We previously covered such “gravity telescopes” with the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Kamioka Gravitational Wave Detector (KAGRA). These early 2 nd generation of ...

New observations from the James Webb Space Telescope hint that the universe’s first stars might not have been ordinary fusion ...

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 ...

According to a new Physical Review Letters study, black holes could help solve the dark matter mystery. The shadowy regions ...

Abstract: A dense plasma focus (DPF) is a co-axial plasma railgun, whose discharge ends in a z-pinch phase. The MegaJOuLe neutron imaging radiography (MJOLNIR) DPF is a Lawrence Livermore National ...

Our readers agree that in the unlikely event you were able to approach a neutron star, it would look very smooth and bright ...

Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of ...

Relativistic electron-positron plasmas are ubiquitous in extreme astrophysical environments such as black-hole and neutron-star magnetospheres, where accretion-powered jets and pulsar winds are ...

Astronomers have just detected the brightest cosmic flash ever recorded—an ultra-powerful radio burst from deep space that’s ...
