the view from our pale blue dot…breathtaking

Because of the time it takes for light in the distant universe to reach Earth, when we look at, for example, a star a billion light-years away, we’re actually seeing what a portion of the cosmos looked like a billion years ago.

So, by combining pictures of various reaches of a small patch of sky, Hubble’s new eXtreme Deep Field (XDF) image, released Tuesday, essentially flattens time. Primitive, 13-billion-year-old galaxies—born just 450 million years after the big bang—seem to float side-by-side with closer, more advanced galaxies.

As “the deepest image of the sky ever obtained,” the XDF picture “reveals the faintest and most distant galaxies ever seen,” Hubble astronomer Garth Illingworth, of the University of California, Santa Cruz, said in a statement.

And some of the prettiest. “It’s beautiful,” said Geza Gyuk, director of astronomy at Chicago’s Adler Planetarium. “The level of detail is amazing, and being able to look that far back in time is incredible. You can begin to really see the vast majority of the history of the universe in a single image.”

NASA's Lunar Reconnaissance Orbiter (LRO), which reached orbit around the moon last month, passed over the Sea of Tranquility on Sunday and spied the Apollo 11 lunar module, still resting on the surface.

The lander set down on the moon by Buzz Aldrin and Neil Armstrong in 1969 is at the center of this image, a small white dot [arrow] with a long shadow stretching to the right. Each pixel in the photograph, which comes from the LRO's Narrow Angle Camera, is 1.14 meters across, so the Apollo 11 craft is just a few pixels wide.
