The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

The GWTC 4.0 catalog records 128 new gravitational wave signals, revealing mergers of black holes and neutron stars detected by LIGO.

U.S. artificial intelligence-driven energy storage company Stem Inc said on Friday it has agreed to go public by merging with blank-check acquisition company Star Peak Energy Transition Corp at a ...

When you think of telescopes in space, you probably think of the Hubble Space Telescope and its younger, larger sibling, the ...

A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

The transformation of neutrinos in a neutron star merger could be crucial to shaping the way events of the collision unfold. For the first time, a team of physicists has simulated how neutrinos change ...

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, showers of radiation, and even the building blocks of gold and platinum.

Using the joint Japan Aerospace Exploration Agency (JAXA), European Space Agency (ESA), and NASA X-Ray Imaging and Spectroscopy Mission (XRISM), scientists uncovered a dense but surprisingly slow wind ...

LIGO's 2015 detection confirmed Einstein's theory and sparked a decade of data. Upgraded LIGOs now detect black hole mergers every three days with precision. New 2025 findings confirmed Hawking’s ...
