Researchers found that emissions of the powerful greenhouse gas dropped for several years near the nation’s second-largest metropolitan area.

Events on the Sun helped unleash beautiful displays of nighttime lights seen on Earth.

Researchers with the U.S. Department of Veterans Affairs are using NASA Earth observations of smoke and other air pollution to study the health impacts on veterans who were deployed to Afghanistan, Iraq, and other areas of Southwest Asia in the years after September 11, 2001.

The mountainous islands in the South Indian Ocean disrupt the flow of air, which can have a ripple-like effect on the clouds.

Cloud vortices leave a fingerprint of atmospheric motion near the Canary Islands.

NASA is preparing for the launch of an instrument that will provide new insight into air quality in North America, observing air pollution from space more frequently and in greater detail than previous space-based instruments. It will also reveal disparities in pollution exposure.

NASA research finds that a combination of windblown dust and human-caused particle pollution was associated with nearly 3 million premature deaths in 2019.

The two agencies are partnering on a satellite to understand the effects of different types of particle pollution on human health.

A pilot project has used satellite measurements to estimate emissions and removals of carbon dioxide in individual nations.

Astronauts and sky watchers oohed and aahed as the night sky lit up with pulsating displays of reds, greens, and purples.

Air pollution is an existential threat to millions of Americans with asthma and other health issues. Responding to that threat, NASA and the Smithsonian Astrophysical Observatory are innovating to improve observations of air quality in North America.

In the wake of a cold front, strong winds lofted dust into the air over northern Mexico, eastern New Mexico, and northwestern Texas.

When airplanes pass through clouds with supercooled water droplets, they can leave distinctive holes in their wake.
