Equinoxes

Today is the Fall Equinox…and its finally in the 60’s at night here!  Just in time for our Equinox, Cassini has released a spectacular image of Saturn taken on its recent equinox.

This is not one picture, but a mosaic of 75 images taken by Cassini!  Download the full 7227×3847 image if you dare!

Saturn takes a lot longer to go around the Sun, so it’s equinoxes occur about every 15 years.  The rings are almost edge on to the Sun, so they are not brightly illuminated.  Cassini was out of the ring plane when it took this picture so we get a nice view looking “down” on the rings.  They released some other images as well you can check out.

Just for good measure, the New York Times profiled the head of the Cassini Imaging Team, Carolyn Porco. I have met her a few times and she gives great Saturn talks.
