Rotating black holes may serve as gentle portals for hyperspace travel
Jan 11, 2019 (The Conversation)
Black holes are perhaps the most mysterious objects in the universe. They are the consequence of gravity crushing a dying star without limit, leading to the for...
NICER maps 'light echoes' of new black hole
Jan 10, 2019 (SPX)
"NICER has allowed us to measure light echoes closer to a stellar-mass black hole than ever before," said Erin Kara, an astrophysicist at the University of Mary...
X-ray pulse near event horizon as black hole devours star
Jan 10, 2019 (SPX)
The event, known as a tidal disruption flare, for the black hole's massive tidal pull that tears a star apart, created a burst of X-ray activity near the center...
XMM-Newton captures cries of star shredded by black hole
Jan 10, 2019 (SPX)
Black holes are thought to lurk at the centres of all massive galaxies throughout the universe and are inextricably tied to the properties of their host galaxie...
Gemini: cosmic telescope zooms in on beginning of time
Jan 10, 2019 (SPX)
"If it weren't for this makeshift cosmic telescope, the quasar's light would appear about 50 times dimmer," said Xiaohui Fan of the University of Arizona, who l...
Black hole evolves as it wolfs down stellar material
Jan 10, 2019 (SPX)
Now astronomers from MIT and elsewhere have detected "echoes" within this burst of X-ray emissions, that they believe could be a clue to how black holes evolve ...
Astronomers uncover brightest quasar in early universe
Jan 10, 2019 (SPX)
With the help of multiple, world-class telescopes in Hawaii - Gemini Observatory, James Clerk Maxwell Telescope (JCMT), United Kingdom Infra-Red Telescope (UKIR...
UA student simulates thousands of black holes to test Einstein
Jan 08, 2019 (SPX)
Medeiros has developed a diagnostic tool that astronomers can use to compare upcoming observations of supermassive black holes by the Event Horizon Telescope to...
A competing state of matter in superconducting material uncovered
Jan 03, 2019 (SPX)
"Superconductivity is a strange state of matter, in which the pairing of electrons makes them move faster," said Jigang Wang, Ames Laboratory physicist and Iowa...
The coolest experiment in the universe
Jan 01, 2019 (JPL)
The Cold Atom Lab (CAL) is the first facility in orbit to produce clouds of "ultracold" atoms, which can reach a fraction of a degree above absolute zero: -459+...
Beyond the black hole singularity with loop quantum gravity
Jan 01, 2019 (SPX)
Loop quantum gravity, originated at Penn State and subsequently developed by a large number of scientists worldwide, is opening up a new paradigm in modern phys...
Precision experiment first to isolate, measure weak force between protons, neutrons
Jan 01, 2019 (SPX)
Through a unique neutron experiment at the Department of Energy's Oak Ridge National Laboratory, experimental physicists resolved the weak force between the par...
World welcomes 2019 with fireworks and festivities
Jan 01, 2019 (AFP)
Monday's celebrations kicked off with Sydney hosting its biggest-ever pyrotechnics display and lighting up its harbour-front skyline for a full 12 minutes. More...
Cosmologists claim universe is riding on an expanding bubble in an extra dimension
Jan 01, 2019 (UPI)
In a new paper published in the journal Physical Review Letters, scientists claim the universe is riding on an expanding bubble in an extra dimension. The new m...
ESA sets clock by distant spinning stars
Jan 01, 2019 (ESA)
Operating since the end of November, this pulsar-based timing system is hosted in the Galileo Timing and Geodetic Validation Facility of ESA's ESTEC establishme...
Our universe: An expanding bubble in an extra dimension
Jan 01, 2019 (SPX)
We have known for the past 20 years that the Universe is expanding at an ever accelerating rate. The explanation is the "dark energy" that permeates it througho...
Electrically charged higgs versus physicists: 1-0 until break
Dec 27, 2018 (SPX)
At the European Organization for Nuclear Research CERN near Geneva, the Large Hadron Collider's second run of collisions and collecting data on particles and th...
Physicists develop new theory to answer fundamental questions about black holes
Dec 21, 2018 (SPX)
Einstein's theory of general relativity predicted that once an object falls inside an event horizon, it ends up at the center of the black hole called a singula...
Unique insights into an exotic matter state
Dec 19, 2018 (SPX)
By now, they are well researched, and theoretical physics has determined the electronic structure of the majority of matter. However, how matter behaves under e...
Mystery of coronae around supermassive black holes deepens
Dec 19, 2018 (SPX)
It has long been known that the supermassive black holes that lie at the centers of galaxies, sometimes outshining their host galaxies, have coronae of superhea...
