Prof. Julien de Wit speaks with Dan Rea from WBZ’s Nightside News about his team’s work developing new ways to address threats posted by small asteroids to our critical space infrastructure. “We are developing the technology here at MIT to find [asteroids] and then track them and understand if we should be caring about them,” de Wit explains.
Prof. Julien de Wit, Research Scientist Artem Burdanov and Research Scientist Saverio Cambioni join Edgar Herwick III of GBH’s Curiosity Desk to discuss their work with planetary defense and their method for detecting and tracking smaller asteroids that could impact Earth’s critical space infrastructure. “We are swimming in an era that is data rich, and so what we do in our group and at MIT is mine that data to reveal the universe like never before,” says de Wit. “Revealing new populations of asteroids, new populations of planets, and making sense of our universe like we have never done.”
Using new observations from the James Webb Space Telescope (JWST), astronomers from MIT determined that asteroid 2024 YR4 will not collide with the moon, reports Hannah Devlin for The Guardian. “[Asteroid] 2024 YR4 is exceedingly faint right now, reflecting about as much light as an almond at the distance of the moon,” explain Prof. Julien de Wit and Andy Rivkin PhD '91, who co-led the observations. “Webb is the only observatory that could hope to make these measurements, as it is the only one with the required sensitivity and stability combined with precise moving-target tracking needed to follow and study objects like this.”
Using the James Webb Space Telescope (JWST), astronomers from MIT and other institutions have determined that asteroid 2024 YR4 will not collide with the moon, reports Ashley Strickland for CNN. “Every time we observe an asteroid, we reduce the range of possible trajectories,” explains Prof. Julien de Wit. “In this case, the JWST observations both provided very precise positional measurements and significantly extended the time span over which the asteroid has been observed.”
The American Academy of Sciences & Letters has awarded Prof. Richard Binzel the Barry Prize for his contributions to expanding “humanity’s knowledge of the cosmos,” reports Michael Nietzel for Forbes. The prize is “awarded to scholars at U.S. colleges and universities for distinguished intellectual achievements in the arts, sciences and learned professions,” writes Nietzel.
Prof. Richard Binzel speaks with New Scientist reporter Alex Wilkins about his work inventing the Near-Earth Object Hazard Index (later renamed the Torino scale), asteroid hunting and the future of planetary defense. “Speaking very personally, as a scientist who’s been in the field for 50 years, who has largely been supported by public funds, I feel a moral responsibility to push forward the idea that, because we now have the capability to find any serious asteroid threat, we have a moral obligation to do it,” says Binzel of his work. “Otherwise, we are not doing our job as scientists.”
Prof. Richard Binzel spoke at the Europlanet Science Congress (EPSC) about efforts to create a system that could help deflect deadly asteroids away from Earth, reports Alex Wilkins for New Scientist. “If we had to deal with an actual asteroid threat,” says Binzel, “we would certainly want to know these properties, like the spin or tumbling state [of an asteroid].”
Prof. Julien de Wit speaks with CNN reporter Ashley Strickland about asteroid 2024 YR4 and the importance of monitoring and studying asteroids to help keep Earth safe.
Chronicle visits MIT to learn more about how the Institute “nurtures groundbreaking efforts, reminding us that creativity and science thrive together, inspiring future advancements in engineering, medicine, and beyond.” Prof. Julien de Wit and Research Scientist Artem Burdanov discuss their planetary defense efforts aimed at identifying small asteroids that could pose a threat to Earth, and Prof. Canan Dağdeviren demonstrates her work developing ultrasound devices to detect the earliest stages of breast cancer. Host Anthony Everett notes that: “Big ideas have a way of breaking out of conventional boundaries, just part of what makes MIT one giant laboratory of groundbreaking ideas."
Prof. Richard Binzel speaks with Salon reporter Matthew Rosza about his work creating the Torino Impact Hazard Scale, which measures the threat posed by space rocks. Previous measurements expressed “themselves in different ways, and that could be very confusing to the public,” says Binzel. “This was the motivation for finding a common communication system, a common scale that we could put into context any newly discovered object.”
Prof. Richard Binzel discusses how the risk posed by asteroid 2024 YR4 has now been significantly reduced based off new information gathered on the asteroid’s trajectory, reports Ashley Strickland for CNN. The rapid de-escalation in risk is thanks to the “unsung, meticulous work by astronomers” who conducted a steady stream of follow-up observations of the space rock using telescopes across the globe,” Binzel explains. “I’m pleasantly surprised that we could reduce the probability numbers so quickly.”
Prof. Richard Binzel speaks with Bloomberg reporter F.D. Flam about tracking asteroid 2024 YR4. “It might seem like things are getting more dangerous or more scary, but what's really happening is we're making ourselves more and more secure,” says Binzel.
Prof. Richard Binzel speaks with NBC News reporter Denise Chow about the Torino scale, a method he developed for categorizing the risks posed by near-Earth objects. “The idea was to be as transparent as possible about what astronomers know,” says Binzel of the idea behind the scale.
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."
