NASA’s Webb Redefines Dividing Line Between Planets, Stars
2026.04.14
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way. Astronomers used NASA’s James Webb Space Telescope to examine 29 Cygni b, an object […]
Hubble Spies an Active Spiral
2026.04.13
A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA Hubble Space Telescope image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, […]

2026.03.26
Media are invited Tuesday, April 21, to NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for a look at the agency’s Nancy Grace Roman Space Telescope, which recently completed construction and is wrapping up prelaunch testing. This will be one of the last opportunities to view the fully integrated flagship telescope before it ships to […]
NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet
2026.03.26
Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence […]
NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date
2026.03.25
NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere. Both sense sunlight reflected from Saturn’s banded […]
NASA-JAXA’s XRISM Telescope Clocks Hot Wind of Galaxy M82
2026.03.25
For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82, a nearby galaxy undergoing an extraordinary burst of star formation.
NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion
2026.03.23
A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation is published […]
NASA’s Roman Observatory Passes Final Major Prelaunch Tests
2026.03.19
NASA’s Nancy Grace Roman Space Telescope team recently blasted the observatory with extreme sound, shook it, and listened to its electronic hum. Roman passed all three assessments, which aimed to confirm that the observatory will withstand launch conditions and function as expected in space. The achievement keeps the mission on track for launch as early […]
NASA’s Hubble Unexpectedly Catches Comet Breaking Up
2026.03.18
In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]
Artifacts From NASA’s Webb, Parker Solar Probe on View at Smithsonian
2026.03.13
A testing replica of the “backbone” of NASA’s James Webb Space Telescope and a full-scale model of the agency’s Parker Solar Probe are now on permanent display at the Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Virginia.
Two Observatories, One Cosmic Eye: Hubble and Euclid View Cat’s Eye Nebula
2026.03.03
This new NASA/ESA Hubble Space Telescope image features one of the most visually intricate remnants of a dying star: the Cat’s Eye Nebula, also known as NGC 6543. This extraordinary planetary nebula lies in the constellation Draco and has captivated astronomers for decades with its elaborate and multilayered structure. Observations with ESA’s Gaia mission place the nebula at 4,400 light-years away. […]
NASA’s Webb Examines Cranium Nebula
2026.02.25
Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the […]
NASA’s Webb Telescope Locates Former Star That Exploded as Supernova
2026.02.23
Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, 2025, where it was detected by the All-Sky Automated Survey for Supernovae. Astronomers immediately turned their resources to this new supernova, designated 2025pht, […]
NASA’s Hubble Identifies One of Darkest Known Galaxies
2026.02.18
In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible — low-surface-brightness galaxies dominated by dark matter and containing only a sparse scattering of faint stars. One such elusive object, dubbed CDG-2, may be among the most heavily dark matter-dominated […]
NASA’s Hubble Captures Light Show Around Rapidly Dying Star
2026.02.10
This stunning image from NASA’s Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation Cygnus, the Egg Nebula features a central star obscured by a dense cloud of dust — like a “yolk” nestled within a […]
Core Survey by NASA’s Roman Mission Will Unveil Universe’s Dark Side
2026.02.10
The broadest planned survey by NASA’s upcoming Nancy Grace Roman Space Telescope will reveal hundreds of millions of galaxies scattered across the cosmos. After Roman launches as soon as this fall, scientists will use these sparkly beacons to study the universe’s shadowy underpinnings: dark matter and dark energy. “We set out to build the ultimate […]
Hubble Sees Galaxy with Dark Rings in New Light
2026.01.30
This NASA/ESA Hubble Space Telescope image features an uncommon galaxy with a striking appearance. NGC 7722 is a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A lenticular, meaning “lens-shaped,” galaxy is a type whose classification sits between more familiar spiral galaxies and elliptical galaxies. It is also less common than spirals and ellipticals — partly because […]
