(CHAPEL HILL, N.C.) — Madyson Barber, a grad student at the University of North Carolina at Chapel Hill, was researching young transiting systems in space when she made a remarkable discovery.
Barber used data from NASA’s Transiting Exoplanet Survey Satellite to observe the brightness of stars over time. During the observations, Barber noticed some “little dips” in brightness, indicating that a “transiting” planet may be passing near Earth.
“This planet discovery popped out,” Barber told ABC News.
The planet, named IRAS 04125+2902 b, is estimated to be 3 million years old, which is considered “young” for stars, Barber said. Earth is about 4.5 billion years old and took an estimated 10 million to 20 millions to form. The next youngest known planet is about 10 million years old, Barber said.
“It’s about the same as a 10-day-old baby in human timescale,” she added. “So, super, super young in comparison to our home.”
Nicknamed “TIDYE-1b” by researchers, the new planet has been shown to have an orbital period of 8.83 days, according to a paper published Thursday in The suspect — who was staying at the Bellevue Men’s Shelter on East 30th Street — was apprehended around East 46th Street and First Avenue, police said.
He appeared to pick the victims at random, police said.
“He just walked up to them and began to attack them,” Chief of Detectives Joe Kenny said at a news conference.
Two bloody kitchen knives were recovered, police said.
Rivera has eight prior arrests in New York City, according to law enforcement, and is believed to have severe mental health challenges, Mayor Eric Adams said. Rivera’s case renewed frustration with the city’s inability to treat people in mental distress and hold people with a history of low-level criminal activity.
“There’s a real question as to why he was on the street,” Adams said.
Rivera’s prior arrests mainly involved shoplifting, officials said. None involved a weapon.
He was out without bail pending trial on his most recent arrests.
He had two documented interactions with the city while in mental distress.
