the installation of its heat shield. Parker has made its first close approach to the sun, just 2 1/2 months after liftoff. The spacecraft flew within 15 million miles (24 million kilometers) of the sun’s surface Monday night, Nov. 5. Its speed topped 213,000 miles (342,000 kilometers) an hour relative to the sun, as it penetrated the outer solar atmosphere, or corona. No spacecraft has ever gotten so close to our star.
