Using the James Webb Space Telescope (JWST), astronomers have found the most distant merger between supermassive black holes ever detected. Colliding black holes are at the heart of merging galaxies so distant that the collision appears to have occurred just 740 million years after the Big Bang, when the 13.8 billion-year-old universe was a fraction… Read More »
Black hole week ends today (May 10), and there’s no better way to mark the occasion than with “egg-casual” black hole science. Using gravitational wave measurements made by the US-based Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo and KAGRA detectors in Italy and Japan, scientists found that the orbits of some binary black… Read More »
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 »
Black holes have long attracted attention as celestial bodies from which nothing, not even light, can escape. However, theoretical physicists propose a less understood but equally fascinating counterpart: white hole. Unlike black holes that attracted matter, white holes repelled it. What are White Holes? In astrophysics, a white hole represents a theoretical phenomenon in which… Read More »
The James Webb Space Telescope (JWST) observed light from stars surrounding some of the universe’s ancient supermassive black holes; black holes appeared less than a billion years after the Big Bang. The observations, carried out by a team from the Massachusetts Institute of Technology (MIT), address the question of how these cosmic giants at the… Read More »
In 2015, the iconic Laser Interferometer Gravitational Wave Observatory (LIGO) made the first concrete detection of gravitational waves. The waves were the result of the collision of two black holes far away in the universe; Since then, numerous such signals have been detected from mergers of black holes, neutron stars, and even a few mixed… Read More »
Scientists may be one step closer to discovering how gamma-ray bursts became some of the most powerful explosions in the known universe. For context, a single gamma-ray burst, or GRB, can produce more energy in seconds than the sun will radiate in billions of years. Because of this power, scientists suggest that GRBs are created… Read More »
About a trillion tiny particles called neutrinos pass through you every second. These “remnant” neutrinos created during the Big Bang exist throughout the universe, but they can’t harm you. In fact, in your entire life, only one of them is likely to touch an atom in your body. Most neutrinos produced by objects such as… Read More »
