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 ...
Scientists simulate gravity waves propagating toward space
Just as waves ripple across a pond when a tossed stone disturbs the water's surface, gravity waves ripple toward space from disturbances in the lower atmosphere.
Plants use sixth sense for growth aboard the space station
Although it is arguable as to whether plants have all five human senses – sight, scent, hearing, taste and touch – they do have a unique sense of gravity, which is being tested in space. Researchers with ...
New way to calculate how long it would take to fall through a hole in the Earth
Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface ...
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.
