A newly expanded image of the Helix nebula lends a festive touch to the fourth anniversary of the launch of NASA's Spitzer Space Telescope.
This image shows the Zaca fire, which continues to burn in the Los Padres National Forest near Santa Barbara, Calif.
A new study co-authored by a JPL researcher shows that sunspot cycles can be used to predict heavy rains, flooding and subsequent outbreaks of disease in East Africa.› Release from Paul Smith's College →
A new tool from the U.S. Geological Survey uses NASA satellite data to depict changes to Earth's surface over the past 30 years.› USGS release →
A key contributor to this new generation of climate change research tools is the Atmospheric Infrared Sounder, or AIRS, instrument on NASA's Aqua spacecraft.
Cassini successfully completed a flyby of Titan on July 19.
Scientists have recently discovered that the planet Saturn is turning 60 - not years, but moons.
JPL will participate in a NASA summer study of a largely unexplored region of Earth's atmosphere that has implications for climate change and atmospheric ozone.
Cassini is getting ready for its next Titan flyby.
The Galaxy Evolution Explorer's ultraviolet eyes have captured a globular star cluster, called NGC 362, in our own Milky Way galaxy.
Astronomers suspect the early Earth was a very harsh place.
Explore hundreds of sweeping images from NASA's Mars Reconnaissance Orbiter with new user-friendly features at the Web site of the mission's high-resolution camera.
The unique abilities of NASA instruments to track tiny particles of air pollution may aid public health efforts.
Cassini's science instruments will conduct observations of Titan during the May 28, 2007, flyby.
Cassini successfully completed a flyby of Titan on April 10, 2007.
JPL's Atmospheric Infrared Sounder instrument on NASA's Aqua spacecraft is being used by scientists to observe atmospheric carbon dioxide. This global map shows concentrations of carbon dioxide in the troposphere (about eight kilometers, or five miles, above Earth).
During Cassini's most recent flyby of Titan on May 12, 2007, the radar instrument imaged a large sea and its coastline, with numerous island groups and mountains.
A new image from NASA's Spitzer Space Telescope shows infant stars "hatching" in the head of Orion, the famous hunter constellation visible from northern hemispheres during winter nights.
Two NASA satellites flew over the center of then Subtropical Storm Andrea Wednesday, May 9, off the U.S. southeast coast. In the CloudSat image (bottom), brighter colors indicate more water in the clouds.
Tholins, complex organic molecules fundamental to prebiotic chemistry, are apparently forming at a much higher altitude, and in different ways than expected, in Titan’s atmosphere. These results appear in this week’s issue of the journal Science.
