NASA Approves Continuation of ICESat-2 After 3+ Years of Big Results

As ICESat-2 mission receives the green light to continue operation after successfully completing its three-year primary mission, scientists highlight what it has already discovered.

Brilliant Color in the Black Sea

As spring 2022 turned the page to summer, phytoplankton turned the seawater from dark to vivid.

NASA Experiment Suggests Need to Dig Deep for Evidence of Life on Mars

According to a new NASA laboratory experiment, rovers may have to dig about 6.6 feet (two meters) or more under the Martian surface to find signs of ancient life because ionizing radiation from space degrades small molecules such as amino acids relatively quickly.

Floods Swamp Bangladesh

Monsoon rains have overwhelmed villages, inundated crops, and displaced hundreds of thousands of people.

NASA's Lunar Reconnaissance Orbiter Spots Rocket Impact Site on Moon

Astronomers discovered a rocket body heading toward a lunar collision late last year. Impact occurred March 4, with NASA's Lunar Reconnaissance Orbiter later spotting the resulting double crater.

Catastrophic Flooding in Yellowstone

Snowmelt and heavy rain caused historically high water that destroyed homes, roads, and bridges, and isolated some of the national park’s gateway communities.

NASA’s Webb to Uncover Riches of the Early Universe

NASA’s next flagship observatory, the James Webb Space Telescope, is poised to add new riches to our wealth of knowledge not only by capturing images from galaxies that existed as early as the first few hundred million years after the big bang, but also by giving us detailed data known as spectra.

NASA’s Astronomy Picture of the Day Recognized for Decades of Outreach

NASA's APOD has been honored by the International Astronomical Union for decades of outreach.

Keith Gendreau: Keeping an Open Mind About Zombie Stars

Keith Gendreau brings an open mind and love for connecting ideas to his role as the principal investigator for NASA's NICER mission.

Hubble Snaps a Sea of Sequins

This star-studded image shows the globular cluster Terzan 9 in the constellation Sagittarius, toward the center of the Milky Way.

Alaska Ablaze

Dozens of wildfires, including the largest tundra fire on record for the Yukon, are burning across the state.

Dead Star Caught Ripping Up Planetary System

Both rocky and icy bodies were identified among the debris on the surface of a white dwarf star

NASA Telescope to Help Untangle Galaxy Growth, Dark Matter Makeup

NASA’s Nancy Grace Roman Space Telescope will study wispy streams of stars that extend far beyond the edges of many galaxies. Astronomers will use these observations to explore how galaxies grow and the nature of dark matter.

Update on NASA's TROPICS-1 Mission

While we are disappointed in the loss of the two TROPICS CubeSats, the mission is part of NASA’s Earth venture program, which provides opportunities for lower-cost, higher risk missions. Despite a loss of the first two of six satellites, TROPICS will still meet its science objectives with the four remaining CubeSats distributed in two orbits.

Hubble Investigates an Enigmatic Star Cluster

Unlike most globular clusters, Ruprecht 106 may be what astronomers call a single population globular cluster.

Hubble Determines Mass of Isolated Black Hole Roaming Our Milky Way Galaxy

Astronomers estimate that 100 million black holes roam among the stars in our Milky Way galaxy, but they have never conclusively identified an isolated black hole.

NASA to Launch 6 Small Satellites to Monitor, Study Tropical Cyclones

This month, NASA is launching the first two of six small satellites to study the formation and development of tropical cyclones almost every hour – about four to six times more often than is possible with current satellites.

Hear 'Sounds of the Sea' in Ocean Scientists' Music Project

This World Oceans Day enjoy a moment of zen with a symphonic tour of the ocean.

NASA, FEMA Release Comprehensive Climate Action Guide

NASA and the Federal Emergency Management Agency (FEMA) have released a guide which provides resources for adapting to and mitigating impacts of climate change. The guide, Building Alliances for Climate Action, includes various perspectives, stories, insights, and resources to help individuals and organizations make informed decisions.

NASA-funded Study: Gulf of Maine’s Phytoplankton Productivity Down 65%

The Gulf of Maine is growing increasingly warm and salty, due to ocean currents pushing warm water into the gulf from the Northwest Atlantic, according to a new NASA-funded study. These temperature and salinity changes have led to a substantial decrease in the productivity of phytoplankton that serve as the basis of the marine food web.

A Burst of Saharan Dust

A fresh supply of airborne particles took off from northwest Africa in early June 2022.

NASA Invites Media to Learn About Mission Studying Thunderstorms

NASA will host a media teleconference at 10 a.m. CDT Tuesday, June 7, to discuss research about intense summer thunderstorms over the central United States and their effects on Earth’s atmosphere and climate change. A replay of the call will be posted on the agency’s website as soon as possible.

Hubble Gazes at a Dazzling Star Cluster

The muted red tones of the globular cluster Liller 1 are partially obscured in this image by a dense scattering of piercingly blue stars.

NOAA Shares Flashy First Imagery from GOES-18 Lightning Mapper

The Geostationary Lightning Mapper (GLM) instrument, onboard NOAA’s GOES-18 satellite, is now providing striking lightning observations of the Western Hemisphere. GOES-18 launched on March 1, 2022.

NASA’s DAVINCI Mission To Take the Plunge Through Massive Atmosphere of Venus

In a recently published paper, NASA scientists and engineers give new details about the agency’s DAVINCI mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.
