US astronomers have found evidence of a star racing tightly around the monstrous black hole at the heart of our galaxy — the closest ever found near the matter-sucking body.
The scientists from the University of California, Los Angeles, said the discovery will help them test Albert Einstein’s theory of general relativity and his predictions of how black holes warp space and time.
The star, S0-102, is orbiting the black hole every 11-and-a-half Earth years, much faster than the 60 years or longer orbit of most of the stars around the Milky Way’s black hole center.
This is only the second star discovered with such a short orbit — the other, S0-2, orbits the black hole every 16 years — thanks to improved imaging techniques.
Lead researcher Andrea Ghez, who has been observing the black hole since she discovered it in 1998, said the second data point is crucial for their research.
“It is the tango of S0-102 and S0-2 that will reveal the true geometry of space and time near a black hole for the first time,” she said in a statement. “This measurement cannot be done with one star alone.”
Like the Earth and other planets, both stars have elliptical orbits — meaning they regularly move closer and further from the black hole.
Ghez and her team at UCLA hope to see evidence of little wobbles in the orbit when the stars move closer, which would show they are being affected by the curvature of space time, as predicted by Einstein’s theory.
Ghez added it was “phenomenal” to find two stars so close to the black hole.
“This should not be a neighborhood where stars feel particularly welcome,” she said.
Black holes, which are what is left when a massive star dies and collapses in on itself, have a gravitational force so strong that even light cannot escape.
They cannot be seen directly, and so are observed through their influence on the things around them.
“Now it’s a whole new ballgame,” Ghez said, adding that the team’s investigations could open a new window into understanding black holes and how the universe evolves.
The research will be published in Friday’s issue of the US journal “Science.”

Trump ridiculed for his late-night ‘OPEN THE SCHOOLS’ rant: ‘Eat your Big Mac and shut up’
President Donald Trump demanded local school boards reopen schools during a late night tweet sent after 11 p.m. on Monday.
"OPEN THE SCHOOLS!!!" Trump demanded, in all capital letters with three exclamation marks.
The president was harshly criticized for his tweet, here's some of what people were saying:
You can't even get your own son's school to open.
They have refused.
The school where your son Barron is being educated refuses to open because it's not safe.
Now sit there, eat your Big Mac, and shut up.
Florida Democrats ask their own candidate to withdraw his candidacy after cocaine arrest: report
Democrats in Florida are asking their own candidate to end his campaign for county commission after an arrest for DUI and cocaine.
"A Collier County commission candidate's arrest in East Naples this past weekend has prompted calls from his party to drop out of the race," the Naples Daily News reported Monday. "John Jenkins, 55, was booked into the Naples Jail Center Sunday morning and faces a felony charge of possession of cocaine, according to a Collier County Sheriff's Office arrest report. He was released later that day on $5,000 bond."
