Researchers have discovered something groundbreaking in the world of astrophysics—an incredible system where not one, but a ...

For a long time, astronomers believed that extremely high-energy radiation was produced only in the jets of active galaxies, far from Earth. But new observations from the High-Altitude Water Cherenkov ...

Gamma rays around this energy level are known to zip around the cosmos, but scientists thought they mostly originated in ...

Astronomers have made a shocking discovery that’s rewriting the way we think about cosmic powerhouses. While scientists ...

In a new study, scientists have found that a huge black hole - with a mass of about six Suns - is feasting upon a giant star and releasing intense radiation in deep space. The star is as big as three ...

The illustration shows how the gold nanorods heat up when illuminated with NIR light. At temperatures above 120 degrees Celsius, the gold rods begin to change shape, and their optical properties ...

Stellar-mass black holes typically form after a star goes supernova and collapses. However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture. This black ...

An ultrashort pulse of light excites molecules at specific near-infrared wavelengths. In this setup, the molecules inside a small container represent the sample being studied, while the surrounding ...

Sources of high-energy cosmic rays in the vicinity of the microquasar V4641 Sag, on the left with energies above a teraelectronvolt, on the right – hundreds of teraelectronvolts. The location of the ...

The review encompassed genetic histories for 23 common mammals in Europe, including rodents, red squirrels, insectivores, wild boar and bears. Refugia comprises areas of high genetic diversity ...
