- | President Donald Trump late Thursday threatened a 35% tariff on goods imported from Canada, a dramatic escalation in an on-again, off-again trade war with America’s northern neighbor and one of its most important trading partners. | + | Astronomers discover ‘fossil galaxy’ 3 billion light-years away |

- | And, in a separate NBC News interview, he suggested blanket tariffs on other US trading partners will jump, as well. | + | A galaxy that has remained unchanged for 7 billion years — a rarity in the universe — has been observed by astronomers, offering a glimpse into cosmic history and adding to an enigmatic collection of objects called relics or “fossil galaxies.” |
- | The Thursday actions are the latest examples of a whipsaw policy that’s left investors, trading partners, businesses and everyday Americans alike scrambling to make plans even as the economic ground shifts not just from week to week but in some cases from hour to hour. | + | These space oddities are galaxies that, after an initial phase of intense star formation, escape their expected evolutionary path. While other galaxies expand and merge with one another, the fossil galaxies remain virtually inactive. Like celestial time capsules, they provide a snapshot into the ancient universe and allow astronomers to examine the mechanism of galaxy formation. |
- | It wasn’t immediately clear if the new tariffs, set to take effect August 1, would apply to all Canadian goods or if Trump’s threat applied only to the limited number of goods on which the United States currently levies tariffs. | + | The newly discovered fossil galaxy — named KiDS J0842+0059 — is about 3 billion light-years from Earth, making it both the most distant and the first of its kind observed outside the local universe, the region of space closest to Earth that is approximately 1 billion light-years in radius. It was found by a team of astronomers led by the Italian National Institute for Astrophysics (INAF), using high-resolution imaging from the Large Binocular Telescope in Arizona. |
+ | “Relic galaxies, just by chance, did not merge with any other galaxy, remaining more or less intact through time,” said Crescenzo Tortora, a researcher at INAF and first author of a study on the finding published May 31 in the journal Monthly Notices of the Royal Astronomical Society. “These objects are very rare because, as time goes on, the probability to merge with another galaxy naturally increases.” | ||
- | “Throughout the current trade negotiations with the United States, the Canadian government has steadfastly defended our workers and businesses,” Prime Minister Mark Carney said in a statement to X. | + | Very compact, very massive |
+ | Astronomers believe that the most massive galaxies form in two phases, according to study coauthor Chiara Spiniello, a researcher at the University of Oxford in the UK. | ||
- | “We will continue to do so as we work towards the revised deadline of August 1.” | + | “First, there’s an early burst of star formation, a very quick and violent activity,” she said. “We end up having something very compact and small, the progenitor of this relic.” |

- | Trump’s announcement of higher tariffs on Canada comes amid a flurry of letters Trump has sent to world leaders over the past week informing them what rates their goods will be tariffed at come August 1, absent any trade deals. Trump has sent nearly two dozen such letters. | + | |
- | But Canada is by far the largest trading partner with the United States to receive a letter from Trump this week. Canada and the US have been in trade talks with the hopes of reaching a deal by July 21. | + | The second phase, she added, is a protracted process during which galaxies that are in close proximity start interacting, merging and eating each other, causing a very dramatic change in their shapes, sizes and star populations. “We define a relic as an object that missed almost completely this second phase, having formed at least 75% of its mass in the first phase,” Spiniello explained. |
- | NBC News also reported Thursday that Trump told “Meet the Press” moderator Kristen Welker that the remaining US trading partners that have not yet received trade letters or reached framework agreements will be charged a blanket tariff rate. The United States currently imposes a 10% tariff on nearly all foreign goods coming into the country, but Trump on Thursday said he might double that. | + | The telltale feature of fossil galaxies is that they are very old, compact and dense, much more so than our own galaxy. |
- | “We’re just going to say all of the remaining countries are going to pay, whether it’s 20% or 15%. We’ll work that out now,” Trump said, according to NBC News. | + | “They contain (billions) of stars as massive as the sun and they are not forming any new stars — they’re doing essentially nothing, and they are the fossil records of the very ancient universe,” she said. “They formed when the universe was really, really young. And then, for some reasons that we honestly don’t understand yet, they did not interact. They didn’t merge with other systems. They evolved undisturbed, and they remained as they were.” |
