On the left is Spitzer's view of the supernova on three separate dates: May 9, 2005; Feb. 7, 2014; and Feb. 12, 2014. The observations from February 7 reveal the presence of a bright spot -- the supernova -- not present in the prior observations. By Feb. 12, the supernova has started to dim somewhat from its peak brightness in the first week of February. The supernova is glowing very brightly in the infrared light that Spitzer sees. The telescope was able to observe the supernova before and after it reached its peak brightness. Such early observations with an infrared telescope have only been obtained for a few Type Ia supernovas in the past.
On the right is the supernova seen by Hubble on Jan. 31, 2014 as the supernova approached its peak brightness. The Hubble image was taken in visible light with Hubble's Wide Field Camera 3.

On the morning of Saturday, Feb. 22, the Moon drifted in front of the planet Saturn from the point of view of certain locations on Earth. Luckily one of those locations was Perth, Australia, where astrophotographer Colin Legg happens to be, and thus we all get to enjoy the fantastic results of his photographic and astronomical acumen.
