For the first time, astronomers say they may have caught dark matter in the act, not through its gravitational pull but by ...

For more than a decade, NASA’s Fermi Gamma-ray Space Telescope has quietly mapped the high-energy sky, searching for subtle ...

The popular consensus among scientists is that the universe will continue expanding until the bitter end. A team of researchers is now pumping the brakes on that idea. A new theory promises to ...

Very early dark energy (vEDE) may have accelerated the universe’s expansion just 380,000 years after the Big Bang, according to newly published research. This proposed form of dark energy would have ...

Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a very different structure than comets in the solar system. Hydroxyl compounds ...

An anomaly in the temperature of the universe has long stumped physicists, and a new analysis of data from several radio telescopes has only deepened the mystery of what is causing it. This weird ...

Abstract: In this study, a broadband microwave power detector based on an energy-harvesting metasurface is proposed, enabling efficient detection of incident microwave power density via ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...
