Central predictions by GSI scientists on the formation of heavy elements such as gold and platinum in the universe have now been observed astrophysically. For the first time gravitational waves of merging neutron stars were detected. This also puts further focus on the future accelerator facility FAIR, as conditions for further research on neutron stars can be simulated there.
Filling the universe with knots shortly after it popped into existence 13.8 billion years ago provides a neat explanation for why we inhabit a three-dimensional world. That is the basic idea advanced by an out-of-the-box theory developed by an international team of physicists.
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on Aug. 17, 2017.
NASA-NOAA's Suomi NPP satellite provided a visible picture of newly formed Tropical Storm Lan in the Northwestern Pacific Ocean.
NASA's Terra satellite passed over Tropical Storm Khanun after it had passed over southern China and began dissipating in the Gulf of Tonkin.
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.
New research published in Science details perhaps one of the biggest discoveries so far in the field of astrophysics: the merger of two neutron stars. Two graduate students and two professors at the University of Notre Dame contributed to studies published on the collision.
On August 17, 2017, scientists made the first direct observation of a merger between two neutron stars -- the dense, collapsed cores that remain after large stars die in a supernova explosion. The merger is the first cosmological event observed in both gravitational waves -- ripples in the fabric of spacetime -- and the entire spectrum of light, from gamma rays to radio waves. University of Maryland researchers played key roles in detecting signals of the historic event.
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.
Four Northwestern University astronomers are part of an international research collaboration that is the first to detect the spectacular collision of two neutron stars using both gravitational waves and light. The discovery ushers in an exciting new era in astronomy -- multi-messenger astronomy with gravitational waves -- less than two years after the first detection of gravitational waves opened a new window onto the universe. The astronomers hold leading roles on both sides of discovery, in gravitational-wave astronomy and electromagnetic astronomy.
