Meanwhile, we have observed something quite incredible in the data recorded by the detectors of the HAWC observatory: photons coming from a microquasar lying in our galaxy, and yet carrying ...

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 ...

Scientists have long thought that the highest-energy gamma rays in space are forged in the intense furnaces of very active ...

V4641 Sagittarii is what's known as a microquasar, and as the name suggests, it kind of functions like a mini version of a regular quasar. The black hole is smaller, the matter source is smaller ...

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 ...

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 ...

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

An astrophysical object called a microquasar in the Milky Way has been found to emit γ-rays. The discovery shows that these systems accelerate particles to extremely high energies, and could ...
