NASA Selects Gamma-ray Telescope to Chart Milky Way Evolution

NASA has selected a new space telescope proposal that will study the recent history of star birth, star death, and the formation chemical elements in the Milky Way.

Hubble Uncovers a Burst of Star Formation

NGC 4666, a majestic spiral galaxy, takes center stage in this image from the NASA/ESA Hubble Space Telescope.

Hubble Finds Evidence of Persistent Water Vapor in One Hemisphere of Europa

NASA’s Hubble Space Telescope observations of Jupiter’s icy moon Europa have revealed the presence of persistent water vapor – but, mysteriously, only in one hemisphere.

NASA’s Webb Space Telescope Arrives in French Guiana After Sea Voyage

NASA’s James Webb Space Telescope successfully arrived in French Guiana Tuesday, after a 16-day journey at sea.

Hubble Detects a Dangerous Dance

This NASA/ESA Hubble Space Telescope image features two interacting galaxies that are so intertwined, they have a collective name – Arp 91. Their delicate galactic dance takes place more than 100 million light-years from Earth.

NASA looks to AI, Lensing to Find Masses of Free-Floating Planets

Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy, not bound to any star. Many astronomers believe that these planets are more common than we know, but that our planet-finding techniques haven’t been up to finding them.

’Double’ Galaxy Mystifies Hubble Astronomers

Astronomers have seen some pretty weird things scattered across our vast universe, from exploding stars to colliding galaxies. So, you'd think that when they see a strange celestial object, they would be able to identify it.

Hubble Views a Galaxy with More than Meets the Eye

In this image, NCG 5728 appears to be an elegant, luminous, barred spiral galaxy. What this image doesn’t show, is that NGC 5728 is also a monumentally energetic type of galaxy, known as a Seyfert galaxy.

NASA Confirms Roman Mission's Flight Design in Milestone Review

NASA’s Nancy Grace Roman Space Telescope has successfully passed its critical design review, signaling that all design work is now complete.

NASA Goddard Visitor Center Offering Free Virtual Field Trips During 2021-2022 School Year

The visitor center at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is offering virtual field trips for groups looking for STEM engagement this school year. The field trips, which are free for the public, feature a live presentation and question-and-answer session led by trained staff.

Hubble Shows Winds in Jupiter's Great Red Spot Are Speeding Up

Like the speed of an advancing race car driver, the winds in the outermost "lane" of Jupiter's Great Red Spot are accelerating – a discovery only made possible by NASA's Hubble Space Telescope, which has monitored the planet for more than a decade.

Hubble Captures a Cluster in the Heart of the Milky Way

This sparkling starfield, captured by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys, contains the globular cluster ESO 520-21 (also known as Palomar 6).

Hubble Snapshot of "Molten Ring" Galaxy Prompts New Research

In this particular snapshot, a science discovery followed the release of a Hubble observation of a striking example of a deep-space optical phenomenon dubbed an "Einstein ring."

NASA’s Webb to Explore Forming Planetary Systems

Researchers will observe more than a dozen protoplanetary systems to gather data about their inner disks – where Earth-like planets may be forming.

Hubble Finds Early, Massive Galaxies Running on Empty

When NASA's Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array in northern Chile gazed toward cosmic objects in this period, they found something odd: six early, massive, "dead" galaxies that had run out of the cold hydrogen gas needed to make stars.

A New Understanding of Galaxy Evolution with NASA’s Roman Space Telescope

Roman will combine the powers of imaging and spectroscopy to gain fresh insights into how the universe works.

Hubble Takes a Closer Look at its 31st Anniversary Image

This comparison of two images shows puffing dust bubbles and an erupting gas shell – the final acts of a monster star’s life.

Rerun of Supernova Blast Expected to Appear in 2037

Astronomers have added a solid prediction of an event happening deep in intergalactic space: an image of an exploding star, dubbed Supernova Requiem, which will appear around the year 2037. Although this rebroadcast will not be visible to the naked eye, some future telescopes should be able to spot it.

Hubble Captures a Sparkling Cluster

This star-studded image from the NASA/ESA Hubble Space Telescope depicts NGC 6717, which lies more than 20,000 light-years from Earth in the constellation Sagittarius.

Small Satellite, Big Questions: CuPID CubeSat Will Get New Perspective on Sun-Earth Boundary

Launching with Landsat 9, a joint mission of NASA and the U.S. Geological Survey, are four CubeSats – compact, cube-shaped satellites used for space research projects. One of the CubeSats launching with Landsat 9 is the Cusp Plasma Imaging Detector, or CuPID.

NASA Readies James Webb Space Telescope for December Launch

NASA plans to launch the James Webb Space Telescope into orbit Dec. 18, 2021, to serve as the premier deep space observatory for the next decade.

Episode 2: We Asked a NASA Scientist: Is Mars Habitable?

Is Mars habitable? Could ancient life once have existed on the Red Planet? Is there potential for life today deep beneath the Martian crust?

Hubble Discovers Hydrogen-Burning White Dwarfs Enjoying Slow Aging

New evidence from Hubble suggests that white dwarf stars could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters, which contain the oldest known stars in the universe.

Hubble Snaps Speedy Star Jets

This striking image features a relatively rare phenomenon, a Herbig-Haro object. Newly formed stars sometimes expel narrow jets of fast-moving ionized gas. The jets then collide with the clouds of gas and dust surrounding newly formed stars at speeds of hundreds of miles per second. It is these energetic collisions that create Herbig-Haro objects.
