It's used as a coolant in nuclear power plants and as a desiccant to remove humidity that otherwise would ruin moisture-sensitive products. Found in every cell in the human body, it transmits nerve impulses and regulates blood pressure.
NASA's Mars rover Curiosity completed its first two-day autonomous drive Monday, bringing the mobile laboratory to a good vantage point for pictures useful in selecting the next target the rover will reach out and touch.
In the spirit of Halloween, scientists are releasing a trio of stellar ghosts caught in infrared light by NASA's Spitzer Space Telescope. All three spooky structures, called planetary nebulas, are in fact material ejected from dying stars. As death beckoned, the stars' wispy bits and pieces were blown into outer space.
NASA's first-ever deep space craft, Orion, has been powered on for the first time, marking a major milestone in the final year of preparations for flight. Orion's avionics system was installed on the crew module and powered up for a series of systems tests at NASA's Kennedy Space Center in Florida last week.
Apparently, my U-verse rep is right, getting Internet access is rocket science and I should stop screaming at him. As for its Lunar Laser Communication Demonstration (LLCD), NASA has demonstrated a new record for data transmission using lasers. Communicating with laser sounds so cool, dude!
A new image of the sunward plunging comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the sun warms it. The comet will pass closest to the sun on Nov. 28.
NASA's footage of the first moon landing promised a future of sci-fi heroism that never came to pass, according to a new study.
NASA's Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn's moon Titan.
Astronomers using data from NASA's Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b.
Anyone familiar with the crazy saga of John McAfee can tell you the guy might not be playing with a full deck. The former programmer for NASA who developed the first anti-virus program, he’s also been on the run for some time in connection of the murder of his neighbor in the jungle compound of Belize.
NASA has released its announcement of an open competition for the planetary community to submit proposals for the science and exploration technology instruments that would be carried aboard the agency's next Mars rover, scheduled for launch in July/August of 2020.
Scientists have provided the most comprehensive details yet of the journey energy from the sun takes as it hurtles around Earth's magnetosphere.
Astronomers using NASA's Hubble Space Telescope and Chandra X-ray Observatory and telescopes on the ground may have found the most crowded galaxy in our part of the universe.
NASA's Mars rover Curiosity has resumed a trek of many months toward its mountain-slope destination, Mount Sharp. The rover used instruments on its arm last week to inspect rocks at its first waypoint along the route inside Gale Crater.
The location, originally chosen on the basis of images taken from NASA's Mars Reconnaissance Orbiter, paid off with investigation of targets that bear evidence of ancient wet environments.
It's not easy to simulate millions of miles electronically, but that's what engineers did recently as they tested the all-important communications system the MAVEN spacecraft will use to relay its study results from Mars orbit to Earth-bound researchers.
After almost 9 years in space that included an unprecedented July 4th impact and subsequent flyby of a comet, an additional comet flyby, and the return of approximately 500,000 images of celestial objects, NASA's Deep Impact mission has ended.
Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. The roving laboratory performed extensive tests to search for traces of Martian methane.
Elusive schlieren images of supersonic shockwaves emanating from NASA F-15 and F/A-18 aircraft flying at supersonic speeds were captured during recent pilot proficiency flights.
NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun. New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars.
NASA's Mars rover Curiosity now has a view of a patch of exposed bedrock scientists selected for a few days of close-up study, the first such study since the rover began its long trek to Mount Sharp two months ago.
