NASA is remembering 17 astronauts who were killed in the line of duty and dozens more who have died since the agency's beginning. Dozens of people attended a remembrance ceremony today at NASA's Marshall Space Flight Center in Huntsville.
Researchers have proposed a new fundamental particle that could explain why no one has managed...
A newly discovered solar system— with five small rocky planets— makes ours look like a baby....
The speckled object depicted here is Callisto, Jupiter’s second largest moon. Similar in appearance to a golf ball, Callisto is covered almost uniformly with pockmarks and craters across its surface, evidence of relentless collisions. In fact, Callisto is the most heavily cratered object in the Solar System.
New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the material properties that determined planets' formation and evolution processes.
On Nov. 12, 2014, the Rosetta mission made history when its Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this exciting technical achievement gained lots of headlines, it was only the beginning for researchers back on Earth who are receiving and analyzing comet data. The latest chapter in the story provides the closest and most detailed look at a comet that scientists have ever seen.
Scientists plumbing the depths of the ocean have made a surprise finding that could change the way we understand supernovae, exploding stars way beyond our solar system. The researchers have analyzed extraterrestrial dust, thought to be from supernovae, that has settled on ocean floors to determine the amount of heavy elements created by the massive explosions.
SpaceX has released dramatic footage of its booster rocket trying to land on a floating ocean barge after a launch — an unprecedented attempt that ended in a fiery explosion. The video shows the 14-story rocket hitting the football field-sized barge at an angle, lighting up the night sky off the Florida coast.
A strange phenomenon has been observed by astronomers right as it was happening — a “fast radio burst.” The eruption was described as an extremely short, sharp flash of radio waves from an unknown source in the universe.
Knowing where agricultural land is located is crucial for regional and global food security planning, and information on field size offers valuable insight into local economic conditions. Two new global maps provide a significant step forward in global cropland information on these two topics.
Two teams of astronomers have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars— extremely luminous objects powered by supermassive black holes— regulate the formation of stars and the build-up of the most massive galaxies. They found that a quasar spits out cold gas at speeds up to 2,000 kilometers per second, and across distances of nearly 200,000 light years.
The Beagle-2 Mars lander, which has been lost on Mars since 2003, has been found in images taken by a NASA orbiter at the Red Planet. Beagle-2 was released from its mother craft on Dec. 19, 2003, and was due to land six days later. But nothing was heard from the lander after its scheduled touchdown, and searches for the lander were fruitless.
Asteroids may be a byproduct of planet formation rather than planetary building blocks. Research suggests collisions of planetary embryos– the seeds to the planets in our solar system that existed 4 billion years ago– could be the origin of the material that formed asteroids.
NASA evacuated astronauts from its side of the International Space Station (ISS) today after an alarm indicated a possible toxic leak. Officials later said a false sensor reading or computer problem likely set off the alarm, rather than an actual leak of ammonia coolant.
Scientists have developed an extremely sensitive device that can detect life forms by sensing the slightest motion. The chemistry-free system can be used to rapidly test antibiotics or even to search for life on other planets.
It is said that great things can come in small packages. In this case, one key to keeping astronauts healthy on long-duration space missions may be found in a tiny roundworm barely a millimeter long. Studies on the ISS help researchers seek clues to physiological problems found in astronauts by studying millimeter-long roundworms.
The Operational Land Imager on Landsat 8 captured this view of a phytoplankton bloom near Alaska’s Pribilof Islands on Sept. 22, 2014. The Pribilofs are surrounded by nutrient-rich waters in the Bering Sea. The milky green and light blue shading of the water indicates the presence of vast populations of microscopic phytoplankton— mostly coccolithophores, which have chalky calcite scales.
A shipment of much-needed groceries and belated Christmas presents finally arrived Monday morning at the International Space Station.
The editors of Laboratory Equipment want you to start your week with a smile of your face. With years of science experience, we've heard every science joke there is. So, here’s a science joke you might like. Q: Why do you have to be rich to be an astronaut?
Some of the stars appear to be missing in an intriguing new image of space. But the black gap in this glitteringly beautiful star field is not really a gap, but rather a region of space clogged with gas and dust. Such clouds are the birthplaces of future stars.
Splash form tektites are tiny pieces of natural glass created out of spinning drops of molten rock flung from the earth during an extra-terrestrial impact. They come in a myriad of shapes and the formation of these shapes has been the subject of scientific investigation for centuries. Now, using magnetic levitation to imitate weightlessness, researchers have manufactured solid wax models of these shapes.
Stars slow down as they age, and their ages are well-kept secrets. Now, astronomers are attempting to construct a clock that can measure accurate and precise ages of stars from their spins.
SpaceX called off a supply flight to the International Space Station today because of rocket trouble, another delay in the delivery of groceries and overdue Christmas presents. The countdown was halted just over a minute before launch when a steering mechanism in the rocket malfunctioned.
Devising a way to one day land astronauts on Mars is a complex problem and NASA scientists think something as simple as a child's toy design may help solve the problem. Engineers have been working to develop an inflatable heat shield that looks a lot like a super-sized version of a stacking ring of doughnuts for infants.
NASA's Dawn spacecraft has entered an approach phase in which it will continue to close in on Ceres, a Texas-sized dwarf planet never before visited by a spacecraft. Dawn launched in 2007 and is scheduled to enter Ceres orbit in March 2015.
German cities emit several times less light per capita than comparably sized American cities, according to new research. The size of the gap grew with city size, as light per capita increased with city size in the U.S. but decreased with city size in Germany.
A new paper argues that the major cause of fragmentation for small asteroids, around one hundred meters in size, is not collisions with other asteroids but rapid rotation induced by radiation.
New video recorded during the return of NASA’s Orion through Earth’s atmosphere this month provides a taste of the intense conditions the spacecraft, and the astronauts it carries, will endure when they return from deep space destinations on the journey to Mars.
