Have you ever seen images of colorful, wispy clouds of gas in space? Those are called nebulae! What happens inside a nebula? In some of them, new stars are born. How does that work? How can we see all this gas? Are there different types...

On June 11, NASA's Fermi Gamma-ray Space Telescope celebrates a decade of using gamma rays, the highest-energy form of light in the cosmos, to study black holes, neutron stars, and other extreme cosmic objects and...

Astronomers have discovered a new type of “spider star” — violent pulsars that shred material from companion stars<br/>

Black holes are often described as the monsters of the universe—tearing apart stars, consuming anything that comes too close, and holding light captive. Detailed evidence from NASA's Hubble Space Telescope, however,...

Astronomers at NASA and the ESA have discovered a star in the constellation Sagittarius that is the youngest known magnetar ever recorded.

This image, taken with the Hubble Space Telescope, shows a distant galaxy located in the constellation Fornax. It is the largest and one of the most complete Einstein rings ever discovered.



This object’s...

NASA is celebrating the Hubble Space Telescope’s 32nd birthday with a stunning look at five galaxies, a close-knit collection called the Hickson Compact Group 40.

This amazing assembly includes a giant elliptical...

Astronomers have used new and archival datasets from NASA’s Hubble Space Telescope to uncover evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede.

Fast radio bursts, or FRBs, are extraordinary events that generate as much energy in a thousandth of a second as the Sun does in an entire year!



Astronomers using NASA’s Hubble Space Telescope have...

Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68 percent of the total energy content of the cosmos, but so far we don't know much more about it. Exploring the...

Recently astronomers used the Suzaku orbiting X-ray observatory, operated jointly by NASA and the Japanese space agency, to discover the largest known reservoir of rare metals in the universe. Suzaku detected the elements chromium and...

For the past 30 years the Hubble Space Telescope has continued its important mission of uncovering the mysteries of the universe. One of those mysteries that Hubble has helped us understand...

Our universe is more than a serene landscape of stars--it is teeming with activity from some extremely violent events. In a presentation at the IMAX theatre at the Smithsonian National Air and Space Museum in Washington, D.C. on...

The Second Servicing Mission, launched Feb. 11, 1997, greatly improved Hubble's productivity. The installation of new instruments extended Hubble's wavelength range into the near infrared for imaging and...

For the past 31 years, the Hubble Space Telescope has continued its important mission of uncovering the mysteries of the universe. One of those mysteries that Hubble has helped us begin to understand is...

A spectacular head-on collision between two galaxies fueled an unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope.



The interacting galaxy duo is...

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity.



The planet,...

A team of astronomers at The Ohio State University watched a star disappear and possibly become a black hole. Instead of becoming a black hole through the expected process of a supernova, the black hole candidate formed...

Afterschool Universe is an out-of-school-time astronomy program for middle school students that explores basic astronomy concepts through engaging hands-on activities and then takes participants on a journey through the Universe...

In celebration of the 31st anniversary of the launching of NASA’s Hubble Space Telescope on April 24, 1990, astronomers aimed the renowned observatory at a brilliant “celebrity star,” one of the brightest...

Dr. Amy Simon has always been fascinated with space. From a young age she dreamed of lifting off in the space shuttle, just like her hero, astronaut Sally Ride. Over the years her interest in space remained, and...

NASA officially is beginning work on an astrophysics mission designed to help unlock the secrets of the universe -- the Wide Field Infrared Survey Telescope (WFIRST).



With a view 100 times bigger than that of...

Major improvements to methods used to process observations from NASA's Fermi Gamma-ray Space Telescope have yielded an expanded, higher-quality set of data that allows astronomers to produce the most detailed census of the sky yet...

Shortly after the Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images....
