By zeroing in on the infrared scale, researchers offer details of the black hole jet stream in faraway galaxy M87.

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the mass of our sun into a small volume. Models predict that neutron stars are about a dozen or so miles across, but their exact radius has always been unclear.

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed delayed bursts of energy months after the initial destruction,

The sounds aren't just a scientific curiosity, though. The tenuous gas and plasma that drifts between the galaxies in galaxy clusters – known as the intracluster medium – is denser and much, much hotter than the intergalactic medium outside galaxy clusters.

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole.

The Boys universe is often filled with gross gags, but Gen V season 2 perfectly used its most disturbing power in the finale's big showdown.

Nicknamed the “Black Hole” by the U.S. Navy for its extreme quietness, Russia’s Kilo-class submarine is one of history’s most successful diesel-electric designs. -Born in the Cold War to defend coastal waters,

The concept of two black holes orbiting one another has been theorized for many years, but recent satellite photography may have found a real-life example.
