NASA reports that astronomers have detected X-rays from Uranus for the first time, using its Chandra X-ray Observatory.

Astronomers observed a black hole sucking in a faraway star, shredding it into thin strands of stellar material.

5 of the most unusual, amazing and interesting stars we've discovered in our universe. Red giants, supernovas, hybrid stars, orbiting binaries, large stars, old stars, small stars, we've discovered thousands of stars within our milky way...

Astronomers have seen light from BEHIND a black hole for the first time. I explained the discovery and results to my editor, Levi. Congrats to D. Wilkins and the astronomy team!

Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as...

Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known.



The pulsar...

This video explores five fun facts about Pluto.

Two stimulating films aimed at introducing students to the wonders of the universe, its size and its origin.



How Big is the Universe?: it is impossible for the human mind to grasp just how big the universe is, but astronomer...

Scientists using data from NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station have discovered X-ray surges accompanying radio bursts from the pulsar in the...

On April 15, a brief burst of high-energy light swept through the solar system, triggering instruments on many NASA missions. Now, multiple international science teams conclude that the blast came from a...

Some 3.9 billion years ago in the heart of a distant galaxy, the tidal pull of a monster black hole shredded a star that wandered too close. X-rays produced in this event first reached Earth on March 28, 2011, when they were...

Astronomers Help Focus Research in the Search for Another Earth: NASA in Silicon Valley Podcast

A feature story from NASA’s Ames Research Center in Silicon Valley originally posted on September 14, 2016.

Since the early 1990's, astronomers have known that extrasolar planets, or "exoplanets," orbit stars light-years beyond our own solar system. Although most exoplanets are too distant to be directly imaged, detailed studies have been...

A team from NASA's Goddard Space Flight Center in Greenbelt, Maryland, is developing a new, third-generation facility science instrument for the Stratospheric Observatory for Infrared Astronomy, SOFIA.

On October 19, Comet Siding Spring will pass within 88,000 miles of Mars – just one third of the distance from the Earth to the Moon! Traveling at 33 miles per second and weighing...

Eta Carinae is a binary system containing the most luminous and massive star within 10,000 light-years. A long-term study led by astronomers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, combined data from NASA...

NASA's Swift satellite rode to orbit aboard a Delta II rocket on November 20, 2004, and it's still going strong. Swift's unique instrumentation allows it to quickly locate an interesting high-energy outburst, automatically determine...

On April 28, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst (FRB) ever seen from within our Milky...

Astronomers have used many different methods to discover planets beyond the solar system, but the most successful by far is transit photometry, which measures changes in a star's brightness caused by a mini-eclipse. When a planet...

NASA’s Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening...

Shortly after NASA Administrator Michael Griffin announced that NASA would add a servicing mission to the Hubble Space Telescope, Hubbles most prominent camera and most used instrument, died.



The incredible engineering...

The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any previously seen from the object. The outburst was first detected by NASA's Fermi Gamma-ray Space Telescope on April 12...
