After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

Artist's impression of a supermassive black hole surrounded by gas and dust in four different wavelengths of light. Visible light (top right) and low-energy X-rays (bottom left) are blocked by the gas ...

In the heart of our Milky Way galaxy, two gigantic "bubbles" extend roughly 50,000 light-years above and below the galactic center.

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

A new study shows that black holes consume gas which creates an outburst that cools nearby gas for the black hole to consume ...

It's believed that a dead stellar remnant, or white dwarf, could be spinning precariously on the edge of the black hole, causing the explosions of high-energy light. “This would be the closest ...
