Hubble Watches Cosmic Light Bend

Hubble captured this image of the galaxy cluster Abell 2813 demonstrating spectacularly the concept of gravitational lensing.

Gravity Assist: Black Hole Mysteries, with Jeremy Schnittman

What is a black hole? How do we study them when we can???t see them? Astrophysicist Jeremy Schnittman from NASA???s Goddard Space Flight Center joins NASA Chief Scientist Jim Green for a fascinating conversation about the latest black hole research.

New NASA Visualization Probes the Light-bending Dance of Binary Black Holes

A pair of orbiting black holes millions of times the Sun???s mass perform a hypnotic dance in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas ??? called an accretion disk ??? that surrounds each one.

How NASA's Roman Space Telescope Will Uncover Lonesome Black Holes

The Nancy Grace Roman Space Telescope's microlensing survey also provide the best opportunity yet to definitively detect solitary stellar-mass black holes for the first time.

Hubble Takes a Spiral Snapshot

The luminous heart of the galaxy M61 dominates this image, framed by its winding spiral arms threaded with dark tendrils of dust.

NASA's NICER Finds X-ray Boosts in the Crab Pulsar's Radio Bursts

Data from NASA???s NICER telescope on the International Space Station have revealed X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.

NASA's Webb Telescope Packs Its Sunshield for a Million Mile Trip

Engineers working on NASA???s James Webb Space Telescope have successfully folded and packed its sunshield for its upcoming million-mile (roughly 1.5 million kilometer) journey, which begins later this year.

Hubble Spots Double Quasars in Merging Galaxies

NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based telescopic photos, but not in Hubble???s crisp view.

Hubble Revisits the Veil Nebula

This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release.

NASA's Roman Mission Predicted to Find 100,000 Transiting Planets

Scientists predict that the data collected for Roman's microlensing survey will provide an additional bounty of roughly 100,000 transiting planets, worlds that periodically dim the light of their stars as they cross in front of them.

NASA's James Webb Space Telescope General Observer Scientific Programs Selected

Selected programs describe what Webb will study for much of its first year in space.

Hubble Spots a Galaxy with a Peculiar Arm

This image taken with the NASA/ESA Hubble Space Telescope features NGC 7678.

Pandora Mission Would Expand NASA's Capabilities in Probing Alien Worlds

In the quest for habitable planets beyond our own, NASA is studying a mission concept called Pandora, which could eventually help decode the atmospheric mysteries of distant worlds in our galaxy.

Hubble Captures Re-energized Planetary Nebula

Located around 5,000 light-years away in the constellation of Cygnus (the Swan), Abell 78 is an unusual type of planetary nebula.

Hubble Shows Torrential Outflows from Infant Stars May Not Stop Them from Growing

Scientists know that stars form from the collapse of huge hydrogen clouds that are squeezed under gravity to the point where nuclear fusion ignites. But only about 30 percent of the cloud's initial mass winds up as a newborn star.

Hubble Sees Changing Seasons on Saturn

NASA???s Hubble Space Telescope is giving astronomers a view of changes in Saturn???s vast and turbulent atmosphere as the planet???s northern hemisphere summer transitions to fall in this series of images taken in 2018, 2019, and 2020 (left to right).

Peering into a Galaxy's Dusty Core to Study an Active Supermassive Black Hole

Researchers using NASA's James Webb Space Telescope will map and model the core of nearby galaxy Centaurus A.

NASA's Hubble Space Telescope's Wide Field Camera 3 Restored

The Hubble Space Telescope returned to science operations on Thursday, March 11 at 8:00 p.m. EST.

Hubble Views a Galaxy with Faint Threads

Known as NGC 1947, this galaxy was discovered almost 200 years ago by James Dunlop, a Scottish-born astronomer who later studied the sky from Australia. NGC 1947 can only be seen from the southern hemisphere, in the constellation Dorado (the Dolphinfish).

Scientists Sketch Aged Star System Using Over a Century of Observations

Astronomers have painted their best picture yet of an RV Tauri variable, a rare type of stellar binary where two stars -one approaching the end of its life - orbit within a sprawling disk of dust. Their 130-year dataset spans the widest range of light yet collected for one of these systems, from radio to X-rays.

Distant Planet May Be On Its Second Atmosphere, NASA's Hubble Finds

Scientists using NASA's Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity.

NASA's Hubble Space Telescope Set to Resume Science Operations

NASA is working to return the Hubble Space Telescope to science operations after resolving a problem with a safeguard aboard.

Hubble Beholds a Big, Beautiful Blue Galaxy

NGC 2336 is the quintessential galaxy - big, beautiful, and blue - and it is captured here by the NASA/ESA Hubble Space Telescope.

Hubble Solves Mystery of Monster Star's Dimming

Last year, astronomers were puzzled when Betelguese, the bright red supergiant star in the constellation Orion, dramatically faded, but then recovered. The dimming lasted for weeks. Now, astronomers have turned their sights toward a monster star in the adjoining constellation Canis Major, the Great Dog.

New 'Eyewear' to Deepen the View of NASA's Roman Space Telescope

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 up exciting new opportunities for discoveries from the edge of our solar system to the farthest reaches of space.
