Suzaku Finds Common Chemical Makeup at Largest Cosmic Scales

A new survey of hot, X-ray-emitting gas shows that the elements needed to make stars, planets and people were evenly distributed across millions of light-years early in cosmic history.

Explore@NASAGoddard 2015 Concludes

Gates opened to the public Sept. 26, 2015, at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the first time in four years in celebration of Hubble's 25th anniversary.

Open House Sneak Peek: Explore Goddard’s Latest Science

Since it last opened its gates to the public in 2011, NASA's Goddard Space Flight Center has seen rapid growth and discovery in its four science disciplines...

Astronomers Identify a New Mid-size Black Hole

Nearly all black holes come in one of two sizes: stellar mass black holes (up to a few dozen times the mass of our sun) or supermassive black holes (a million to several billion times the sun’s mass).

NASA Goddard Opens Doors to Public to Explore@NASA Goddard, Free Event

NASA's Goddard Space Flight Center in Greenbelt, Maryland, is opening its doors for the first time in four years to give the public a chance to explore what happens behind the gates of the campus.

Science Jamboree Attracts Interns, Scientists from Across Goddard

From cryogenically frozen marshmallows and pennies to 3D printed supernova, Tuesday’s Science Jamboree filled the atrium in Building 28 with science displays and demonstrations.

Searing Sun Seen in X-rays

X-rays light up the surface of our sun in a bouquet of colors in this new image containing data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR.

Potentially Revolutionary Mission Heading for 2016 Launch

A NASA mission that embodies the virtues of faster, less expensive access to space has sailed past all major development milestones and is on schedule for its October 2016 launch.

Suzaku Studies Supernova 'Crime Scene,' Shows a Single White Dwarf to Blame

Using archival data from the Japan-led Suzaku X-ray satellite, astronomers have determined the pre-explosion mass of a white dwarf star that blew up thousands of years ago.

NASA, ESA Telescopes Give Shape to Furious Black Hole Winds

NASA's NuSTAR & ESA’s XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions, a phenomenon that had been suspected, but difficult to prove.

NASA's Swift Mission Observes Mega Flares from a Mini Star

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star.

Evidence for Supernovas Near Earth

Once every 50 years, more or less, a massive star explodes somewhere in the Milky Way. At its peak, a supernova can outshine the entire Milky Way.

RXTE Satellite Decodes the Rhythm of an Unusual Black Hole

Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite.

NASA-funded X-ray Instrument Settles Interstellar Debate

New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky.

Iron 'Fingerprints' Point Astronomers to Supernova Suspects

An international team of astronomers using data from the Japan-led Suzaku X-ray observatory has developed a powerful technique for analyzing supernova remnants.

New Suspect Identified in Supernova Explosion

New results from NASA's Spitzer Space Telescope have revealed a rare example of Type Ia explosion, in which a dead star "fed" off an aging star like a cosmic zombie, triggering a blast.

WFIRST: Uncovering the Mysteries of the Universe

The Wide-Field Infrared Survey Telescope (WFIRST) is an upcoming space telescope designed to perform wide-field imaging and spectroscopy of the infrared sky.

RXTE Reveals the Cloudy Cores of Active Galaxies

Using data from the RXTE satellite, an international team has uncovered a dozen instances where X-ray signals from active galaxies dimmed as a result of a cloud of gas moving across our line of sight.

NASA Sees 'Watershed' Cosmic Blast in Unique Detail

On April 27, a blast of light from a dying star in a distant galaxy became the focus of astronomers around the world.

Suzaku Study Points to Early Cosmic 'Seeding'

Most of the universe's heavy elements, including the iron central to life itself, formed early in cosmic history and spread throughout the universe, according to a new study.

Astronomers Uncover a 'Transformer' Pulsar

An international team of scientists using a fleet of orbiting X-ray telescopes, including NASA's Swift and Chandra X-ray Observatory, has discovered a millisecond pulsar with a dual identity.

Science Outreach Reaches In

Some 60 scientists, researchers, interns and outreach personnel manned stations for the annual Science Jamboree at NASA’s Goddard Space Flight Center in Greenbelt, Md., on July 16.

Black Hole Naps Amidst Stellar Chaos

NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now,NuSTAR results imply it went dormant.

NASA's Swift Produces Best Ultraviolet Maps of the Nearest Galaxies

Astronomers at NASA and Pennsylvania State have used the Swift satellite to create the most detailed ultraviolet light surveys ever of the Large and Small Magellanic Clouds.
