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.

Hubble Sees Cosmic Quintuple

Clustered at the center of this image are six brilliant spots of light, four of them creating a circle around a central pair. Appearances can be deceiving, however, as this formation is not composed of six individual galaxies, but is actually two separate galaxies and one distant quasar imaged four times.

NASA’s James Webb Space Telescope Has Completed Testing

After successful completion of its final tests, NASA’s James Webb Space Telescope is being prepped for shipment to its launch site.

Hubble Views a Galaxy in a ‘Furnace’

This jewel-bright image from the NASA/ESA Hubble Space Telescope shows NGC 1385, a spiral galaxy 68 million light-years from Earth, which lies in the constellation Fornax.

Comet Atlas May Have Been a Blast From the Past

It's suspected that about 5,000 years ago a comet swept within 23 million miles of the Sun, closer than the innermost planet Mercury. The comet might have been a spectacular sight to civilizations across Eurasia and North Africa at the end of the Stone Age.

Mapping the Universe's Earliest Structures with COSMOS-Webb

With more than 200 hours of observing time, COSMOS-Webb will survey a large patch of the sky—0.6 square degrees—with the Near-Infrared Camera (NIRCam). That's the size of three full moons. It will simultaneously map a smaller area with the Mid-Infrared Instrument (MIRI).

Hubble Peers into a Dusty Stellar Nursery

This image from the NASA/ESA Hubble Space Telescope features AFGL 5180, a beautiful stellar nursery located in the constellation of Gemini (the Twins).

NASA's TESS Tunes into an All-sky ‘Symphony’ of Red Giant Stars

Using observations from NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have identified an unprecedented collection of pulsating red giant stars all across the sky.

Hubble Spots Squabbling Galactic Siblings

A dramatic triplet of galaxies takes center stage in this image from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational tug-of-war between interacting galaxies.

Fermi Spots a Supernova's "Fizzled" Gamma-ray Burst

On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected the weakest gamma-ray burst caused by the death of a massive star ever seen.

Hubble Finds First Evidence of Water Vapor at Jupiter's Moon Ganymede

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.

Hubble Views a Faraway Galaxy Through a Cosmic Lens

The center of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant galaxies.
