If you only look at one “space photo” this year then this one has to be it. Here it is to download—the Sun, our life-giver, in stunning 83-megapixel glory. You can zoom-in like never before to see close-up its filaments and flares.

Could our universe have been created in a petri dish? Avi Loeb seems to think so. The Harvard astronomer posits that a higher “class” of civilization may have conjured up our universe in a laboratory far, far away.
Life
To become a butterfly, a caterpillar first digests itself. But certain groups of cells survive, turning the soup into eyes, wings, antennae and other adult structures.
