A new camera called the One Degree Imager, located at Kitt Peak National Observatory in Arizona, is responsible for this enticingly crisp image of the Bubble Nebula. Released on December 4, this closeup highlights the sphere of gas blown out by the nebula’s central star, which is 45 times larger than our own sun.
Located in the constellation Cassiopeia, the Bubble Nebula is ten light-years across. Intense radiation from the massive star causes the otherworldly glow that lights up what looks like a celestial soap bubble.
IC 2810 is a disk galaxy viewed nearly edge-on. It is slightly disturbed by gravitational interaction with a smaller, dusty companion (located to the bottom of the image). The larger galaxy shows blue knots of star formation. Although the pair has no overlapping region at present, it is possible that the two will eventually collide in the future. IC 2810 is located in the constellation of Leo, the Lion, about 450 million light-years away.
The Hubble Space Telescope has been looking deep into the Cosmos for over two decades returning over a million observations of planets, exoplanets, nebulae, galaxies and clusters of galaxies. The mission has surpassed our wildest expectations, but some of the most intricately beautiful views of the Universe have been released only recently — sometimes in collaboration with other observatories.
“This is a composite of all the Geminid meteors captured over Pendleton, Oregon on the evening of December 13, 2012. I took these from Emigrant Hill. In the valley below, you can see the light “footprint” of Pendleton, Mission, the Wildhorse Casino, and several other smaller towns. Fog has enveloped most of the cities below.”

Seen as a seagull and a duck, these nebulae are not the only cosmic clouds to evoke images of flight. But both are winging their way across this broad celestial landscape, spanning almost 7 degrees across planet Earth’s night sky toward the constellation Canis Major. The expansive Seagull (upper left) is itself composed of two major cataloged emission nebulae. Brighter NGC 2327 forms the head with the more diffuse IC 2177 as the wings and body. Impressively, the Seagull’s wingspan would correspond to about 250 light-years at an estimated distance of 3,800 light-years. At the lower right, the Duck appears much more compact and would span only about 50 light-years given its 15,000 light-year distance estimate. Blown by energetic winds from an extremely massive, hot star near its center, the Duck nebula is cataloged as NGC 2359. Of course, the Duck’s thick body and winged appendages also lend it a more dramatic popular moniker — Thor’s Helmet.
