Got over 4"'s of rain and HOWLING winds thru the night. Hope the sky clears so I can get the 'scope out.
Hubble Space Telescope (HST) has been monitoring the planet Jupiter for years and the latest image confirms that the "Great Red Spot (GRS)" - a striking feature that has existed for centuries on Jupiter is shrinking.
HST's latest observation of GRS confirms that it is now the smallest size ever recorded and is about half of the size measured in historical telescopic observations.
In the late 1800's the GRS was about 3 times the diameter of our planet!
With the arrival of NASA's Juno spacecraft at Jupiter in July 2016 we will be able to study the GRS up close and personal and maybe find out what is causing this historic shrinkage.
