The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down. ...
The photo was taken on February 6, NASA says, and is the first time that the sun rays, also known as crepuscular rays, have been viewed so clearly. The Curiosity Rover shared the image to itsTwitter pageand it was taken as part of the rover’s twilight cloud survey. ...
