It’s actually a massive, raging storm in Jupiter’s northern hemisphere. The bright clouds and their shadows range from approximately 4 to 8 miles in both widths and lengths. These appear similar to the small clouds in the other bright regions our Juno spacecraft (@NASAJuno) has detected and are expcted to be updrafts of ammonia ice crystals possibly mixed with water ice. This image was captured on Oct. 24 at 10:32 a.m. EDT by our Juno spacecraft during its ninth close flyby of the gas giant planet. Credit: NASA/JPL-Calthech/SwRI/MSSS/Gerald Eichstädt/Seán Doran
This edge-on view of a galaxy located about 45 million light-years away, showcases its beautiful arms, which swirl like a whirlpool around its bright central region.

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.
