The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. Using this computer cloud, an international team analyzed archival data to discover 24 pulsars which has been previously missed by astronomers.
An analysis of gravity and topography data from Saturn's largest moon, Titan, has revealed unexpected features of the moon's outer ice shell. The best explanation for the findings, say scientists, is that Titan's ice shell is rigid and that relatively small topographic features on the surface are associated with large roots extending into the underlying ocean.
As several new private ventures to take people on trips to space come closer to becoming reality, California lawmakers are racing other states to woo the new space companies with cushy incentives. They are debating a bill now in Sacramento that would insulate manufacturers of spaceships and parts suppliers from liability should travelers get injured or killed on a voyage, except in cases such as gross negligence or intentional wrongdoing.
After 20 years of effort, a team of astronomers from three institutions have put to use a new type of telescope camera that makes higher resolution images than ever before. The team has been developing this technology at telescope observatories in Arizona and now has deployed the latest version of these cameras in the high desert of Chile at the Magellan 6.5-m telescope. Several upcoming publications will feature these new images.
On Tuesday, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon which can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.
A new theory by fluid dynamics experts at the Univ. of California, Berkeley, shows how “zombie vortices” help lead to the birth of a new star. In a recent report, a UC Berkeley-led team shows how variations in gas density lead to instability, which then generates the whirlpool-like vortices needed for stars to form.
In the time it takes you to complete a single workday, or get a full night’s sleep, a small fireball of a planet 700 light-years away has already completed an entire year. Researchers have discovered an Earth-sized exoplanet named Kepler 78b that whips around its host star in a mere 8.5 hours, one of the shortest orbital periods ever detected.
In two NASA-funded studies, biofilms made by the bacteria Pseudomonas aeruginosa were cultured on Earth and aboard space shuttle Atlantis in 2010 and 2011 to determine the impact of microgravity on their behavior. After comparing the biofilms grown on the ground with those grown on space station-bound shuttles, study results show for the first time that spaceflight changes the behavior of bacterial communities.
Carrying Earthly greetings on a gold plated phonograph record and still-operational scientific instruments NASA's Voyager 1 has traveled farther from Earth than any other human-made object. And now, researchers say, it has begun the first exploration of our galaxy beyond the Sun's influence. The finding could be, however, somewhat controversial.
A meteor weighing 10,000 metric tons exploded 14 miles above Chelyabinsk, Russia, on Feb. 15, 2013. Unlike similar past events, this time scientists had the sensitive instruments on the Suomi NPP satellite to deliver unprecedented data and help them track and study the meteor plume for months.
Six researchers have spent the past four months living in a small dome on a barren Hawaii lava field at 8,000 feet, trying to figure out what foods astronauts might eat on Mars and during deep-space missions. They emerged on Tuesday with their recipes and without the space suits they were required to wear each time they ventured onto the northern slope of Mauna Loa—an active volcano that last erupted in 1984.
All Nippon Airways and Japan Airlines are checking their Boeing 787 fleets for wiring problems unrelated to battery defects that plagued the aircraft earlier this year. ANA said Wednesday the departure of a 787 plane was delayed over problem wiring for a system to put out engine fires.
A recent arrival to NASA’s Kennedy Space Center in Florida, the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft will have quite a different approach than that taken by recent probes dispatched to the Red Planet. Instead of rolling about on the surface looking for clues to the planet's hidden heritage, MAVEN will orbit high above the surface so it can sample the upper atmosphere for signs of what changed over the eons and why.
Astronomers have solved a 40-year-old mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy. It appears to originate from two dwarf galaxies, but astronomers did not know if one or both galaxies were the source. Hubble Space Telescope’s Cosmic Origins Spectrograph was used to examine the gas and find the answer.
Curiosity Rover team members re-live the dramatic Aug. 6, 2012 landing and the mission's achievements to date in a recent event aired on NASA Television and the agency's website. In the year since inspiring millions of people worldwide with its one-of-a-kind landing in a crater on the Red Planet, Curiosity has achieved its primary scientific objective; finding evidence that ancient Mars could have sustained microbial life.
Mystery fans know that the best way to solve a mystery is to revisit the scene where it began and look for clues. To understand the mysteries of our universe, scientists are trying to go back as far they can to the Big Bang. A new analysis of cosmic microwave background (CMB) radiation data has provided tantalizing new hints of clues as to what might have happened.
Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b and still glowing from the heat of its formation, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.
Kirobo—derived from the Japanese words for "hope" and "robot"—was among five tons of supplies and machinery on a rocket launched Sunday from Tanegashima in southwestern Japan. The childlike robot was designed to be a companion for astronaut Koichi Wakata and will communicate with another robot on Earth, according to developers.
Brown Univ. planetary geologists have an explanation for the formation of more than 600 “double-layer ejecta” (DLE) craters on Mars. The Martian surface was covered with a thick sheet of ice at impact. Ejected material would later slide down steep crater sides and across the ice, forming a second layer.
Traveling to remote locations sometimes involves navigating through stop-and-go traffic, traversing long stretches of highway and a lot of maneuvering. The same can be said for guiding spacecraft to far-flung destinations in space. A NASA technologist has developed a fully automated tool that gives mission planners a preliminary set of detailed directions for efficiently steering a spacecraft to hard-to-reach interplanetary destinations.
The GOES-R Magnetometer Engineering Development Unit at NASA’s Goddard Space Flight Center completed successful boom deployment test at an ATK facility in Goleta, Calif. The magnetometer, which will deploy aboard the boom after launch, will provide measurements of the space environment magnetic field, which controls charged particle dynamics in the outer region of the magnetosphere.
Just as remotely-operated vehicles help humans explore the depths of the ocean from above, NASA has begun studying how a similar approach may one day help astronauts explore other worlds. On June 17 and July 26, NASA tested the Surface Telerobotics exploration concept, in which an astronaut in an orbiting spacecraft remotely operates a robot on a planetary surface.
Boeing Co. has expanded inspections of emergency locator beacons made by Honeywell International to include five more aircraft types after problems were discovered with the transmitters on 787 jets. Boeing remarked in a blog that the aircraft manufacturer is asking operators of 717, Next-Generation 737, 747-400, 767 and 777 airplanes to inspect the battery-operated beacons which activate in a crash to help rescuers find a plane.
After studying data from a pair of NASA probes roaming the harsh space environment within the Van Allen radiation belts, researchers at Los Alamos National Laboratory believe they have solved a lingering mystery about how electrons within Earth’s radiation belt can suddenly become energetic enough to kill orbiting satellites.
On July 17, 2013, the international team which supported and built NASA's Interface Region Imaging Spectrograph, or IRIS, was rewarded for its hard work when the door of the telescope opened to view the mysterious lowest layers of the sun's atmosphere in unprecedented detail. Imaging in ultraviolet light and using a spectrograph, the orbiter has already revealed a multitude of previously unseen structures.
