This totally stunning composite picture depicts the Small Magellanic Cloud, one of the Milky Way's closest galactic neighbors. Astronomers recently announced that they'd managed to detect X-rays coming from the young stars, of similar size to Earth, in the SMC's "Wing."

You're looking at one of the most far-flung star explosions ever recorded. Dubbed Supernova UDS10Wil (aka "SN Wilson," after Woodrow Wilson), it detonated more than 10 billion years ago, but only recently has its light found its way to NASA's Hubble Space Telescope.

NASA has just released a photo captured by its Hubble Space Telescope that reveals a deep cosmic entity that looks suspiciously like a Space Invader. Not an alien race bent on human destruction, but rather a cluster of galaxies located billions of light years from Earth (dubbed "Abel 68"), observations of which bear a…

2012 was a remarkable year for jaw-dropping space imagery. Here, in no particular order, are our 22 favorite photos, videos, composites, timelapses and animations of the cosmos for the year.

Yesterday, NASA's Cassini imaging team brought us a rare view of a backlit Saturn to commemorate the holidays. Today, the Agency's Hubble Space Telescope celebrates the season with a gorgeous "cosmic holiday ornament."

Astronomers working with the Hubble Space Telescope have just released the most detailed view of the early Universe ever captured. It's called the eXtreme Deep Field, or XDF for short. The image combines over ten years' worth of photographs by Hubble. It required 2-million seconds of exposure time to produce, and…

Many people associate Hubble Space Telescope with beautiful images of the cosmos — but the truth is that the majority of Hubble's observations, while scientifically valuable, are pretty boring from a purely visual standpoint.

In 2018, the James Webb Space Telescope will become one of the greatest tools in humanity's quest to understand the cosmos. Now, after eight years, the technology comprising the heart and soul of the telescope — an ultra-sophisticated beryllium mirror system — is complete.

This galaxy is so large, so fully-formed, astronomers say it shouldn't exist at all. It's called a "grand-design" spiral galaxy, and unlike most galaxies of its kind, this one is old. Like, really, really old. According to a new study conducted by researchers using NASA's Hubble Telescope, it dates back roughly…
