A team of scientists at NASA's Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, Calif., has found evidence of past water movement throughout a Martian meteorite, reviving debate in the scientific community over life on Mars.
In 1996, a group of scientists at Johnson led by David McKay, Everett Gibson and Kathie Thomas-Keprta published an article in Science announcing the discovery of biogenic evidence in the Allan Hills 84001(ALH84001) meteorite. In this new stu [...]
The Global Precipitation Measurement (GPM) Core Observatory, a joint Earth-observing mission between NASA and the Japan Aerospace Exploration Agency (JAXA), thundered into space at 1:37 p.m. EST Thursday, Feb. 27 (3:37 a.m. JST Friday, Feb. 28) from Japan.
The four-ton spacecraft launched aboard a Japanese H-IIA rocket from Tanegashima Space Center on Tanegashima Island in southern Japan. The GPM spacecraft separated from the rocket 16 minutes after launch, at an altitude of 247 miles (398 ki [...]
CLOSEHOUSTON -- Chris Ferguson, Boeing's director of Crew and Mission Operations and commander of the final Space Shuttle flight, virtually returned to space recently in the Boeing [NYSE: BA] Crew Space Transportation (CST)-100 simulator to satisfy a NASA testing requirement for the spacecraft.
Ferguson performed manual piloting activities including on-orbit attitude and translation maneuvers, docking and backing away from a virtual International Space Station and a manual re-entry to Earth i [...]
Faster brightening than expected may typify cosmic yardstick Type Ia supernovae
A bright supernova discovered only six weeks ago in a nearby galaxy is provoking new questions about the exploding stars that scientists use as their main yardstick for measuring the universe.
Called SN 2014J, the glowing supernova was discovered by a professor and his students in the United Kingdom on Jan. 21, about a week after the stellar explosion first became visible as a pinprick of light in its galaxy [...]
Active Region 11967 consisted of a major sunspot that released numerous solar flares in early 2014. Above is an image taken by the Solar Optical Telescope (SOT) aboard Hinode in the Calcium II H line on Feb. 7, 2014 at 16:09 UT. Below is a wider view of Active Region 11967 as seen by SDO on Feb.12, 2014, at 01:35 UT.
By studying the sun's magnetic field, scientists hope to shed new light on explosive solar activity that can interfere with satellite communications and electric power transmissi [...]
Venus now appears as planet Earth's brilliant morning star standing above the eastern horizon before dawn. For most, the silvery celestial beacon rose in a close pairing with an old crescent Moon on February 26. But seen from locations in western Africa before sunrise, the lunar crescent actually occulted or passed in front of Venus, also in a crescent phase.
Farther to the east, the occultation occurred during daylight hours. In fact, this telescopic snapshot of the dueling crescents was ca [...]
NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.
Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system.
"The Kepler [...]
More micro-satellites were being released into space Tuesday as part of this week's round of NanoRacks CubeSat deployments. The six-member Expedition 38 crew also worked on more life sciences experiments observing how the human body adapts to long-term microgravity.
The Multi-Purpose Experiment Platform, in the grasp of the Japanese robotic arm outside the Kibo laboratory, released more NanoRacks CubeSats Tuesday. The tiny satellites, about four inches tall, are providing researchers opportun [...]
