Black Hole

Back in 1971, a couple of British astronomers predicted the existence of a black hole at the center of our galaxy. And in 1974, other astronomers found it, naming it Sagittarius A*. Since then, astronomers have discovered that a similar “supermassive black hole” sits at the center of almost every…

An illustration shows a rotating supermassive black hole. (Image credit: Robert Lea (created with Canva)) Scientists have discovered that some supermassive black holes rotate much more rapidly than expected. The discovery came as the result of a new form of "black hole archeology" that links black hole spins to the…

Dark matter drives galaxy formation within the ΛCDM framework, with massive dark matter halos forming in the early Universe. Studying dark matter from the first billion years is crucial. Galaxies form within dark matter halos and grow by accreting gas, with baryon movements shaping them and their halos. An international…

Home » Science » Candidate Dyson Sphere Detections Are Regular Stars with Black Hole Galaxy Behind Astronomers looked more closely at one of seven stars that looked like possible Dyson sphere candidates from earlier observations. They used high-resolution e-MERLIN and EVN (e-VLBI) observations of a radio source associated with Dyson…

An illustration shows a black hole merger and its mirror image. (Image credit: Robert Lea (created with Canva)) By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, scientists could reveal hidden asymmetries in the universe. The team behind new research on the topic…

Astronomers have detected the largest black hole-launched jet ever seen in the early universe. The twin-lobed jet that existed when the universe was just 1.2 billion years old stretches out for an incredible 200,000 light-years at the very least, making it twice as long as the width of the Milky…

Astronomers have spotted a massive radio jet in the early universe, which they say is the largest known from that era. The jet is at least 200,000 light-years long, making it twice the width of the Milky Way. It formed when the universe was less than 10% its current age…

An illustration shows the Einstein Probe and two possible explanations for a powerful cosmic explosion it witnessed (Image credit: Robert Lea (Created with Canva)) Astronomers are trying to understand a mysterious cosmic explosion that the Einstein Probe spacecraft spotted in April last year. The highly energetic explosion was initially attributed…
