Gaia BH1 (Gaia DR3 4373465352415301632) is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus. [4]
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
Getting the black hole to act as a power source and engine also requires a way to convert the Hawking radiation into energy and thrust. One potential method involves placing the hole at the focal point of a parabolic reflector attached to the ship, creating forward thrust, if such a reflector can be built.
The famous first picture of the supermassive black hole at the heart of our galaxy might not be accurate, a new study has claimed. The picture – initially published in 2022, after years of ...
Dr George Seabroke, Mullard Space Science Laboratory at UCL, a member of Gaia’s black hole task force, the team that made the discovery, said: “Finding Gaia BH3 is like the moment in the film ...
The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon.
The black hole and star orbit the system barycentre every 11.6 years, with an orbital distance ranging from 4.5–29 AU. [3] The black hole's mass is 32.70 M ☉, the heaviest known stellar black hole in the Milky Way. The black hole Gaia BH3 is the second known stellar black hole more massive than about 10 M ☉ (with the first being Cygnus X ...
The images show the Perseus Cluster and the Centaurus Cluster, each with a central black hole appearing as a bright white dot surrounded by patches and filaments of gas.
