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.

NASA Scientist Honored with Distinguished Federal Service Award

Dr. Stephanie Schollaert Uz of NASA's Goddard Space Flight Center in Greenbelt, Maryland, has been awarded the Arthur S. Flemming Award for Applied Science.

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.

Eruption at La Soufrière

Explosive activity has propelled ash and gas high into the air over the Caribbean islands of Saint Vincent and Barbados.

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.

NASA’s 2021 Virtual Earth Day Event – Online, April 21–24

NASA’s 2021 Virtual Earth Day Event – Online, April 21–24 You’re invited to NASA’s 2021 Virtual Earth Day Event, held April 21-24. Registration is FREE and open to the public!

Cyclone Seroja Slams Australia

The category three cyclone made a rare landfall in Western Australia, causing significant damage to coastal towns.

Hiding in Plain Sight

Springtime ocean conditions promote North Atlantic blooms, but you wouldn't know that from looking with human eyes.

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.

Pacaya Heats Up

Lava flows from the persistent Guatemalan volcano are approaching some nearby villages.

NASA's OSIRIS-REx Completes Final Tour of Asteroid Bennu

Early this morning, April 7, 2021, NASA's OSIRIS-REx mission completed its last flyover of near-Earth asteroid Bennu. OSIRIS-REx, with its pristine and precious asteroid sample cargo, will remain in the vicinity of Bennu until May 10, when it will fire its thrusters and begin its two-year cruise home.

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.

NASA's Lucy Stretches Its Wings in Successful Solar Panel Deployment Test

NASA???s Lucy spacecraft has successfully completed thermal vacuum testing of both solar panels, the final step in checking out these critical spacecraft components in preparation for launch this fall. Once the Lucy spacecraft???s solar panels attached and fully extended, they could cover a five-story building.

What a Glacial River Reveals About the Greenland Ice Sheet

With data from a 2016 expedition, scientists supported by NASA are shedding more light into the complex processes under the Greenland Ice Sheet that control how fast its glaciers slide toward the ocean and contribute to sea level rise.

NASA's Curiosity Team Names Martian Hill That Serves as Mission 'Gateway'

The team of scientists and engineers behind NASA's Curiosity rover named a hill along the rover's path on Mars in honor of a recently deceased mission scientist.

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.

Dry Ice: How Expanding Antarctic Sea Ice is Drying the Atmosphere Over the Southern Ocean

Evaporation plays an important role in the global water and energy cycles and therefore in climate change. AIRS data were used in a study to help quantify evaporation over the Southern Ocean, where the Antarctic sea ice coverage has a large annual cycle.

Drought Conditions Continue in Spring 2021

The western United States is currently experiencing moderate to severe drought, and it is expected to worsen in upcoming months.

NASA OSIRIS-REx's Final Asteroid Observation Run

On Apr. 7, the OSIRIS-REx spacecraft will get one last close encounter with Bennu as it performs a final flyover to capture images of the asteroid's surface.

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.

NASA Finds 2021 Arctic Winter Sea Ice Tied for 7th-Lowest on Record

Sea ice in the Arctic appears to have hit its annual maximum extent after growing through the fall and winter. This year's maximum extent peaked at 5.70 million square miles, making it the seventh-smallest on record and tied with 2007.
