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 ...
Working out in artificial gravity
Astronauts on the International Space Station (ISS) have a number of exercise options, including a mechanical bicycle bolted to the floor, a weightlifting machine strapped to the wall, and a strap-down treadmill. ...
Lightning research links specific atmospheric conditions to exuberant, luminous displays above thunderstorms
A new study led by Florida Institute of Technology Professor Ningyu Liu has improved our understanding of a curious luminous phenomenon that happens 25 to 50 miles above thunderstorms.
How spacetime is built by quantum entanglement
A collaboration of physicists and a mathematician has made a significant step toward unifying general relativity and quantum mechanics by explaining how spacetime emerges from quantum entanglement in a more ...
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 ...
