Discovery of “tipped over” black hole surprises NASA scientists
NASA researchers combined years of data and new imaging techniques to learn more about a “tipped over” black hole that is moving in an unexpected way.
The black hole is located in a galaxy called NGC 5084. Researchers have been aware of the galaxy for years, NASA said in a news release.
New analysis techniques developed at NASA’s Ames Research Center in California helped researchers see four long plumes of plasma emanating from the galaxy. Most galaxies don’t have plumes, and when they do, only one or two are present. The plumes suggested the galaxy might house a supermassive black hole, NASA said. Spotting both pairs, which formed an “X” shape, led researchers to focus more on the area.
Using archived data from NASA’s Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array Telescope based in Chile, researchers found that the galaxy also had a “small, dusty inner disk” rotating at the center of the galaxy, again suggesting a black hole there. Even more surprisingly, both the disk and black hole were rotating at a 90-degree angle relative to the rest of the galaxy, meaning both features are essentially “lying on their sides,” NASA said.
“It was like seeing a crime scene with multiple types of light,” said research scientist Alejandro Serrano Borlaff, who will also publish a paper about the discovery, in the news release. “Putting all the pictures together revealed that NGC 5084 has changed a lot in its recent past.”
It’s not clear what caused the change in the galaxy. It may have collided with another galaxy and formed a chimney of superheated gas, creating the X-shaped plasma plumes. Further research will have to be conducted to learn more about the circumstances.
“Detecting two pairs of X-ray plumes in one galaxy is exceptional,” said Pamela Marcum, an astrophysicist at Ames and co-author on the discovery, in the news release. “The combination of their unusual, cross-shaped structure and the ‘tipped-over,’ dusty disk gives us unique insights into this galaxy’s history.”

Trump shakes up spending talks with call on Congress to eliminate debt ceiling
In a move that has stunned Washington, President-elect Donald Trump is now urging Congress to eliminate the debt ceiling, dramatically shaking up talks among lawmakers, who are at an impasse over federal spending and government funding, which is scheduled to lapse this weekend.
While some on Capitol Hill have balked at Trump’s latest demand, the president-elect was unwavering on Thursday. He said he is determined to hold his position that lawmakers should both oppose any sweeping spending measure that includes “traps” from Democrats and abolish the debt limit before he takes office next year.
“Number one, the debt ceiling should be thrown out entirely,” Trump said in a phone interview. “Number two, a lot of the different things they thought they’d receive [in a recently proposed spending deal] are now going to be thrown out, 100%. And we’ll see what happens. We’ll see whether or not we have a closure during the Biden administration. But if it’s going to take place, it’s going to take place during Biden, not during Trump.”
Trump’s comments, which have sent negotiators in both parties back to the drawing board ahead of the expiration of government funding at 12:01 a.m. on Saturday, came a day after he called a bipartisan spending deal “ridiculous and extraordinarily expensive” and said that any legislation to extend the federal government’s funding should also include plans for “terminating or extending” the debt limit.
Still, Trump, who built a decades-long business career as a negotiator and dealmaker, appeared to leave room for House Speaker Mike Johnson and other top Republicans to find consensus on new options that he would find sufficient.
When asked how he would like to see this standoff end, Trump replied, “It’s going to end in a number of ways that would be very good.”
Trump said the discussions are ongoing and it is too soon for him to spell out more details on what the contours of a final agreement should be.
“We’ll see,” Trump said. “It’s too early.”
But Trump said he will continue to closely track how Democrats might seek to influence any revised deal and voiced displeasure at how the initial bipartisan deal had Democratic provisions.
“We caught them trying to lay traps. And I wasn’t going to stand for it,” he said. “There are not going to be any traps by the radical left, crazy Democrats.”
Tesla CEO Elon Musk, a billionaire who spent almost $300 million to back Trump and other Republican candidates in the November elections, also opposed the initial bipartisan spending deal, which he called “terrible.” When Johnson scrapped it, Musk wrote on X, “The voice of the people has triumphed!”
Trump’s focus on the debt ceiling, which caps the federal government’s borrowing authority, comes as he faces a showdown over the issue during the first year of his upcoming term. That prospect, several people close to Trump say, has drawn his attention because he wants to spend his time and political capital next year on other issues and would prefer Congress addresses it now.
While the current cap on federal borrowing is suspended until Jan. 1, 2025, the Treasury Department would be able to take steps to avoid default for a few months into next year. Nevertheless, the government could face an economically fraught default sometime early next year should the debt ceiling not be extended or addressed by Congress.
When asked Thursday about Trump’s call to address the debt limit, Rep. Hakeem Jeffries of New York, the House Democratic leader, said, “the debt-limit issue and discussion is premature at best.”
