After Pluto, Where Will NASA's New Horizons Go?

Scientists are mulling over which of two icy bodies NASA's New Horizons spacecraft should visit following its Pluto encounter this summer — provided the U.S. space agency comes up with funding for an extended mission. » 3/22/15 9:30am 3/22/15 9:30am

The Monkey Roars! NASA just released this beautiful mosaic image of part of the Monkey Head Nebula, showing a cloud made up of ultraviolet light hitting cooler hydrogen gas. This image is partly visible light and partly infrared, which shows interstellar dust particles heated by radiation from the stars in the middle. » 3/19/15 11:45pm 3/19/15 11:45pm

There May Be More Water On Jupiter's Largest Moon Than On Earth

By studying the subtle shifts of aurorae on Ganymede, scientists working with the Hubble Space Telescope have concluded that Jupiter's largest moon hosts a massive subterranean ocean. Quite suddenly, the outer reaches of our solar system appear to be a very wet place, indeed. » 3/13/15 12:50pm 3/13/15 12:50pm

A Baby Star Pierces Through Its Blanket Of Interstellar Dust

Behold V1331Cyg, a young star located 1,800 light-years from Earth. This object, which is illuminating the dark cloud around it in spectacular fashion, is in the process of contracting as it becomes a main sequence star similar to the Sun. » 3/02/15 7:20am 3/02/15 7:20am

Gaze In Amazement At This Image Depicting Thousands Of Galaxies

The Coma Cluster of Galaxies is composed of thousands of galaxies (and billions of stars), just a fraction of which can be seen in this image. It was created in 2006 by the Hubble Space Telescope as part of an initiative to learn how galaxies in rich clusters form and evolve. » 3/01/15 5:00pm 3/01/15 5:00pm

Our Best View Of A Stellar Debris Disk Warped By A Massive Exoplanet

Astronomers working with the Hubble Space Telescope have released the most detailed picture ever taken of a circumstellar debris disk viewed edge-on. It's the only picture we have of a protoplanetary disk with an actual planet orbiting within it. » 2/20/15 9:20am 2/20/15 9:20am

Marvel At The Sparkling, Spiraling Majesty Of The M100 Galaxy

A Near-Collision Stretched This Galaxy Like A "Taffy Pull"

Why does this galaxy have such a long curvy tail coming off it? That river of sunlike stars, going into deep space, was pulled away from NGC 7714 due to the gravitational pull of a galaxy passing by. » 1/29/15 3:23pm 1/29/15 3:23pm

Our Best Glimpse Yet Of The Andromeda Galaxy

You're looking at the biggest and sharpest image ever taken of the Andromeda Galaxy. Though it only includes one third of the massive celestial object, the image contains a jaw-dropping 1.5 billion pixels. » 1/06/15 3:30pm 1/06/15 3:30pm

Teal Tendrils Of The Tarantula Nebula Are Simply Beautiful

Once again, it's time to bask in the stunning wonder of our universe. This is the Tarantula Nebula, and my most recent excuse to bask in endless, encompassing joy. » 10/31/14 5:03am 10/31/14 5:03am

What Caused This Creepy Hubble Telescope Image of Jupiter's Red Spot?

Hubble was monitoring changes in Jupiter's Great Red Spot, when it captured this uncanny image of a dark circle moving across the face of the storm. » 10/28/14 1:00pm 10/28/14 1:00pm

Comet Siding Spring and Mars In One Beautiful Image

Shockwaves Are Driving This Galaxy To Its Imminent Doom

This galaxy looks like our own Milky Way, except for a pair of spiral arms emerging out of the galactic plane. That one anomaly is enough to radically change the evolution of NGC 4258, as powerful jets are generating shockwaves driving gas right out of the galaxy and slowing star growth to a crawl. » 9/10/14 1:03am 9/10/14 1:03am

Help Make The LEGO Hubble Space Telescope A Reality

Next year, the Hubble Space Telescope, one of the most important scientific instruments in the history of space exploration, will celebrate its 25th year in space. We think a LEGO play set would make a lovely 25th anniversary homage, don't you? » 7/20/14 12:00pm 7/20/14 12:00pm

An Infant Star Pierces Through Its Birth Cloud

See that brilliant cloud beneath the prominent blue star? If you look carefully you can see a young star cloaked in the haze of the molecular cloud in which it formed. » 5/26/14 9:30am 5/26/14 9:30am

Comet Siding Spring Is Headed Towards Mars

Comet Siding Spring is headed towards Mars. Not to worry, though. With its projected trajectory having it miss Mars by 84,000 miles, the comet is unlikely to make much of an impact on the red planet — but its dust might. » 3/28/14 8:40am 3/28/14 8:40am

Haunting new Hubble image shows a galaxy being ripped to shreds

There's a spiral galaxy located 200 million light years from here that's not doing so well. See those intense blue streaks streaming away from it? Those are hot young stars that are being torn away from the galaxy by its surroundings as it moves through space. » 3/04/14 1:20pm 3/04/14 1:20pm

NASA captures unprecedented 360-degree views of Saturn's auroras

Like Earth, Saturn features active and radiant auroras at its poles. To date, our impressions of these fantastic features have been fleeting and sporadic at best. But now, using several pairs of telescopic eyes, NASA has caught its best glimpse yet of these massive, swirling auroras. » 2/12/14 1:20pm 2/12/14 1:20pm

An Eyepopping Collection of 100 Planetary Nebulas

Artist Judy Schmidt, aka Geckzilla, does her own processing of raw images from the Hubble Space Telescope and other sources. And inspired by posters of insect illustrations, she decided to create this image of 100 planetary nebulas, all in one place. Enjoy! » 12/25/13 5:00pm 12/25/13 5:00pm
