Black Hole

By combining data from NASA’s IRAS and NuSTAR telescopes, scientists have uncovered more hidden supermassive black holes than earlier estimates suggested. Their findings indicate that over a third of these black holes are obscured by thick gas and dust, influencing how galaxies grow and evolve. The study demonstrates the power…

A child can have their father's eyes, their mother's smile, or maybe even their grandfather's…

New data from NASA’s Chandra X-ray Observatory and ESO’s Very Large Telescope provide evidence that outbursts from supermassive black holes can help cool down gas to feed themselves. These images show two of the galaxy clusters in the study, the Perseus Cluster and the Centaurus Cluster. Chandra data represented in…

These eerie wails are a real sound wave from a supermassive black hole NASA created a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away. The black hole is at the center of the Perseus cluster of galaxies, and the acoustic…

An illustration shows seven "little red dot" galaxies embedded in the cosmic web, one of which is dominated by a supermassive black hole (Image credit: Robert Lea (created with Canva)) Using the James Webb Space Telescope (JWST), astronomers have discovered distant, overly massive supermassive black holes in the early universe.…

Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves.…

(Image credit: © CfA/Mel Weiss) The James Webb Space Telescope (JWST) has detected a flare from the supermassive black hole at the center of the Milky Way — and it could help explain why these strange outbursts occur.. Sagittarius A* is 4 million times the mass of the sun and…
