NASA Looks Back at 50 Years of Gamma-Ray Burst Science

Fifty years ago, on June 1, 1973, astronomers around the world were introduced to a powerful and perplexing new phenomenon called gamma-ray bursts, now seen somewhere in the sky about once a day on average. Astronomers think the bursts arise from catastrophic occurrences involving stars in distant galaxies, events thought to produce new black holes

NASA Supercomputer Enables Seasonal Forecasts for High Mountain Asia

Using forecasts run on a our Center for Climate Simulation (NCCS) supercomputer, scientists from US agencies and universities; and the Korea National University of Transportation assessed the ability of the GEOS-S2S-2 forecasting system to predict atmospheric and land surface conditions throughout the High Mountain Asia region.

Mawar Churns in the Pacific

After strengthening rapidly and grazing the Philippines and Taiwan, the storm headed north toward the Sakishima Islands.

Webb Maps Surprisingly Large Plume Jetting From Saturn’s Moon Enceladus

A water vapor plume from Saturn’s moon Enceladus spanning more than 6,000 miles – nearly the distance from Los Angeles, California to Buenos Aires, Argentina – has been detected by researchers using NASA’s James Webb Space Telescope.

Astronomers Discover Planets in NASA Kepler's Final Days of Observations

A team of astrophysicists and citizen scientists have identified what may be some of the last planets NASA’s retired Kepler space telescope observed during its nearly decade-long mission.

Coastal Phytoplankton on the Rise

Blooms of the plant-like organisms near coastal areas have become more frequent in the 21st century.

Hubble Captures a Drifting Galaxy

The jellyfish galaxy JW39 hangs serenely in this image from the NASA/ESA Hubble Space Telescope.

NASA, Rocket Lab Complete Launch of TROPICS CubeSat Constellation

The final pair of NASA’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) are in orbit after successfully launching at 11:46 p.m. EDT, May 25, (3:46 p.m. NZST Friday, May 26th), completing the constellation.

Typhoon Mawar

The category 4 storm was one of the strongest in decades to lash the U.S. territory of Guam.

NASA's Chandra, Webb Combine for Arresting Views

Four composite images deliver dazzling views from NASA's Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. Each image combines Chandra's X-rays — a form of high-energy light — with infrared data from previously released Webb images, both of which are invisible to the unaided eye.

NASA's Hubble Hunts for Intermediate-Sized Black Hole Close to Home

Astronomers using Hubble have come up with what they say is some of their best evidence yet for the presence of a rare class of "intermediate-sized" black hole that may be lurking in the heart of the closest globular star cluster to Earth.

Spain Browned by Drought

Unseasonable heat and meager rainfall parched the world’s largest olive oil producing region in spring 2023.

Sander Goossens: Exploring the Solar System From Here On Earth

Goddard planetary scientist Sander Goossens uses "remote learning" - that is, satellite data, like radio tracking data, image data, or altimetry - to study planetary bodies in our solar system.

NASA’s LRO Views Impact Site of HAKUTO-R Mission 1 Moon Lander

On April 26, 2023, NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft acquired 10 images around HAKUTO-R Mission 1 lunar lander's landing site with its Narrow Angle Cameras.

NASA Mission to Study Ice Clouds, Help Observe Our Dynamic Atmosphere

NASA has selected a new mission to help humanity better understand Earth’s dynamic atmosphere – specifically, ice clouds that form at high altitudes throughout tropical and sub-tropical regions. The PolSIR instrument – short for Polarized Submillimeter Ice-cloud Radiometer – will study such ice clouds to determine how and why they change throughout

Retreat at Petermann Glacier

Decades of retreat are visible from above, but harder-to-see changes below the waterline could also affect this iconic glacier’s future.

Hubble Peers into a Glistening Star Cluster

The densely packed globular cluster NGC 6325 glistens in this image from the NASA/ESA Hubble Space Telescope.

NASA Goddard Hosts Third Cross-Agency Workshop on Artificial Intelligence and Data Science

To better prepare NASA to leap into an exciting future leveraging artificial intelligence and machine learning, NASA’s Science Mission Directorate and Goddard's Engineering and Technology Directorate hosted the Third SMD and ETD Workshop on A.I. and Data Science: Leaping Toward Our Future Goals, on March 21–23 at NASA's Goddard Space Flight Center.

Summer Temperatures Arrive Early

Record-breaking heat stifled western U.S. states and Canadian provinces.

NASA’s Spitzer, TESS Find Potentially Volcano-Covered Earth-Size World

Astronomers have discovered an Earth-size exoplanet, or world beyond our solar system, that may be carpeted with volcanoes.

NASA, Rocket Lab Announce Coverage for Second TROPICS Launch

After successfully launching the first pair of small satellites earlier this month from New Zealand, NASA and Rocket Lab are now targeting no earlier than 1:30 a.m. EDT Monday, May 22 (5:30 p.m. NZST), to launch the second pair of storm tracking CubeSats into orbit.

Cyclone Mocha Strikes Myanmar

The storm reached category 5 status before barreling into the state of Rakhine.

NASA Completes Heart of Roman Space Telescope’s Primary Instrument

The heart of NASA’s Nancy Grace Roman Space Telescope was recently delivered to Ball Aerospace for integration into the WFI (Wide Field Instrument). Called the FPS (Focal Plane System), it serves as the core of Roman’s camera.

NASA’s Webb Finds Water, and a New Mystery, in Rare Main Belt Comet

Using Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapor – around a comet in the main asteroid belt for the first time, indicating that water ice from the primordial solar system can be preserved in that region.

NASA Goddard, National Philharmonic Explore Cosmos Through Imagery, Music Collaboration

Awe-inspiring NASA visuals combined with the might of a live symphonic orchestra last week in “Cosmic Cycles,” a multimedia collaboration among the agency’s Goddard Space Flight Center in Greenbelt, Maryland, the National Philharmonic, and composer Henry Dehlinger.
