Prof. Richard Binzel goes interstellar and chats with Boston Globe reporter Nick Stoico about the science behind the meteor that exploded over Cape Cod Bay recently, noting that the event offered a rare opportunity for people to connect with a phenomenon that usually goes unnoticed. “It’s great when people find a connection to the greater universe,” said Binzel. “It’s a great perspective to think beyond the surface of the Earth.”
MIT engineers have developed a “two-in-one propulsion system that can fuel both traditional chemical thrusters and electrical thrusters, combining speed and power with slower, more precise maneuverability for small satellites,” reports Passant Rabie for Gizmodo. “The new propulsion system would allow small satellites to carry both thrusters using the same propellant, opening the door for cheaper, smaller spacecraft to explore beyond Earth orbit,” Rabie explains.
Prof. Richard Binzel shares his insights into the recently discovered school-bus sized asteroid that will fly by Earth next week with CNN reporter Jacopo Prisco. “2026JH2 will pass safely by the Earth,” said Binzel. “This is actually a rather normal occurrence, car-sized objects pass between the Earth and the Moon every week. At the size of a school bus, these pass through our neighborhood several times per year. We are only recently developing surveys that are sensitive enough to see them.”
Researchers from MIT have created a new model that can predict wave behavior on different planets, reports Kristen French for Nautilus. “On Earth, waves form as wind drags across bodies of water, pushing unevenly on their surfaces. As the waves lengthen, and the distance between crests grows, the waves are increasingly driven by the force of gravity rather than by surface tension,” French writes. “On faraway planets, the size of the waves would depend not only on the strength of gravity and the speed and direction of the wind, but the density of the atmosphere, the viscosity of the liquid in the oceans and lakes, as well as the depth of the bed. All these factors were fed into the PlanetWaves model.”
MIT scientists have developed a new model, dubbed "PlanetWaves," that predicts wave behavior on different planets, showing that the "smallest gust of wind on Titan could generate huge, roiling waves across seas of hydrocarbons," reports Andrew Paul for Popular Science. “PlanetWaves is far more than a novel simulator,” writes Paul. “Calculating fluid behaviors on distant planets and moons could help inform engineers building new spacecraft and probes.”
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.”
Prof. Richard Teague speaks with CNN reporter Asuka Koda about how an international team of astronomers have “captured the most complete, high-resolution map of the cold gas at the center of the Milky Way, which contains the raw material from which stars and planets are made” using the Atacama Large Millimeter/submillimeter Array, or ALMA. “I think astronomy on this scale is really no longer about small individual people pushing in their labs, but about huge international collaborations,” says Teague. “And I think that’s what’s particularly impressive about this piece of work, just the scale of that collaboration that you need to make it happen.”
A study by researchers at MIT has found that high levels of greenhouse gas emissions in the atmosphere is impacting the satellite orbits that typically force objects back to Earth, leading to an increased amount of space junk, reports Sachi Kitajima Mulkey for The New York Times. “[W]e’re losing this cleaning force that we rely on” says William Parker PhD '25.
Quanta Magazine reporter Jonathan O’Callaghan spotlights Prof. David Kaiser and graduate student Alexandra Klipfel, and their work searching for evidence of primordial black holes. “Very little mass gets radiated over the majority of the black hole’s lifetime,” explains Klipfel. “But then, right at the end, it emits a majority of its mass in a very rapid explosion. It heats up really, really quickly, a runaway process that ends in a big explosion of ultra-high-energy particles.”
The Economist chronicles the life and work of Prof. Nuno Loureiro, from his childhood in Portugal where he dreamed of becoming a scientist to his work at MIT as a “fusion pioneer” leading the Plasma Science and Fusion Center. “He walked into his classes beaming, ready to cover the blackboard with figures. He joked like a friend, but he worked his students vigorously, advising them that if they were not yet the best, they should strive to be. Failure was not to be feared, because it showed they were trying to tackle the really hard problems.”
Prof. Nuno F.G. Loureiro is remembered as a “brilliant ‘physicist’s physicist,’” who “pushed for revolutionary breakthroughs in the complex, arcane field of plasma science,” in a tribute by Boston Globe reporter Brian MacQuarrie. “Inside and outside the lab, Mr. Loureiro also was known for a charismatic leadership style that combined warmth, humor, and personal engagement in the relentless pursuit of excellence,” MacQuarrie writes. “Nuno represents what MIT treasures in its people,” notes Prof. Joseph Paradiso, “at the top of his game in research, but with a wide-ranging curious mind ready to grapple with new ideas.”
In honor of the 25th anniversary of the International Space Station (ISS), Earth.com reporter Derek Davis spotlights the contributions of a number of MIT-trained astronauts and engineers, who played pivotal roles in the ISS’ history.
