A huge black hole is tearing through space, leaving behind a 200,000-light-year-long trail of newborn stars, scientists say.
The supermassive monster — likely born of a bizarre game of intergalactic billiards — is rampaging through the blackness and plowing into gas clouds in its path.
The incredible forces at play mean this gas is being forged into a contrail of new stars, which have been captured on camera by NASA’s Hubble Space Telescope.

“We think we’re seeing a wake behind the black hole where the gas cools and is able to form stars,” Yale University astronomer Pieter van Dokkum said.
“What we’re seeing is the aftermath. Like the wake behind a ship, we’re seeing the wake behind the black hole,” he said.
Researchers say that gas is probably being blasted and warmed by the motion of the black hole.
“Gas in front of it gets shocked because of this supersonic, very high-velocity impact of the black hole moving through the gas,” Van Dokkum said.
The black hole weighs about the same as 20 million of our suns.
Scientists say it began its rampage after being ejected from a celestial menage a trois.
The working theory is that two galaxies probably merged about 50 million years earlier, bringing together two supermassive black holes, which whirled around each other harmoniously.
A third galaxy butted in with its own black hole, creating an unstable and chaotic scene that eventually saw one of them ejected at high speed — fast enough to travel between the Earth and the moon in just 14 minutes.
Stargazers say there is no cause for earthly concern because this is all far away.
It is also a long time ago — back when the universe was half of its current age. It is visible now because of the time it has taken for light to arrive here.
The runaway black hole, which has never been seen before, was discovered by accident, Van Dokkum said.
“I was just scanning through the Hubble image and then I noticed that we have a little streak,” he said.
“It didn’t look like anything we’ve seen before,” he said, adding that the star trail is “quite astonishing, very, very bright and very unusual.”
While this is the first tearaway black hole ever spotted, it might not be the only one, NASA said.
The Nancy Grace Roman Space Telescope, which is expected to launch some time this decade, should give astronomers a much wider view of the universe — and could lead to the discovery of more of these star-forming runaways.
‘TERRORIST ATTACK’: The convoy of Brigadier General Hamdi Shukri resulted in the ‘martyrdom of five of our armed forces,’ the Presidential Leadership Council said A blast targeting the convoy of a Saudi Arabian-backed armed group killed five in Yemen’s southern city of Aden and injured the commander of the government-allied unit, officials said on Wednesday. “The treacherous terrorist attack targeting the convoy of Brigadier General Hamdi Shukri, commander of the Second Giants Brigade, resulted in the martyrdom of five of our armed forces heroes and the injury of three others,” Yemen’s Saudi Arabia-backed Presidential Leadership Council said in a statement published by Yemeni news agency Saba. A security source told reporters that a car bomb on the side of the road in the Ja’awla area in
PRECARIOUS RELATIONS: Commentators in Saudi Arabia accuse the UAE of growing too bold, backing forces at odds with Saudi interests in various conflicts A Saudi Arabian media campaign targeting the United Arab Emirates (UAE) has deepened the Gulf’s worst row in years, stoking fears of a damaging fall-out in the financial heart of the Middle East. Fiery accusations of rights abuses and betrayal have circulated for weeks in state-run and social media after a brief conflict in Yemen, where Saudi airstrikes quelled an offensive by UAE-backed separatists. The United Arab Emirates is “investing in chaos and supporting secessionists” from Libya to Yemen and the Horn of Africa, Saudi Arabia’s al-Ekhbariya TV charged in a report this week. Such invective has been unheard of
US President Donald Trump on Saturday warned Canada that if it concludes a trade deal with China, he would impose a 100 percent tariff on all goods coming over the border. Relations between the US and its northern neighbor have been rocky since Trump returned to the White House a year ago, with spats over trade and Canadian Prime Minister Mark Carney decrying a “rupture” in the US-led global order. During a visit to Beijing earlier this month, Carney hailed a “new strategic partnership” with China that resulted in a “preliminary, but landmark trade agreement” to reduce tariffs — but
SCAM CLAMPDOWN: About 130 South Korean scam suspects have been sent home since October last year, and 60 more are still waiting for repatriation Dozens of South Koreans allegedly involved in online scams in Cambodia were yesterday returned to South Korea to face investigations in what was the largest group repatriation of Korean criminal suspects from abroad. The 73 South Korean suspects allegedly scammed fellow Koreans out of 48.6 billion won (US$33 million), South Korea said. Upon arrival in South Korea’s Incheon International Airport aboard a chartered plane, the suspects — 65 men and eight women — were sent to police stations. Local TV footage showed the suspects, in handcuffs and wearing masks, being escorted by police officers and boarding buses. They were among about 260 South
