Popular Science’s Andrew Paul spotlights how MIT astronomers have identified a black hole star (MoM-BH*-1), a gigantic, dense gas cloud fueled by a central black hole, discovered in an image of a large red dot on NASA’s James Webb Space Telescope (JWST). “The groundbreaking realization and newest addition to the cosmic catalogue wouldn’t have been possible without the JWST, whose smallest discoveries have massive ramifications,” writes Paul. “Even something as tiny as a 100-million-year-old red dot.” 

Using NASA’s James Webb Space Telescope (JWST), MIT researchers have discovered a black hole star, MoM-BH*‑1, the earliest example of a black hole in the universe, writes Mashable’s Elisha Sauers. “We argue that Black Hole Stars may be powering all of JWST's Little Red Dots that are found almost everywhere in the early Universe,” says Postdoctoral Associate Rohan Naidu. “Which is to say, this channel of making massive black holes must be very common, to the point where every massive black hole (like the Milky Way's) may have gone through this phase.” 

Postdoctoral Associate Rohan Naidu speaks to The Guardian’s Ian Sample about his team’s research discovering a black hole star, a cosmic object the size of the entire solar system. “They [black hole stars] may govern when stars are able to form and when they cease forming, setting the course for everything that follows from star formation: the birth of planets, the rise of life, the emergence of species that may one day piece together this entire history,” says Naidu.  

MIT researchers have discovered space matter that has been ‘missing’ since the 1990s using Fast Radio Bursts, individual flashes of radio waves traveling through space and coming from the distant universe, reports WCVB 5’s Cindy Fitzgibbon. “The takeaway of the study is that by discovering the distribution of the missing matter around galaxies, we have found evidence for strong activities in galaxies,” says graduate student Haochen Wang, a co-author on the study. “In other words, galaxies are busier and messier than we thought.” 

By studying ‘smears’ in fast radio bursts, fleeting flashes of radiation, MIT researchers discovered diffuse clouds of baryonic gas may contain the missing ordinary matter in the universe, writes Gizmodo’s Gayoung Lee. “These diffuse clouds may be flung outside galaxies through black hole jets,” Lee explains. 

Prof. Paul Lozano and alumna Amelia Bruno PhD ‘25 join John Batchelor, host of the "Hotel Mars” podcast, to discuss their work developing a new propulsion system that could improve small satellite mobility. “This technology [electrospray thrusters] came from our own research on how to miniaturize propulsion for small satellites,” says Lozano. “There is a big need to actually provide these little satellites with mobility, so that we can actually explore space and use it more effectively.” 

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.”
