Jellyfish galaxy swims into view of NASA's upcoming Webb Telescope
Apr 18, 2019 (SPX)
The newly forming stars in the tail are mysterious because processes common in large groups of galaxies should make it difficult for new stars to emerge. Most g...
Researchers observe formation of a magnetar 6.5 billion light years away
Apr 17, 2019 (SPX)
The research team, which includes Bret Lehmer, assistant professor of physics at the University of Arkansas, analyzed data from the Chandra X-ray Observatory, N...
A new signal for a neutron star collision discovered
Apr 17, 2019 (SPX)
When two neutron stars merge they produce jets of high energy particles and radiation fired in opposite directions. If the jet is pointed along the line of sigh...
Deep space X-ray burst gives astronomers new signal to detect neutron star mergers
Apr 17, 2019 (SPX)
A bright burst of X-rays captured by NASA's Chandra X-ray Observatory in a galaxy located 6.6 billion light years from Earth likely signaled the merger of two n...
Light from exotic particle states
Apr 16, 2019 (SPX)
Researchers at TU Wien have now managed to utilise this: so-called "multi-particle exciton complexes" have been produced by applying electrical pulses to extrem...
Astronomers take first, high-resolution look at huge star-forming region of Milky Way
Apr 16, 2019 (SPX)
The Milky Way region is called CTB 102. It's about 14,000 light years from Earth. It's classified as an HII region, meaning it contains clouds of ionized - char...
'Snowball chamber' helps researchers use supercooled water to search for dark matter
Apr 16, 2019 (SPX)
During the 2019 American Physical Society April Meeting in Denver, Szydagis will describe how this inspired him to explore whether a subatomic particle like dar...
Scientists from NUST MISIS create a super-fast robot microscope to search for dark matter
Apr 15, 2019 (SPX)
The microscopes' speed growth will help scientists in many fields: medicine, nuclear physics, astrophysics, neutrino physics, archeology, geology, volcanology, ...
NASA's Webb Telescope Mirrors Utilize Innovative Space Shielding
Apr 12, 2019 (SPX)
Intentionally chilling the telescope mirrors and instruments with innovative technologies and intelligent spacecraft design allows them to be far more sensitive...
Fireworks of blue lightning and gamma rays above thunderclouds
Apr 10, 2019 (ESA)
The first measurements from the facility that is flying 400 km above Earth outside Europe's Columbus laboratory, reveal how so-called 'terrestrial gamma-flashes...
UCF researchers develop way to control speed of light, send it backward
Apr 09, 2019 (SPX)
The results were published recently in the journal Nature Communications. This achievement is a major step in research that could one day lead to more efficient...
Revolutionary camera allows scientists to predict evolution of ancient stars
Apr 09, 2019 (SPX)
Scientists at the University of Sheffield have been working with HiPERCAM, a high-speed, multicolour camera, which is capable of taking more than 1,000 images p...
Researchers pinpoint origin of photons in mysterious gamma-ray bursts
Apr 08, 2019 (SPX)
Gamma-ray bursts are the most powerful electromagnetic phenomenon observed in the universe, releasing as much energy in just a second or so as the sun will rele...
Dark matter experiment finds no evidence of axions
Apr 08, 2019 (SPX)
Axions are particularly unusual in that they are expected to modify the rules of electricity and magnetism at a minute level. In a paper published in Physical R...
Dark Energy Instrument's lenses see the night sky for the first time
Apr 08, 2019 (SPX)
Just hours later, scientists produced the first focused images with these precision lenses - the largest is 1.1 meters in diameter - during this early test spin...
Simulations find mechanism of brightest flashes in Universe
Apr 08, 2019 (SPX)
Gamma-ray bursts release as much energy in a second or so as the Sun will release over its entire lifetime. Scientists now know that one of the types, long burs...
Heavy Metal Planet Fragment Survives Destruction from Dead Star
Apr 05, 2019 (SPX)
A fragment of a planet that has survived the death of its star has been discovered by University of Warwick astronomers in a disc of debris formed from destroye...
Galaxies Lacking Dark Matter Do in Fact Exist
Apr 04, 2019 (SPX)
Dark matter is a mysterious, invisible substance that typically dominates the makeup of galaxies; finding an object that's missing dark matter is unprecedented,...
Subaru Telescope helps find dark matter is not made up of tiny black holes
Apr 04, 2019 (SPX)
Scientists know that 85 per cent of the matter in the Universe is made up of dark matter. Its gravitational force prevents stars in our Milky Way from flying ap...
Scientists trace origins of photons emitted by gamma ray bursts
Apr 03, 2019 (UPI)
First discovered in 1967, long duration gamma-ray bursts, or GRBs, are extremely powerful explosions. For decades, scientists struggled to explain the high-ener...
