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.”

Prof. Dava Newman speaks with USA Today reporter Sara D. Wire about NASA’s plans to return to the moon and, hopefully, Mars in the 2030s.  The “moon is a three-day trip," Newman explains. "Mars, you need eight months. Those are very different targets.” 

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.”

Prof. Danielle Wood speaks with CNBC reporter Laya Neelakandan about NASA’s Artemis III, the United States’ first venture back to the moon in over 50 years, which will carry the first female and first Black astronaut to the Moon. “NASA’s been thinking through this whole process, two decades’ worth, of what we’re going to do is prepare the government to focus on these harder, next-generation missions and be able to do things that are not already demonstrated,” says Wood. 

Prof. Anna-Christina Eilers and postdoctoral associate Rohan Naidu speak with Scientific American reporter Rebecca Boyle about the discovery and study of Little Red Dots, mysterious, red spots that showed up in images from the James Webb Space Telescope.  The dots, which astronomers dated to 600 million years after the big bang, “are in every single image the telescope takes,” says Naidu. “We have to find out about them if we want to tell a complete story about the early universe." 

A new study by Prof. Sara Seager and her colleagues has found a solar system that contradicts the patterns commonly “seen across the galaxy and in our own solar system,” reports Jacopo Prisco for CNN. The study offers “some of the first evidence for flipping the script on how planets form around the most common stars in our galaxy,” says Seager. “Even in a maturing field, new discoveries can remind us that we still have a long way to go in understanding how planetary systems are built.”  

Using the James Webb Telescope, postdoctoral associate Rohan Naidu and his colleagues have captured a glimpse of Galaxy MoM-z14, which existed 280 million years after the Big Bang, and could provide clues as to what the universe was like during its infancy and how it has evolved over time, reports Passant Rabbie for Gizmodo. “We can take a page from archeology and look at these ancient stars in our own galaxy like fossils from the early universe,” says Naidu. “Except in astronomy we are lucky enough to have Webb seeing so far that we also have direct information about galaxies during that time.” 

A new analysis conducted by postdoctoral associate Rohan Naidu and his colleagues has found evidence that suggests “little red dot” galaxies may contain baby black holes, reports Alex Wilkins for New Scientist. “In ordinary black holes, what you actually see with your eyes is the tip of the iceberg of the total energy that is coming out of the system, but the little red dots we now understand should really be thought of as these puffed-up black hole stars,” says Naidu. “It seems that most of their energy is coming out at these wavelengths that we see with our eyes, so what you see is what you get.” 

A new report co-authored by Prof. Dava Newman and Lindy Elkins-Tanton '87, SM '87, PhD '02 explores the highest-priority science objectives for the first human missions to Mars, reports Eric Berger for Ars Technica. “We’re searching for life on Mars. The answer to the question ‘are we alone’ is always going to be ‘maybe,’ unless it becomes yes,” explains Newman. 

Prof. Paulo Lozano has received funding from NASA’s University SmallSat Technology Partnership (USTP) to “explore integration of tiny electronic thrusters – a propulsion system using electrical power to propel spacecraft – onto satellites, reports Robin Roenker for USA Today. “We have many ideas (for application),” says Lozano. “One is to send tens or even hundreds of these small satellites to the asteroid belt to help study and characterize the asteroids’ surface structures.” 

Using molecular evidence buried in rocks, researchers at MIT suggest that some of the Earth’s first living creatures are ancestors of the modern sea sponge, reports Ashley Fike for Vice. “The discovery suggests the earliest animals were simple, filter-feeding organisms that slowly cleaned the seas while the rest of the evolution was still figuring itself out,” says Fike. “These early sponges likely had no skeletons, nerves, or eyes – just porous bodies that absorbed water and nutrients. Yet they paved the way for everything that came next, from insects to mammals to us.” 

A new study by MIT researchers suggests sea sponges may have been the “first animals to inhabit the Earth,” reports Maria Azzura Volpe for Newsweek. “In their work, the researchers linked so-called ‘chemical fossils’ found in ancient rocks to the ancestors of a class of modern-day sea sponges known as demosponges,” explains Volpe. “These chemical fossils—the molecular remnants of once-living organisms that have been buried, transformed, and preserved in sediment over time—were discovered in rocks that date back to more than 541 million years ago, during the Ediacaran Period.” 

MIT researchers have uncovered new evidence that suggests some of Earth’s first living creatures are ancestors of the modern sea sponge, reports Andrew Paul for Popular Science. The researchers identified 541 million-year-old chemical fossils embedded in sediment that they believe may indicate that some of Earth’s earliest creatures were the ancient relatives of today’s sea sponges. 

Visiting Scholar Ariel Ekblaw SM '17, PhD '20 speaks with WBUR’s On Point host Meghna Chakrabarti about her academic career, the space industry and her new non-profit company the Aurelia Institute. The company is “dedicated to building humanity’s future in space for the benefit of the earth,” says Chakrabarti. Additionally, the company plans to use “space infrastructure, satellites, and large scale space structures in orbit to do really profound things for day-to-day life on Earth,” adds Ekblaw. 

Using the James Webb Telescope, researchers at MIT and elsewhere are studying the potential presence of “an Earth-like atmosphere on an exoplanet for the first time,” reports Jacopo Prisco for CNN. “The planet is part of a planetary system about 40 light-years away from Earth called TRAPPIST-1,” explains Prisco.
