Christopher Go of Cebu City Phillipines managed to catch an incredible transit of Io’s shadow over Ganymede. These are 2 of the moons of Jupiter aka the Jovian moons. This is a very difficult series to actually catch.

We have seen many amateur astronomers in the news lately. Earlier this year Australian amateur astronomer Anthony Wesley captured an image showing the impact scar left on Jupiter by an apparent comet. Then in late 2008 a ninth-grader in NY named Caroline Moore discovered a supernova as an amateur. So this just adds to the list of things amateur astronomers are doing to further the field of astronomy with their own equipment and time.

Jupiter Gets It In The Eye!

Many places are reporting today that yes indeed amateur astronomer Anthony Wesley discovered that Jupiter was hit by something rather large. In 1994 comet Shoemaker-Levy 9 hit Jupiter with spectacular results. In this image by Mr. Wesley the dark spot at the top of the image isn’t normally seen. It was clearly something new and different and it turns out to be an impact.

Now there are professional astronomers adding more observations with more sophisticated equipment but this is the discovery of a lifetime for an amateur astronomer so congrats to Anthony Wesley of Murrumbateman Australia.

The NASA Infrared Telescope Facility in Hawaii took this image which shows not only the impact area but the debris scattered in the upper atmosphere. Check out the post over at Universe Today for more information.
