This newly released Hubble image shows spiral galaxy Messier 65.
The 1st of March 1780 was a particularly productive night for Charles Messier. Combing the constellation of Leo for additions to his grand astronomical catalog, he struck on not one, but two, new objects.
One of those objects is seen here: Messier 65. “Nebula discovered in Leo: It is very faint and contains no star,” he jotted down in his notebook. But he was wrong — as we now know, Messier 65 is a spiral galaxy containing billions upon billions of stars.
All Messier saw was a faint diffuse light, nothing like the fine detail here, so we can forgive his mistake. If he had had access to a telescope like Hubble, he could have spied these stunning, tightly wound purple spiral arms and dark dust lanes, encircling a bright center crammed with stars.
Almost exactly 233 years later in March of this year, one of the stars within Messier 65 went supernova (not seen in this image), rivaling the rest of the entire galaxy in brightness. This, the first Messier supernova of 2013, is now fading, and the serene beauty of M65 is returning.
A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.
