UGC 2885
NASA's Hubble Surveys Gigantic Galaxy
This majestic spiral galaxy might earn the nickname the "Godzilla Galaxy" because it may be the largest known in the local universe. The galaxy, UGC 2885, is 2.5 times wider than our Milky Way and contains 10 times as many stars. But it is a "gentle giant," say researchers, because it looks like...

Dying Young: Massive Dead Disk Galaxy Challenges the Picture of How Galaxies Evolve
By combining the power of a “natural lens” in space with the capability of NASA’s Hubble Space Telescope, astronomers made a surprising discovery—the first example of very compact yet massive disk-shaped and rotating galaxy that stopped making stars only a few billion years after the big bang....

Hubble-Spitzer Color Mosaic of the Galactic Center
This composite color infrared image of the center of our Milky Way galaxy reveals a new population of massive stars and new details in complex structures in the hot ionized gas swirling around the central 300 light-years. This sweeping panorama is the sharpest infrared picture ever made of...
NGC 1365
Portrait of the Great Barred Spiral
This image captures the elegant galaxy NGC 1365 in the Fornax Cluster of galaxies. Also known as The Great Barred Spiral Galaxy, NGC 1365 is a strikingly perfect example of a barred spiral galaxy. This image shows the galaxy’s prominent bar and its graceful spiral arms, with lanes of dust...

Galactic Center in Thermal IR
The center of our Milky Way Galaxy showing emission from hot gas that will either form stars or feed the supermassive black hole at the center of our galaxy. Technical Details: The image quality for this Brackett-alpha (hydrogen) line image is FWHM=0.35 arcsec. This image was obtained with the...
Messier 106
Galactic Pyrotechnics on Display
A galaxy about 23 million light-years away is the site of impressive, ongoing, fireworks. Rather than paper, powder, and fire, this galactic light show involves a giant black hole, shock waves, and vast reservoirs of gas.

NASA's Great Observatories Examine the Galaxy Center
In celebration of the International Year of Astronomy 2009, NASA's Great Observatories -- the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory -- have produced a matched trio of images of the central region of our Milky Way galaxy.

Spitzer View of the Center of the Milky Way
This dazzling infrared image from NASA's Spitzer Space Telescope shows hundreds of thousands of stars crowded into the swirling core of our spiral Milky Way galaxy.
Sgr A*
Earliest Phase of Star Formation Ever Observed in Highly Hostile Environment
An ALMA image of the center of the Milky Way galaxy showing the location of 11 young protostars within about 3 light-years of our galaxy's supermassive black hole. The lines indicate the direction of the bipolar lobes created by high-velocity jets from the protostars. The illustrated star in the...

High-Energy X-rays Fill Center of our Galaxy
This picture from NASA's Nuclear Spectroscopic Telescope Array, NuSTAR, shows very center of our Milky Way galaxy. Scientists were surprised to find more high-energy X-rays than predicted in the surrounding regions, seen here as the elliptical haze.

Scientists Discover Supernova May Control Activity in the Center of Our Galaxy
Supernova remnant Sagittarius A East. For the first time, Chandra has resolved the complex structures at the center of our Milky Way galaxy through X-ray observations. In addition to the supermassive black hole, Sgr A*, astronomers have found the remains of a supernova that exploded some 10,000...

WISE J224607.57-052635.0
Dusty 'Sunrise' at Core of the Brightest Known Galaxy
This artist's concept depicts the current record holder for the most luminous galaxy in the universe. The galaxy, named WISE J224607.57-052635.0, is erupting with light equal to more than 300 trillion suns. It was discovered by NASA's Wide-Field Infrared Survey Explorer, or WISE. The galaxy is...

A Spiral Galaxy is Visited by a Trojan War Hero
In the center of this new mosaic image captured by NASAs Wide-field Infrared Survey Explorer (WISE) is the galaxy Messier 74, with its spiral arms seen face-on. The bright reddish object moving across the lower right part of the image is the much closer asteroid 3540 Protesilaos, seen at...
Circinus Galaxy
A Super Special Galaxy
At a distance of 14 million light-years, the Circinus Galaxy is one of the nearest galaxies, yet is largely unexplored because the Milky Way veils it. There are so many stars and so much dust from our own galaxy obscuring the Circinus galaxy. In fact, this galaxy has two extended spiral arms,...
