Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
A brighter method to determine surface gravity of distant stars
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Did Andromeda crash into the Milky Way 10 billion years ago?
(Phys.org) —For many years scientists have believed that our Galaxy, the Milky Way, is set to crash into its larger neighbour, the Andromeda Galaxy, in about 3 billion years' time and that this will be ...
Researchers suggest gas cloud could reveal black holes near center of Milky Way galaxy
Team solves the origin of the Moon's 'mascons' mystery
A mystery of the moon that imperiled astronauts and spacecraft on lunar missions has been solved by a Purdue University-led team of scientists as part of NASA's GRAIL mission.
Physicists suggest possible existence of other kinds of dark matter
Researchers find winds on Uranus and Neptune confined to thin atmosphere layer
Researchers measure Brazil nut effect in reduced gravity
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 ...
