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

Impossibly, the Veil Nebula Appears to Flutter In Space

Only a small portion of the Veil Nebula — located in the constellation Cygnus — is only partly visible to the Hubble Telescope. But what can be photographed is fairly impressive. » 3/11/15 12:30am 3/11/15 12:30am

We Got to See This Supernova Explode Four Times Simultaneously

It's not every day we get to see a supernova, and a single exploding star split into four images is an absolute first. Here's how it happened. » 3/08/15 9:00am 3/08/15 9:00am

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

Start Your Weekend With The Hubble Space Telescope's Planetarium Clips

You may not own your own private planetarium — or if you do, can we come over to your house? But you can still experience a journey through the wonders of space, thanks to four new "fulldome" planetarium clips, released by the Hubble Space Telescope. They're available in 4K and 8K resolution. » 2/27/15 10:08pm 2/27/15 10:08pm

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

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

How did this black-and-white shot of a far-off star cluster transform into the full-color star explosion photo that NASA released? A series of Hubble shots goes through the process of getting their colors back in to show you how the pictures of stars, planets, and galaxies that we can't take our eyes off of are made. » 1/06/15 8:30am 1/06/15 8:30am

This New, High-Def View of the Eagle Nebula Is Awe-Inspiring

To celebrate 25 years of space-based telescope images, the Hubble telescope has taken a new, high-def version of its famous 1995 photograph of the Eagle Nebula's "Pillars of Creation." And of course, it's glorious. » 1/05/15 5:00pm 1/05/15 5:00pm

Two Different Satellites Take Two Different Pictures of the Same Galaxy

What a difference a wavelength makes: On the left is the M82 Galaxy as seen in the visible light spectrum, captured by the Hubble Space Telescope — and the image we most associate with that galaxy. On the right is an x-ray image of the same galaxy, taken by NASA's Chandra X-ray Observatory. » 12/19/14 12:00am 12/19/14 12:00am

A Brief Moment in the Death of a Star Produces Stunning Results

The Egg Nebula is 3,000 light years from Earth and is a "preplanetary nebula." This look is produced when a dying star's hot remains flare up and illuminate the surrounding cloud of gas and dust. » 12/08/14 11:00pm 12/08/14 11:00pm

This Galaxy Was Utterly Transformed by an Ancient Collision

This is the mysterious M64 galaxy, also called the "Black Eye" galaxy for the dark ring of dust around its bright core. In the 1990s, astronomers discovered that M64 probably collided with another galaxy, leaving a telltale sign of the smashup behind. » 12/03/14 5:38pm 12/03/14 5:38pm

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

Next Generation Telescopes Take Us Closer to Finding Alien Life

Every day we find more exoplanets. With bigger and better telescopes on the horizon, we'll have far more observations of these planets than ever before — and NASA scientists are optimistic we'll discover alien life within decades. » 7/16/14 5:45pm 7/16/14 5:45pm

Humans Have Been Going to the Moon for Almost Half a Century

Forty-five years ago today, Apollo 11 launched from Kennedy Space Center on humanity's first crewed mission to the surface of the moon. This view of Earth was captured from Apollo soon after translunar injection, just as the spacecraft was breaking away from our planet's orbit. » 7/16/14 10:20am 7/16/14 10:20am

The Hubble Just Spotted This Odd "Star Bridge" Connecting Two Galaxies

Using the Hubble telescope (along with the natural "zoom lens" of gravitational lensing) researchers over at NASA spotted this odd star structure, which they're describing as similar to both a spiral bridge and a corkscrew-shaped string of pearls. Close-ups after the jump. » 7/11/14 9:30am 7/11/14 9:30am

This Is The Most Complete Look At The Colors Of The Universe Ever Taken

The Hubble has given us some pretty stunningly colorful images in the past, but this picture — which takes the full range of colors that the Hubble is capable of shooting, from ultraviolet all the way up to almost infrared, and combines them all into one image — is the best yet. » 6/04/14 9:25am 6/04/14 9:25am

An Infant Star Pierces Through Its Birth Cloud

Happy Birthday, Hubble!

Today is the Hubble Space Telescope's birthday — it's been exactly 24 years since it was launched into orbit. The optical telescope captures drop-dead gorgeous images of space, and is a constant source of both new science and new computer wallpapers. » 4/24/14 12:00pm 4/24/14 12:00pm

This Cross-Section of the Universe Magnifies the Night Sky by a Billion

This cross-section of the universe, snapped by the Hubble, takes us about halfway to the universe's observable end — showing us things that you could only see with your eyes if your eyesight's power was magnified by a billion. » 4/17/14 2:12pm 4/17/14 2:12pm
