How to Spot Comet ISON in the Early Morning Sky

OK, you’ve waited patiently for "Comet of the Century" ISON to brighten and reappear in the dawn sky. Now it has. Now you’re chomping at the bit for a look at it in your telescope. Before you set the alarm and venture into the night, let’s prepare for what to expect. The better you know your target, the easier it will be … » 9/04/13 11:09am 9/04/13 11:09am

Hubble Snaps Breathtaking New Picture of ISON, “Comet of the Century"

When Comet ISON's trajectory brings it scorchingly close to the Sun later this year, astronomers believe it could emerge from its close encounter as one of the brightest comets ever seen from Earth. Now, Hubble has captured a stunning image of the approaching ice-ball in flight, against a backdrop bursting with nearby… » 7/17/13 8:20am 7/17/13 8:20am

Astronomers have discovered a blue planet beyond our solar system

In a major breakthrough, researchers using the Hubble Space Telescope have seen the true color of a planet outside our solar system. HD 189733b, as the gas giant is called, is blue. A deep, vibrant, cobalt blue. And just wait til you hear why it's that color. » 7/11/13 11:26am 7/11/13 11:26am

Behold, the most distant supernova explosion ever photographed

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. » 4/04/13 1:46pm 4/04/13 1:46pm

Hubble telescope has just spotted a Space Invader

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… » 3/05/13 8:20am 3/05/13 8:20am

Feast your eyes on a jaw-dropping "Cosmic Holiday Ornament," courtesy of …

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." » 12/19/12 1:40pm 12/19/12 1:40pm

This spectacular image is the deepest view of the Universe ever…

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… » 9/26/12 8:00am 9/26/12 8:00am

Hubble has spotted an ancient galaxy that shouldn't exist

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… » 7/19/12 8:00am 7/19/12 8:00am

The most detailed picture yet of a star nursery birthing new suns

On April 24, 1990, the Hubble Space Telescope was lifted into low Earth orbit and promptly turned its attention to the depths of space. Today, over 10,000 publications and almost 22 years later, Hubble continues to change the way we see and understand our Universe with images that are truly awesome in every sense of… » 4/17/12 12:28pm 4/17/12 12:28pm

Astronomers discover a brand-new class of exoplanet — the boiling…

NASA's Kepler mission has been spoiling us with planetary discoveries left and right as of late. Now, researchers using NASA's Hubble Space Telescope have discovered an entirely new class of planet — they call it a "waterworld," and it might be covered in broiling-hot ice. » 2/21/12 11:21am 2/21/12 11:21am
