You’re probably familiar with black holes. Did you know that millions of black holes could drift around our galaxy like ghosts?
Meanwhile, black holes don’t exist, statistical methods make it possible to identify them. However, black holes that move – the ghostly remains of a collapsed star – are challenging to locate.
Astronomers believe there could be as many as 100M black holes in our galaxy, based on the Milky Way’s 100Billion star count. Some black holes eventually go extinct. Two astronomical research organizations have stated that they used Hubble Space Telescope data in order to find what appears to be a black hole moving through the galaxy.
What triggers a dark hole to form? Supernovae are when stars explode and become black holes. Gravity crushes their cores, creating them. According to NASA’s Hubble Site description, an asymmetrical eruption can send the blackhole “careening throughout our galaxy as a blasted cannonball,” according to the new results.NASA claimed that NASA detected the possibility black hole in the Carina Sagittarius spiral region of our galaxy. This was after telescopes monitoring the brightness of stars picked up anomalies.
Two research teams were based in Baltimore, Maryland at the Space Telescope Science Institute. The University of California at Berkeley hosted the other. They analyzed six years of Hubble telescope data to understand the phenomenon better using a gravitational-microlensing technique.
The surrounding space is warped by a black hole, which amplifies and bends any star’s light. Hubble’s precise recordings were used to help researchers determine the effects of the potential black holes passing in front, measuring how the light from a background Star 19,000 miles away was altered. NASA reported that it helped NASA determine the blackhole’s mass, distance, velocity, and mass.
According to The Space Telescope Science Institute research, the isolated black spot is moving at around 100,000 mph. It can travel faster than 3 hours to get from Earth to Moon.
Hubble’s data covered 270 days where the black hole passed directly in front of the background star. This amplified the star’s light for an additional 270 days. NASA claimed that Hubble showed how the star’s light was rebounded by a millionth of an inch, the same diameter as a Los Angeles 25-cent coin viewed from New York City.
Kailash Sahu of NASA, the Space Telescope Science Institute team leader, stated that measurements were difficult because of another star.
“So it’s similar to trying to measure the tiny movement of a firefly near a bright flashlight,” he explained. “We had a difficult task: subtracting the light from nearby bright stars to measure the faint star’s deflection accurately.
His team projected that the black hole weighed approximately seven of our suns. Sahu confirmed to the USA that their research, which was posted on arXiv, an archive of scientific research, was accepted for publication in The Astrophysical Journal.
But it’s not clear how large or if the black hole is. NASA says that scientists at the California University, Berkeley estimate the object’s mass at between 1.6-4.4 times our sun. Researchers claim that the object could actually contain a neutron star at its lower end.
Science Daily reports that the team’s research was accepted for publication in The Astrophysical Journal Letters.
As black holes, neutrons are also formed after a star falls. These stellar objects don’t go far enough to become black hole-like structures.
“Although it may be an actual black hole, all possibilities must be reported. Jessica Lu, a California University, Berkeley assistant professor of astronomy, said the list includes black holes of lower mass and maybe even a neutron star.
