In a special collection of research papers published Sep. 9 in the Journal of Geophysical Research: Planets, the OSIRIS-REx science team reports detailed observations that reveal Bennu is shedding material on a regular basis.
A new study published this month in JGR Planets posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its surface as the object nears the Sun. The study's primary author is Southwest Research Institute scientist Dr. William Bottke, who used data from NASA's OSIRIS-REx mission.
NASA's InSight mission provides data from the surface of Mars. Its seismometer, equipped with electronics built at ETH Zurich, not only records marsquakes, but unexpectedly reacts to solar eclipses as well. When the Martian moon, Phobos moves directly in front of the sun, the instrument tips slightly to one side. This miniscule effect could aid researchers in determining the planet's interior.
Cosmologists have zoomed in on the smallest clumps of dark matter in a virtual universe - which could help us to find the real thing in space.
Researchers have detected a signal from what may be the most massive black hole merger yet observed in gravitational waves. The product of the merger is the first clear detection of an 'intermediate-mass' black hole, with a mass between 100 and 1,000 times that of the sun.
A team led by the University of Colorado Boulder is pioneering a new solution to the problem of spring cleaning on the moon: Why not zap away the grime using a beam of electrons?
Electrifying research by Clemson University scientists could lead to the creation of lighter, faster-charging batteries suitable for powering a spacesuit, or even a Mars rover.
In a paper in Physical Review D, a University of California, Irvine-led team reports that - through an analysis of the Fermi data and an exhaustive series of modeling exercises - they were able to determine that an observed excess of gamma rays could not have been produced by what are called weakly interacting massive particles, most popularly theorized as the stuff of dark matter.
It's hard to get a good night's sleep in space. An evaluation of astronauts serving on the Mir space station found that they experienced shorter sleep durations, more wakefulness, and changes in the structure of their sleep cycles while in microgravity.
For the first time, researchers in Germany sent perovskite and organic solar cells on a rocket into space. The solar cells withstood the extreme conditions in space, producing power from direct sunlight and reflective light from the Earth's surface. The work, published August 12 in the journal Joule, sets the foundation for future near-Earth application as well as potential deep space missions.
