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.
Three years of research, led by the Univ. of Leicester in the U.K., has produced a new catalog of x-ray source observations call 3XMM. With the help of the university’s supercomputer, the scientists were able to log 531,261 detections of x-ray emitting objects and 372,728 unique x-ray sources. The catalog will provide a useful dataset for generating large, well-defined samples of celestial objects.
New findings from NASA's Curiosity rover provide clues to how Mars lost its original atmosphere, which scientists believe was much thicker than the one left today. The beauty of these measurements lies in the fact that these are the first really high-precision measurements of the composition of Mars' atmosphere.
Recovery efforts to save the $600 million Kepler mission began Thursday and will last for a week. Mission managers won't know until later this month at the earliest whether the Kepler spacecraft will ever search for Earth-like planets again.
Biotechnology company Zero Gravity Solutiuons aims to utilize the unique effects of extended zero/micro gravity environments available on the International Space Station to promote gene expression and accelerate stem cell research. The company has completed filings required prior to trading of the company’s stock.
Unlike elements like carbon or iron, gold cannot be created within a star. Instead, it must be born in a more cataclysmic event—like one that occurred last month known as a short gamma-ray burst (GRB). Observations of this GRB provide evidence that it resulted from the collision of two neutron stars, and that its unique glow potentially signifies the creation of large amounts of heavy elements, including gold.
In one of the most harrowing spacewalks in decades, an astronaut had to rush back into the International Space Station on Tuesday after a mysterious water leak inside his helmet robbed him of the ability to speak or hear at times and could have caused him to choke or even drown. Italian Luca Parmitano was reported to be fine after the dangerous episode, which might have been caused by an unprecedented leak in the cooling system of his suit.
The next rover to Mars should hunt for signs of ancient life and gather rocks that a future mission could bring back to Earth for the first time, a team of scientists appointed by the U.S. space agency said Tuesday. The scientists' new report outlines ambitious goals for a mission to Mars that NASA wants to launch in 2020.
Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy. This process lies at the heart of giant explosions on the sun.
Two Univ. of Michigan engineering professors are turning to the Kickstarter online community to help fund an interplanetary satellite mission. They are teaming up to create two new technologies in a matter of months, with the goal of using a plasma thruster to push a CubeSat into deep space—something that has never been done before.
Astronomers have for the first time managed to determine the color of a planet outside our solar system, a blue gas giant 63 light-years away. Measuring the planet's color, which is probably created by a turbulent atmosphere of silicate particles, is a significant first. It has never been done before with a planet outside our solar system.
Explore an intriguing spot on Mars. Hunt for ancient signs of Martian life. Bag a bunch of rocks and leave them on the surface for a future mission to possibly return. That's what the next rover to Mars should strive for, a NASA-appointed team said Tuesday. The scientists released a 154-page report outlining ambitious science goals for a red planet mission that NASA wants to launch in 2020.
Soon after the Big Bang, the universe was so dense and so hot that elementary particles felt the existence of gravity strongly. For decades, physicists have attempted to model the laws of quantum gravity to describe this phase of the universe’s evolution. A new mathematical model developed by physicists in Poland surprisingly shows that different elementary particles “experience” the existence of different space-times.
Although researchers had tested NASA’s new polar rover at a beach in Maryland and in the snow in Idaho, the May 6 to June 8, 2013 testing at Summit Camp, the highest spot in Greenland, was the rover’s first polar experience. Equipped with ground-penetrating radar, the robot defed 30 mph gusts and temperatures down to -22 F, demonstrating that it could operate completely autonomously in one of Earth’s harshest environments.
Martian mountain, here Curiosity comes. The NASA rover has officially kicked off its long-delayed road trip to Mount Sharp, a trek that involves rolling over rocky landscapes. Since July Fourth, the six-wheel rover has driven 190 feet to the southwest, leaving behind the spot where it spent the past seven months performing science experiments.
A new study has provided the first conclusive proof of the existence of a space wind first proposed theoretically over 20 years ago. By analyzing data from the European Space Agency’s Cluster spacecraft, researchers have the plasmaspheric wind, so-called because it contributes to the loss of material from the plasmasphere, a donut-shaped region extending above the Earth’s atmosphere.
