The "Peony Nebula," as discovered by NASA's Spitzer Space Telescope. This three color infrared composite shows 3.6-micrometre light in blue, 8-micrometre light in green, and 24-micrometre light in red. The Peony nebula is the reddish cloud of dust in and around the white circle, surrounding the Peony nebular star.
Nebulae, Abell 33. This image was made by BABlog regular Adam Block, using the 0.8 meter (32") Schulman Telescope at the Mount Lemmon SkyCenter. He combined images through four filters for a total observation of 630 minutes, over ten hours, to make this dream-like shot.
