Webb telescope finds Milky Way black hole never stops strobing light

These flares are bright enough to shine across 26,000 light-years of space. By Elisha Sauers Elisha Sauers writes about space for Mashable, taking deep dives into NASA's moon and Mars missions, chatting up astronauts and history-making discoverers, and jetting above the clouds. Through 17 years of reporting, she's covered a…

How do black holes ‘leak’ energy? Scientists have a new spin on the answer Black Hole

How do black holes ‘leak’ energy? Scientists have a new spin on the answer

An illustration shows a spinning black hole (Image credit: Robert Lea (created with Canva)) Black holes may leak more energy to their surroundings than previously suspected — and the faster these voids spin, the more efficient this energy extraction seems to be. With this in mind, a team of scientists…

Why are ‘fireworks’ coming from a black hole? This is what scientists say

This artist's concept shows Sagittarius A*, a supermassive black hole at the center of the Milky Way galaxy, surrounded by a swirling accretion disk of hot gas. Flaring hot spots that resemble solar flares are seen in the disk. NASA, ESA, CSA, Ralf Crawford (STScI)/NASA.gov hide caption toggle caption NASA,…

Scientists may have just discovered 300 of the rarest black holes in the universe

An artist's illustration of three black holes. (Image credit: Shutterstock) Astronomers have used the Dark Energy Spectroscopic Instrument (DESI) to discover a treasure trove of black holes, many of which are rare "missing links" in the cosmic monsters' evolution. The search, which swept across 410,000 galaxies, identified a staggering 2,500…

2,500 New Active Black Holes Identified, Raising Questions About How They Evolve Black Hole

2,500 New Active Black Holes Identified, Raising Questions About How They Evolve

Scientists using the Dark Energy Spectroscopic Instrument (DESI) have completed two major tasks. They’ve compiled the largest ever sample of dwarf galaxies (systems contain up to a mere several billion stars, compared to the Milky Way’s estimated 2 billion to 400 billion) that host an actively feeding black hole. They’ve…

Milky Way’s Supermassive Black Hole is More Active than Previously Thought Black Hole

Milky Way’s Supermassive Black Hole is More Active than Previously Thought

The accretion disk orbiting Sagittarius A* is emitting a constant stream of flares with no periods of rest, according to an analysis of new data from the NASA/ESA/CSA James Webb Space Telescope; while some flares are faint flickers, lasting mere seconds, other flares are blindingly bright eruptions, which spew daily;…
