NASA study eyes soot’s role in 1800s glacier retreat

A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age. The research, published Sept. 3 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate.

NASA’s Hubble spots a cosmic caterpillar

This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what's eating it. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this "wanna-be" star and sculpting the gas and dust into its long shape.

NASA says Saturn moon may have rigid ice shell

An analysis of gravity and topography data from the Saturnian moon Titan obtained by NASA's Cassini spacecraft suggests there could be something unexpected about the moon's outer ice shell.

NASA's space laser to prove increased broadband possible

When NASA’s Lunar Laser Communication Demonstration (LLCD) begins operation aboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission managed by NASA’s Ames Research Center in Moffett Field, Calif., it will attempt to show two-way laser communication beyond Earth is possible, expanding the possibility of transmitting huge amounts of data.

NASA tests limits of 3D printing with powerful rocket engine check

The largest 3-D printed rocket engine component NASA ever has tested blazed to life Thursday, Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust.

NASA to crash test helicopter to study safety

Anybody who says NASA researchers don't know how to have a smashing good time has not met a team at NASA's Langley Research Center in Hampton, Va. They are test engineers whose job it is to make aircraft safer by crashing them.

NASA's Spitzer Telescope celebrates 10 years in space

Ten years after a Delta II rocket launched NASA's Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency's four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.

NASA releases new asteroid mission images

NASA has released new photos and video animations depicting the agency's planned mission to find, capture, redirect, and study a near-Earth asteroid. The images depict crew operations including the Orion spacecraft's trip to and rendezvous with the relocated asteroid, as well as astronauts maneuvering through a spacewalk to collect samples from the asteroid.

NASA's Fermi celebrates 5 years in space, kicks off extended mission

During its five-year primary mission, NASA's Fermi Gamma-ray Space Telescope has given astronomers an increasingly detailed portrait of the universe's most extraordinary phenomena, from giant black holes in the hearts of distant galaxies to thunderstorms on Earth.

NASA's Cassini sees Earth waving at Saturn

People around the world shared more than 1,400 images of themselves as part of the Wave at Saturn event organized by NASA's Cassini mission on July 19 -- the day the Cassini spacecraft turned back toward Earth to take our picture. The mission has assembled a collage from those images which is available here. 

NASA recreates Earth’s northern lights

Scientists have harnessed the tools needed to stage Earth’s most colorful light show, and they have brought the Aurora Borealis into a lab at NASA’s Langley Research Center in Hampton, Va.

NASA links urban population with air pollution

Live in a large city like New York, London, Beijing or Mumbai, and you are likely exposed to more air pollution than people in smaller cities in surrounding areas. But exactly how a city's pollution relates to the size of its population has never been measured, until now.

Chelyabinsk meteor's plume of debris circles the globe

It is unclear what the impact will be on the climate, but three and half hours after the initial explosion, NASA's ozone-mapping satellite detected the plume at 25 miles altitude above the earth's surface moving at about 190 mph eastward.   According to NASA:  

Two moons passing in the Martian night

The larger of the two moons of Mars, Phobos, passes directly in front of the other, Deimos, in a new series of sky-watching images from NASA's Mars rover Curiosity.

NASA tracks Chelyabinsk meteor plume

Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA's Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion.

NASA's Juno is now halfway to Jupiter

NASA's Juno spacecraft is now halfway to Jupiter. 

A small computer vision lab on Mars

To avoid the delays associated with transferring data between Earth and Mars, NASA scientists have developed software that allows the rovers roaming Mars to analyze on the fly.The Jet Propulsion Lab (JPL) in Pasadena, CA built a platform called Onboard Autonomous Science Investigation System (OASIS). OASIS allows the ...

NASA wants to mine asteroids

Over the last hundred years, the human population has exploded from about 1.5 billion to more than seven billion, driving an ever-increasing demand for resources. To satisfy civilization's appetite, communities have expanded recycling efforts while mine operators must explore forbidding frontiers to seek out new deposits, opening mines miles underground or even at the bottom of the ocean.

If we landed on Europa, what would we want to know?

Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA's Voyager 2 spacecraft in 1979 and NASA's Galileo spacecraft in the mid-to-late 1990s.

NASA works on balloon-based telescope

Dr. Rinehart is hoping to change the way scientists study the stars. To do this he needs a group of interns…and one very large balloon.
