Solar Fireworks


This movie shows fireworks on the Sun as seen in UV by the Solar Dynamics Observatory while 10 significant flares erupted on the sun from 19 through 28 October. The graph shows X-ray output from the sun as measured by NOAA’s GOES spacecraft. The X-rays peak in sync with each flare.

The Eye of Jupiter


jupitereye_0Not really. The trick is that the planet seems to be looking back at us because Hubble happened to catch the shadow of Ganymede, Jupiter’s largest moon, as it moved across the Giant Red Spot. Hubble was monitoring changes in that huge storm last April when the moon’s shadow moved across the center of the storm. For a moment, Jupiter became Cyclops.
