In January, researchers at the University of California, Los Angeles unveiled an artificial 'mini sun' that can generate sound waves to mimic the effects of gravity. Scientists have also used lab equipment to copy other cosmic entities, such as the sun.

Their results revealed that black holes likely produce Hawking radiation, a faint glow of radiation from virtual particles that randomly pop into existence near the black hole boundaries - a phenomenon first predicted by Stephen Hawking. Astronomers have a new, more complete picture of the supermassive black hole at the center of a galaxy 55 million light-years from Earth the first black hole ever to be imaged. In November 2022, researchers also used a single-file chain of atoms to simulate the event horizon of a black hole. Object mistaken as a galaxy is actually a black hole pointed directly at Earth The most elusive black holes in the universe could lurk at the Milky Way's center Behold the first direct image of a supermassive black hole spewing a jet of particles But because the metallic fluid is contained within a pipe rather than forming naturally, researchers can learn a limited amount via this method. In the past, researchers have tried to recreate accretion disks by pumping liquid metals through circular pipes at high speeds to mimic the properties of plasma. This is not the first time that scientists have attempted to study back holes in the lab. This animation shows the side view of a black hole's accretion disk, which seems to bend above, below and around the hole at the same time.

The entire system would have around 1 million times the Sun’s mass. A distinctive feature called a photon ring outlines the black holes. The results were published May 12 in the journal Physical Review Letters. The simulation shows how the black holes distort the starry background and capture light, producing black hole silhouettes. But the researchers hope that they will be able to extend the duration of the pulses, allowing them to see how the disks grow over multiple rotations.

The rotating masses lasted for only one full rotation, which takes around 150 nanoseconds (150 billionths of a second) to complete. MAGPIE created the artificial rings by accelerating eight separate plasma jets and colliding them to form a central spinning column, within which plasma nearer the center rotated faster than plasma toward its edge, just like in an accretion disk, the researchers wrote in a statement.

But now, researchers at Imperial College London have recreated one using the university's Mega Ampere Generator for Plasma Implosion Experiments (MAGPIE) machine. Astronomers have found a very tiny region jam-packed with the mass of 800 suns that is creating chaos among nearby stars, all of which points toward an intermediate-mass. The only direct observation of an accretion disk is the blurred halo of orange light photographed around M87*, a solar system-size black hole at the heart of the galaxy Messier 87. A rare midsize black hole may be lurking at the center of a star party just 6,000 light-years away.
