National Large Solar Telescope

The Sun is the harbinger of life on Earth, but we understand so little of our nearest star. The Sun occasionally gets very angry; it then unleashes massive solar storms that take down or burn satellites and electronic equipment on Earth.

American space agency NASA on Sunday shared the "largest-ever" image assembled of the Andromeda galaxy by the Hubble Space Telescope. The picture was captured seven years ago and it is the sharpest large composite image ever taken of the galaxy.
