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;…

Webb telescope observes violence around Milky Way’s central black hole

WASHINGTON: NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive black hole at the centre of our Milky Way galaxy, observing a steady flickering of light punctuated by occasional bright flares as material is drawn inward by its enormous gravitational…

Black holes vibe together in a cosmic love story for Valentine’s Day written in the stars Black Hole

Black holes vibe together in a cosmic love story for Valentine’s Day written in the stars

A simulation of vibing black holes in a cosmic love story. (Image credit: Jamie Lombardi/Allegheny College.) "Roses are red. Violets are blue. Your event horizon means I can't see you!" As that ugly verse shows, black holes aren't exactly conducive to romantic imagery on Valentine's Day. However, a new simulation…

‘We were amazed’: Astronomers discover oldest, biggest black hole jet in the known universe — and there may be more Black Hole

‘We were amazed’: Astronomers discover oldest, biggest black hole jet in the known universe — and there may be more

An artist’s illustration of the gargantuan black hole jets spewing into the early universe. (Image credit: NOIRLab/NSF/AURA/M. Garlick) Astronomers have discovered a black hole jet that erupted into existence when the universe was less than 1.2 billion years old, or roughly 9% its current age. The jet spans 200,000 light-years…

Scientists detect highest-energy ghost particle ever seen — where did it come from? Black Hole

Scientists detect highest-energy ghost particle ever seen — where did it come from?

An illustration shows a high-energy neutrino escaping a supermassive black hole then arriving at Earth after traversing vast cosmic distances. (Image credit: Robert Lea (created with Canva)) Scientists have detected the highest-energy "ghost particle" ever seen. The particle, a type of neutrino, arrived at Earth at nearly the speed of…
