If the Big Bang created miniature black holes, where are they?

The search for tiny black holes, missing from the Big Bang, may be about to heat up. Just as the trail of such tiny black holes appears to have cooled, an international team of scientists has found clues in quantum physics that could reopen the case. One reason why the hunt for these so-called primordial… Read More »

NASA’s Nancy Grace Roman Telescope will search for tiny black holes left over from the Big Bang

Black hole week is in full swing, and to celebrate, NASA has revealed how its next major astronomy instrument, the Nancy Grace Roman Space Telescope, will hunt for tiny black holes dating back to the Big Bang. When we think of black holes, we tend to imagine huge cosmic monsters, such as stellar-mass black holes… Read More »

Vampire black hole is a ‘cosmic particle accelerator’ that could solve a long-standing astronomy mystery

Scientists may have found evidence that vampire black holes feeding on victim stars called microquasars are cosmic particle accelerators responsible for the mysterious high-energy cosmic rays we see bombarding Earth. These stellar-mass black holes are found in binary systems with a supergiant star from which they greedily rob matter. Some of this stellar material is… Read More »
