Prof. Richard Binzel speaks with Forbes reporter Jamie Carter about how astronomers are working to determine the trajectory of asteroid 2024 YR4. “Eventually, we expect the probability to fall to zero and reach Torino Scale 0 (all clear!),” says Binzel. “The uncertainty region, which looks like a long spaghetti of fettuccine string, shrinks as we get tracking data over a longer and longer piece of the asteroid’s orbit.”
Prof. Richard Binzel, creator of the Torino scale that NASA uses to measure the threat of incoming objects, speaks with Brandon Truitt of CBS Boston about his quest to track 2024 YR4, an asteroid that astronomers are closely monitoring to see how close it might come to Earth in 2032. “As we get more and more measurements, we keep tracking the asteroid, that uncertainty window, that broad range of where it could go it's going to shrink and shrink," says Binzel. "Until the Earth falls outside of that pathway, we're going to see these probabilities bounce around."
Prof. Richard Binzel speaks with CNN reporter Ashley Strickland about the trajectory of asteroid 2024 YR4. “YR4 presents a challenge because it is small and headed away. Telescopes on the ground can track it for a few more months. Then we’ll call (the James Webb Space Telescope) into service to track it even further, if needed,” says Binzel. “While certainty for 2024 YR4 missing the Earth is the outcome we expect, it’s not up to us. It’s for nature to decided. In fact, nature already has settled the question. We just don’t know that answer yet. That’s why our tracking efforts continue.”
Prof. Richard Binzel, Prof. Julien de Wit, and Research Scientist Artem Burdanov speak with NBC 10 Boston reporter Matt Fortin about their new asteroid-detecting method that will be used to track the newly discovered asteroid 2024 YR4 and help protect Earth. “By refining and applying their technique, my colleagues [de Wit and Burdanov] have basically turned the JWST into the most capable asteroid-tracking system in history,” explains Binzel.
In an interview with NBC News reporter Kathy Park, Prof. Richard Binzel, Prof. Julien de Wit, and Research Scientist Artem Burdanov provide insight into astronomer's efforts to learn more about asteroid 2024 YR4. “This is an object that merits tracking by astronomers, merits our attention and that’s simply what we are doing,” says Binzel.
Profs. Richard Binzel, Julien de Wit and Research Scientist Artem Burdanov speak with Boston Globe reporter Sarah Mesdjian about asteroid 2024 YR4 and their work developing a new method to “find and track far-away asteroids that were previously undetectable by using technology they compared to long-exposure images.” Says Binzel: “With improving technology, we are going to be aware of more and more of these objects.” He adds: “It’s a really important learning process what we’re doing right now. So when we find more and more of them, we know how to quickly process them and assess which of them are really worth looking further into.”
Research Scientist Artem Burdanov speaks with Boston.com reporter Molly Farrar about asteroid 2024 YR4. Burdanov and his colleagues recently developed a new detection method that could be used to track potential asteroid impactors and help protect our planet. “We need to observe it more, and then we can make an informed decision,” says Burdanov, “but it’s good that we have telescopes and scientists who can do this type of work and inform the public about the threat.”
Research Scientist Artem Burdanov speaks with WBZ News Radio reporter Chaiel Schaffel about his team’s work developing a new detection method that could be used to track potential asteroid impactors like 2024 YR4 and help protect our planet. Burdanov and his colleagues used the new method to detect “138 asteroids ranging in size from a bus to the size of Gillette Stadium.” Burdanov explains that he and his colleagues "used a clever technique to find asteroids that are hidden in the noise.”
Prof. Julien de Wit speaks with National Geographic reporter Robin George Andrews about how special infrared filters on the James Webb Space Telescope (JWST) can be used to find small asteroids and precisely determine their size. “Asteroids get much brighter in the infrared than in the visible as they move away from Earth, and they are thus easier to detect or track with infrared facilities—JWST being the biggest of all,” says de Wit.
MIT astronomers have analyzed the scintillation – or glistening - produced by a fast radio burst (FRB) to help identify the location of the pulses, reports Ashley Strickland for CNN. “We discovered that this FRB exhibits ‘twinkling,’ similar to how stars appear to twinkle in the night sky,” explains postdoc Kenzie Nimmo. “Observing this scintillation indicates that the region where the FRB originated must be incredibly small.”
Graduate student Palak Patel speaks with BBC News reporter Chris Baraniuk about her work designing an “experimental molten regolith electrolysis system, for extracting oxygen and metal from the lunar soil.” Palak explains: “We’re really looking at it from the standpoint of, ‘Let’s try to minimize the number of resupply missions.’”
USA Today reporter Eric Lagatta writes that a new study by MIT researchers finds that X-ray flashes emanating from a supermassive black hole located 270 million light-years from the Milky Way could be caused by a dead stellar remnant, or white dwarf. The researchers believe that the white dwarf could be “spinning precariously on the edge of the black hole, causing the explosions of high-energy light.”
MIT astronomers have detected X-ray flashes erupting from a supermassive black hole that seem to be caused by a nearby white dwarf, reports Will Dunham for Reuters. “It is probably the closest object we've ever observed orbiting around a supermassive black hole,” says graduate student Megan Masterson. “This is extremely close to the black hole's event horizon.”
MIT astronomers have witnessed flashes of X-rays shooting out of a black hole and believe that a dead star, or white dwarf, passing close by the black hole could be causing the eruptions, reports Mark Kaufman for Mashable. “The astronomers ran simulations of what could drive these unusual bursts of energy,” writes Kaufman. “The most plausible outcome is this brazen white dwarf (the spent core of a sun-like star), which is about one-tenth the mass of our sun. It's shedding its dense, outer layer and triggering these pulses of X-rays.”
Space.com reporter Robert Lea writes that using the XMM-Newton X-ray telescope, MIT astronomers have observed bursts of X-rays erupting with increasing frequency from a supermassive black hole, a behavior they think could be caused by a “dead stellar core, or white dwarf, daringly teetering on the edge of the black hole.” Lea explains that “if the source of these strange episodes is a finely balanced white dwarf, the researchers theorize that it could be detected using ripples in space and time called gravitational waves emitted from the system.”
