Astrobiologists claim meteorite carried space algae
GRAIL creates most accurate Moon gravity map (w/ video)
(Phys.org)—Twin NASA probes orbiting Earth's moon have generated the highest resolution gravity field map of any celestial body.
Computer model shows strong magnetic fields may alter alignment of black hole accretion disks and plasma jets
Researchers replicate white dwarf photospheres in lab using X-ray machine
For the first time, astronomers have measured the radius of a black hole
(Phys.org)—The point of no return: In astronomy, it's known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be billions ...
Physicists devise means for observing single atom interference over coherence length
Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale ...
Does antimatter weigh more than matter? Lab experiment to find out the answer
Does antimatter behave differently in gravity than matter? Physicists at the University of California, Riverside have set out to determine the answer. Should they find it, it could explain why the universe ...
Do homing pigeons navigate with gyroscope in brain?
No one knows how homing pigeons do it, but now a team of Swiss and South African scientists have discovered that the bird's navigation is affected by disturbances in gravity, suggesting that they navigate ...
New map exposes previously unseen details of seafloor
Accessing two previously untapped streams of satellite data, scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues have created a new map of the world's seafloor, creating ...
GOCE reveals gravity dip from ice loss (w/ Video)
Although not designed to map changes in Earth's gravity over time, ESA's extraordinary satellite has shown that the ice lost from West Antarctica over the last few years has left its signature.
Lunar explorers will walk at higher speeds than thought
Anyone who has seen the movies of Neil Armstrong's first bounding steps on the moon couldn't fail to be intrigued by his unusual walking style. But, contrary to popular belief, the astronaut's peculiar walk ...
How much gravity is enough? Team studies how astronauts determine 'up' in space
Keeping upright in a low-gravity environment is not easy, and NASA documents abound with examples of astronauts falling on the lunar surface. Now, a new study by an international team of researchers led by ...
Study uncovers forces that hold gravity-defying near-earth asteroid together (Update)
Researchers at UT have made a novel discovery that may potentially protect the world from future collisions with asteroids.
