A beautiful time-lapse video of the night sky over Cape Hatteras, North Carolina, from Daniel Dragon Films. The Outer Banks is a wonderful place that I’ve visited for vacation dozens of times. Learn more about the stars you see here at Bad Astronomy Blog. Link
Researchers have discovered that only four percent of galaxies have similar qualities as our own Milky Way. I guess every galaxy really is a snowflake.
The research team compared the Milky Way to similar galaxies in terms of luminosity–a measure of how much light is emitted–and distance to other bright galaxies. They found galaxies that have two satellites that are as bright and close by as the Milky Way’s two closest satellites, the Large and Small Magellanic Clouds, are rare.
Filmmaker Terje Sorgjerd (previously at Neatorama) set up cameras on El Teide, the highest mountain in Spain, from April 4th to 11th, 2011. The object was to take a time-lapse video of the Milky Way. However, a sand storm blew in from the Sahara desert. Sorgjerd assumed his project had been ruined, but was pleased with the resulting video. -via the Presurfer

Where do stars go to have fun? Why, they go downtown in the Milky Way, of course. Take a look at this beautiful image taken by NASA’s Spitzer Space Telescope:
In this Spitzer image, the myriad of stars crowding the center of our galaxy creates the blue haze that brightens towards the center of the image. The green features are from carbon-rich dust molecules, called polycyclic aromatic hydrocarbons, which are illuminated by the surrounding starlight as they swirl around the galaxy’s core. The yellow-red patches are the thermal glow from warm dust. The polycyclic aromatic hydrocarbons and dust are associated with bustling hubs of young stars. These materials, mixed with gas, are required for making new stars.
The brightest white feature at the center of the image is the central star cluster in our galaxy. At a distance of 26,000 light years away from Earth, it is so distant that, to Spitzer’s view, most of the light from the thousands of individual stars is blurred into a single glowing blotch. Astronomers have determined that these stars are orbiting a massive black hole that lies at the very center of the galaxy.
The region pictured here is immense, with a horizontal span of 2,400 light-years (5.3 degrees) and a vertical span of 1,360 light-years (3 degrees). Though most of the objects seen in this image are located near the galactic center, the features above and below the galactic plane tend to lie closer to Earth.

Is life on Earth special? Not according to Carnegie Institution’s astronomer Alan Boss. The author of the new book The Crowded Universe: The Search for Living Planets predicted that there may be 100 billion Earth-like planets in the Milky Way:
[Boss] made the prediction based on the number of "super-Earths" — planets several times the mass of the Earth, but smaller than gas giants like Jupiter — discovered so far circling stars outside the solar system.
Boss said that if any of the billions of Earth-like worlds he believes exist in the Milky Way have liquid water, they are likely to be home to some type of life.
"Now that’s not saying that they’re all going to be crawling with intelligent human beings or even dinosaurs," he said.
"But I would suspect that the great majority of them at least will have some sort of primitive life, like bacteria or some of the multicellular creatures that populated our Earth for the first 3 billion years of its existence."
