Detergent-like Molecule Recycles Itself in Atmosphere

Hydroxyl radicals are critical for offsetting concentrations of methane in the air.

Greenhouse Gas ‘Detergent’ Recycles Itself in Atmosphere: NASA Study

A tiny compound in the atmosphere that acts as a 'detergent' to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions.

California Fires Smoke Spews Aerosols Into an Already Saturated Sky

New research using data collected during NASA airborne science campaigns shows how smoke from wildfires worldwide could impact the atmosphere and climate much more than previously thought.

Ozone Hole is Big, But Tempered by CFC Reductions

The hole in the ozone layer over Antarctica was slightly above average size in 2018, but smaller than expected for the weather conditions.

NASA Brings its Science and Supercomputing Advances to SC18

From designing rocket launch pad components and safer rotorcraft to improving flood and drought forecasts to modeling the formation of planetary disks, NASA will highlight supercomputing advances at SC18, the International Conference for High Performance Computing, Networking, Storage and Analysis, Nov. 12 to 15 in Dallas.

Ozone Hole Modest Despite Optimum Conditions for Ozone Depletion

Declining levels of ozone-depleting chemicals in the Antarctic stratosphere helped keep the ozone hole that forms over the continent each September at slightly above average size in 2018, NOAA and NASA scientists reported today.

Smokier and Smokier Skies in India

Since 2003, the number of November crop fires in northern India has increased significantly.

NASA Team Demonstrates “Science on a Shoestring” with Greenhouse Gas-Measuring Instrument

A novel instrument that has already proven its mettle on field campaigns will attempt to measure atmospheric greenhouse gases from an occultation-viewing, low-Earth-orbiting CubeSat mission called Mini-Carb early next year — marking the first time this type of instrument has flown in space.

Smoke Plumes Tower Over California

Several fires are spreading noxious gases and particles across the state—and to a lesser degree much of the country.

NASA Goddard’s Science Jamboree Connects Disciplines and Interns

The Goddard Science Jamboree provides an opportunity for interns and senior scientists alike to learn more about the science happening in other disciplines in one room.

NASA Joins Effort to Sniff Out Ozone in the Northeast

A scientific investigation is looking into how troublesome ozone forms and how it's being transported around the Long Island Sound.

Hazardous Pre-Monsoon Dust Pollution

The most intense dust storms usually occur just before monsoon season. But this year has been worse than usual.

Cloudy with a Chance of Chemistry

The most important question at the daily briefing for NASA’s Atmospheric Tomography, or ATom, mission is: What are we flying through next?

NASA Scientist to Discuss 'Mapping the Blue Marble: Using Space-Based Observations for Improved Global Water Security and Sustainability' at Library of Congress Lecture

The public is invited to a free talk called 'Mapping the Blue Marble: Using Space-Based Observations for Improved Global Water Security and Sustainability,' with Dr. John Bolten.

NASA Satellite Images Show Fissures from Hawaii Volcano

The eruption of Kilauea Volcano on the island of Hawaii triggered a number of gas- and lava-oozing fissures in the East Riff Zone of the volcano.

Peter Pantina, Research Scientist, Sees Inside Clouds Around the World

Peter Pantina see inside clouds around the world.

2020 Decadal Survey Missions: At a Glance

Any telescope that reaches the launch pad in the 2030s likely will look much different than the concepts four teams are currently studying to inform the 2020 Decadal Survey for Astrophysics, but the studies do offer a roadmap.

NASA Teams Study the Agency’s Future in Astrophysics; Tackle Formidable Technology Challenges

As in past decades, the agency won’t make that decision in a vacuum or without understanding the technical obstacles, which are formidable.

NASA's World Tour of the Atmosphere Reveals Surprises Along the Way

The airborne Atmospheric Tomography world-wide survey has gotten an up close look at Earth's atmosphere.

Celebrating 60 Years of Groundbreaking U.S. Space Science

Sixty years ago, the U.S. launched Explorer 1, rocketing into the Space Age.

Explorer 1: The Beginning of American Space Science

Sixty years ago, the hopes of Cold War America soared into the night sky as a rocket lofted skyward above Cape Canaveral, a soon-to-be-famous barrier island off the Florida coast.

GeoCarb: A New View of Carbon Over the Americas

A new NASA Earth satellite mission may transform our understanding of the global carbon cycle by mapping key carbon gases from a new vantage point: geostationary orbit.

NASA Study: First Direct Proof of Ozone Hole Recovery Due to Chemicals Ban

For the first time, direct observations of the Antarctic ozone hole show evidence of recovery due to the 1987 Montreal Protocol's ban on a class of potent, ozone-depleting chemicals.

Agricultural Fires in Africa Stretch the Whole of the Continent

The VIIRS instrument on the Suomi NPP satellite collected this image which detected hundreds upon hundreds of fires burning in Central Africa. Most likely these fires are agricultural in nature.
