(American Friends of Tel Aviv University) Tel Aviv University researchers have confirmed that gravitational 'ripples in space' occur after the collision of neutron stars, very small (typically 18 miles across) and very dense bodies that are the remains of a massive star after a supernova explosion.
(NASA/Goddard Space Flight Center) NASA's Terra satellite passed over Tropical Storm Khanun after it had passed over southern China and began dissipating in the Gulf of Tonkin.
(NASA/Goddard Space Flight Center) NASA-NOAA's Suomi NPP satellite provided a thermal view of the clouds in hurricane Ophelia as it lashed Ireland. The Global Precipitation Measurement mission core satellite provided a look at the rainfall that was affecting the Emerald Isle.
We’ve taken the first pictures of neutron stars colliding 130 million light years away. The resulting gravitational waves may solve some big cosmic mysteries
(University of Sydney) An Australian group was the first in the world to confirm the radio emission from a gravitational wave. University of Sydney Associate Professor Tara Murphy was in the US with a collaborator when they saw the gravitational wave announcement come through on the private LIGO email list. Show More Summary
Proof that celestial collisions called kilonovas create gold is the first wonder to arise from coordinated observations – expect more to come If you are wearing a piece of gold jewellery, take a good, hard look at it and consider this:...Show More Summary
In the world of astrophysics, Aug. 17, 2017, was a red-letter day. “This is a game-changer for astrophysics,” said UC Santa Barbara faculty member Andy Howell, who leads the supernova group at the Las Cumbres Observatory (LCO). “A hundred years...
“It is tremendously exciting to experience a rare event that transforms our understanding of the workings of the universe,” says France A. Córdova, director of the National Science Foundation (NSF), which funds LIGO. “This discovery realizes a long-standing goal many...
ESO’s fleet of telescopes in Chile have detected the first visible counterpart to a gravitational wave source. These historic observations suggest that this unique object is the result of the merger of two neutron stars. The cataclysmic aftermaths of this...
"We haven't altered the laws of physics," says Mikael Afzelius, a member of the applied physics group at the University of Geneva. "What has changed is how we handle the flow of data." Quantum theory predicts that a vast number...
The astrophysics world is abuzz after the first-ever observation of two neutron stars merging in a cataclysmic crash that left a rich trail of debris for scientists to comb through.
ESA’s Integral satellite recently played a crucial role in discovering the flash of gamma rays linked to the gravitational waves released by the collision of two neutron stars.
When disaster strikes, a group of international space agencies pools its resources and expertise to support relief efforts on the ground. For the next six months, ESA will be leading the International Charter Space and Major Disasters as it brings information from satellites to the aid of the vulnerable.
Launched last week, Europe’s Sentinel-5P satellite – the first Copernicus mission dedicated to monitoring the air we breathe – is in excellent health.
The Hubble space telescope and around 70 other observatories have witnessed one of the biggest and rarest explosions in the universe, as two incredibly dense neutron stars collided. The post Hubble and fleet of telescopes watch kilonova as neutron stars collide appeared first on Skymania News. Show More Summary
(Rochester Institute of Technology) Rochester Institute of Technology played a significant role in the breakthrough discovery of colliding neutron stars, cosmic collision detected in gravitational waves and in light. "We can probably...Show More Summary
(DOE/Fermi National Accelerator Laboratory) A team of scientists using the Dark Energy Camera (DECam), the primary observing tool of the Dark Energy Survey, was among the first to observe the fiery aftermath of a recently detected burst of gravitational waves, recording images of the first confirmed explosion from two colliding neutron stars ever seen by astronomers.
(National Institutes of Natural Sciences) Astronomers have tracked down the source of a gravitational wave and discovered the first observed kilonova: a nuclear furnace 100 million times brighter than the Sun producing thousands of times the entire mass of the Earth in heavy elements such as precious metals.
Extraordinary event has been ‘seen’ for the first time, in both gravitational waves and light – ending decades-old debate about where gold comes from The collision of a pair of neutron stars, marked by ripples through the fabric of space-time...Show More Summary
