The is The closest black hole to Earth It is detected, although you can rest easy because it is inactive.
Gaia BH1 is 1,600 light-years away, which is three times closer than the last record-breaking black hole in the constellation Ophiuchus. The black hole weighs ten times the mass of our sun.
Paper published in the monthly notifications for Royal Astronomical Society Last week, details of the discovery of a “sun-like star orbiting a dark body”.
The team of researchers initially identified the black hole using the European Space Agency’s Gaia spacecraft, according to a press release from the Harvard-Smithsonian Center for Astrophysics.
The researchers then made 39 additional observations using six different telescopes around the world over a four-month period.
Using a telescope in Hawaii he manages NOIRLab of the National Science Foundationthe team was able to confirm that the central “dark body” was an inactive black hole.
Does this discovery pose any problems?
“Take the solar system, put a black hole where the sun is, and the sun where the earth is, and you get that system,” he said. Karim Al-Badrilead author of the paper and an astrophysicist at the Harvard-Smithsonian Center for Astrophysics and the Max Planck Institute for Astronomy.
“Although there have been many discoveries of systems like this, almost all of these discoveries have been refuted later.
“This is the first unequivocal discovery of a Sun-like star in a wide orbit around a stellar-mass black hole in our galaxy.”
Astronomers estimate that there are 100 million black holes in our galaxy, but very few have been confirmed so far.
The Harvard-Smithsonian Center for Astrophysics He notes that almost all black holes that have been confirmed are “active”.
Scientists can tell whether a black hole is active or inactive with X-ray radiation.
Active black holes glow when they attract surrounding material into space. Inert black holes do not emit high levels of X-rays, which makes them more difficult to see.
If a black hole is not actively feeding, that is, inactive, then it simply merges with its surroundings.
This is what a black hole looks like
This summer, NASA scientists revealed what a black hole might look like using sonication.
A supermassive black hole is located at the center of the Perseus cluster of galaxies, approximately 55 million light-years away, and has been used as a study.
A black hole was first associated with sound in 2003, when astronomers discovered that pressure from the hole caused ripples in the cluster’s hot gas.
The sound was thought to be about 57 octaves below the middle “C”, making it inaudible to human ears.
However, by using sonication, “translating astronomical data into sound,” the astronomers altered the pitch of the sound from 57 to 58 octaves above the estimated pitch so that the sound of the crater could be heard by humans.
Using sound waves first recorded by the Chandra X-ray Observatory, scientists took radial sound waves and recombined them to make them audible.
The sounds of the new black hole contradict the popular notion that there is no sound in space.
In addition to the supermassive black hole at the center of the Perseus cluster of galaxies, astronomers have also imaged a black hole at the center of galaxy M87, which is famous as the first black hole ever photographed.
