Solar déjà vu.

The large sunspot that rotated out of view about two weeks ago has returned. Though much reduced in size, it did blast a good-sized coronal mass ejection about a week ago on the far side of the Sun. It was showing off numerous magnetic loops and arches above it as it came into view. We’ll be keeping an eye on this one for more solar activity. Sunspots can last from days to months, so for it to return again is not an unusual event. Credit: NASA/SDO

Astronomers took this image as they were observing an extraordinary exploding star – a supernova – near the galaxy’s central yellow core! The star rapidly evolved from a supernova containing very little hydrogen to one that is hydrogen-rich — in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. By studying similar galaxies we hold a scientific mirror up to our own, allowing us to build a better understanding of our galactic environment, which we cannot always observe, and of galactic behavior and evolution as a whole.
