If this new model of the universe is right, there were boson stars and cannibal stars hundreds of millions of years before ...

Cosmologists have traced the Big Bang’s earliest moments with great care, from the explosive inflation that set spacetime in ...

In the blink of an eye after the Big Bang, the universe could have birthed strange new stars and black holes.

XRISM’s observations of GX13+1 revealed a slow, fog-like wind instead of the expected high-speed blast, challenging existing models of radiation-driven outflows. The discovery hints that temperature ...

By constructing these so-called Einstein-Rosen caterpillar wormholes, researchers offer a tangible way to imagine what the inside of a typical black hole might look like. Rather than being smooth or ...

During the 1950s, the study of the cosmos was revolutionized with the introduction of radio astronomy. In the ensuing decades, astronomers detected numerous bright radio sources that they designated ...

A giant star that is still being consumed by a supermassive black hole may have caused the largest flare of its kind ever seen, astronomers say.

The only possibility left was an extraordinary one: a tidal disruption event, or TDE.
