Prof. Brett McGuire joins Peter O'Dowd, host of WBUR’s “Here & Now,” to discuss astronomers’ discovery of Erythrulose, the sugar found in raspberries, in clouds of gas about 25,000 light-years away from Earth. “By a chemist's formal definition this is a sugar—given its structure, the way its atoms are bonded together. It’s not the sort of sugar that we think of as involved in making things sweet for us. But it is still a sugar in that it is a compound that stores energy and is involved in biological processes that access that energy and allow it to be used by living organisms,” says McGuire. 

After analyzing data from the LIGO, Virgo and KAGRA gravitational wave detectors, MIT researchers have found that 14% of black holes may be second-generation, formed by the merger of two smaller black holes, writes Gayoung Lee for Gizmodo. The scientists “created an analytic model to capture the kind of wobble that would have emerged from second-generation black holes. Around 14% of merging black holes followed this pattern, and the second-generation black holes identified had a very specific range of masses, at around 20 solar masses or 40 solar masses and above,” Lee explains.  

Associate Prof. Areg Danagoulian has developed a satellite equipped with specialized neutron detectors that he hopes will fill the gaps in the 1967 Outer Space Treaty, which bans nuclear weapons in space without a way to verify satellites are not carrying them. “[I]f the concept proves to be practical enough to someone in charge, it could finally give us a way to verify that there really aren’t any nukes floating precariously over our heads,” writes Luis Prada for Vice. 

Financial Times reporter Michael Peel features CubeSat, a proposed satellite sensor by Associate Prof. Areg Danagoulian, able to identify hidden nuclear weapons in space.  “If one state suspects another of placing a nuclear weapon in orbit, the absence of a verification mechanism makes the crisis harder to manage,” says Danagoulian. “If a bad-faith actor knows that their attempt will be discovered via inspection, they will be more likely to decide it's not worth pursuing.” 

Gizmodo’s Ellyn Lapointe reports on a new paper from Associate Prof. Areg Danagoulian, which offers a  solution to verifying satellites aren’t carrying hidden nuclear weapons in space: an inspector satellite able to indicate the presence of uranium from neutron signals via sensor technology. Danagoulian’s proposal seeks to fill the gaps of The Outer Space Treaty (OST), established in 1967 and signed by 118 countries to ban nuclear weapons in space, which “has always lacked robust means of verification for space-based nuclear threats,” says Danagoulian. 

In a new study, Associate Prof. Areg Danagoulian proposes a satellite-based sensor that could monitor suspicious craft for signs of nuclear activity in space with 99% accuracy, reports Andrew Paul for Popular Science. “You can fake intelligence, but you can’t fake physics,” says Danagoulian. “The goal right now is to get national labs to use this work for their own research, and to get policymakers to seriously consider this technology as a potential part of national technical means.” 

Scientific American’s Adam Kovac highlights a paper by Associate Prof. Areg Danagoulian that proposes a satellite to detect and police hidden nuclear weapons in space by detecting spallation, the ejection of neutrons, from the bombardment of high energy protons, and uranium atoms. “If you detect those neutrons, that itself can be a telltale sign that there is an unusual amount of uranium on the satellite, and it’s most likely to be a nuclear weapon,” Danagoulian says.

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.” 

Associate Prof. Zachary Cordero speaks with Live Science reporter Larissa G. Capella about why cold welding—a process in which metals fuse together— can easily occur in space and the hazards it can pose. “If there is cold welding, things can become stuck in place,” says Cordero. “If you have a deployable structure and there's cold welding, you might freeze the mechanism, or a door might become locked, or something might become immobilized, which you don't want.” 

Prof. David Kaiser joins GBH “Particles of Thought” podcast host Dr. Hakeem Oluseyi to discuss his hunt for primordial black holes. “It’s a lot easier to find stuff coming off of a very bright, hot source, than a cold, dim one. So, the Hawking temperature of a black hole that has the same mass as our sun, or a little bigger would be so cold we would literally never be able to measure [its] radiation,” says Kaiser. “You’ll never see it [Hawking Radiation] from stellar collapse black holes, you’ll never see it from supermassive black holes, or even colder. The only hope to ever see it would be a smaller mass black hole.”

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.”

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. Richard Binzel speaks with CBS Boston about the success of the Artemis II mission and the future of space exploration. "It's exciting we have humans back in space again," Binzel shared. "It's a real test of a spaceflight system. Surviving reentry and landing safely. That's the real accomplishment here. Showing we can go to the moon but also come back safely."
