Boston Globe reporter Charlie McKenna writes that MIT researchers have used the spin of black holes detected by the LIGO and Virgo detectors to search for dark matter. "In reality, there is a much broader set of theories that predict or relies on the existence of these very ultra-light particles,” says Prof. Salvatore Vitale. “One is dark matter. So they could be dark matter. But they could also solve other open problems in particle physics.”
A new study by MIT researches finds that some masses of boson particles don’t actually exist, reports Monisha Ravisetti for The Academic Times. “[Bosons] could be dark matter particles, or they could be something that people call axions, which are proposed particles that could solve problems with the magnetic bipoles of particles,” says Prof. Salvatore Vitale. “Because they can be any of these things, that means they could also have an incredibly broad range of masses.”
Writing for The Boston Globe, M.J. Andersen highlights Prof. Sara Seager’s book, “The Smallest Lights in the Universe.” Seager’s memoir is "half hymn to the stars and half guide to grief recovery,” writes Andersen. “Lured by her faith in finding life elsewhere, she continued her research on exoplanets — versions of other star-orbiting Earths — and methods for detecting them.”
Prof. Sara Seager speaks with Washington Post reporter Timothy Bella about the search for exoplanets and the James Webb Telescope. “I just remember seeing the stars and being overwhelmed by the beauty and the vastness and the mysteriousness of it,” recalled Seager, of a camping trip with her father that helped inspire her interest in space. “There’s something almost terrifying about it at the same time as it being so beautiful, because yeah, it’s so unknown, and it seems like it goes on forever.”
Prof. Alan Lightman’s new book, “Probable Impossibilities: Musings on Beginnings and Endings” tackles “big questions like the origin of the universe and the nature of consciousness, always in an entertaining and easily digestible way,” writes Andrew Crumey for The Wall Street Journal.
Postdoc Tansu Daylan speaks with CNN reporter Ada Wood about his work mentoring two high school students, and their discovery of four new exoplanets. "When it comes to studying by comparison — that is, studying the atmospheres of planets beyond the solar system around sun-like stars — this is probably one of the best targets that we will ever get," says Daylan.
Reporting for CBS News, Sophie Lewis spotlights how MIT astronomers have uncovered evidence of what may be one of the earliest incidences of galactic cannibalism in a dwarf galaxy called Tucana II. “The findings suggest that the earliest galaxies in the universe were much more massive than previously believed,” writes Lewis.
CNN reporter Ashley Strickland writes that astronomers have identified an extended dark matter halo around Tucana II, an ancient dwarf galaxy. "This probably also means that the earliest galaxies formed in much larger dark matter halos than previously thought," says Prof. Anna Frebel. "We have thought that the first galaxies were the tiniest, wimpiest galaxies. But they actually may have been several times larger than we thought, and not so tiny after all."
Astronomers have uncovered evidence of an extended dark matter halo around an ancient galaxy located about 163,000 light years from Earth, reports Isaac Schultz for Gizmodo. “We know [dark matter] is there because in order for galaxies to remain bound, there must be more matter than what we see visibly, from starlight,” explains graduate student Anirudh Chiti. “That led to the hypothesis of dark matter existing as an ingredient that holds galaxies together.”
UPI reporter Brooks Hays writes that MIT researchers have discovered an extended dark matter halo encircling an ancient dwarf galaxy about 163,000 light years from Earth. “The findings suggest many more of the cosmos' earliest galaxies may have formed within expansive dark matter halos,” writes Hays.
Mashable spotlights how two high school students, who were part of Student Research Mentoring Program (SRMP) at the Harvard-Smithsonian Center for Astrophysics (CfA) and MIT, have discovered four new exoplanets. “Both the students took guidance from mentor Tansu Daylan, a postdoc at the MIT Kavli Institute for Astrophysics and Space Research, and helped the students study and analyze data from the Transiting Exoplanet Survey Satellite (TESS).”
Andrea Ghez ’87 speaks with Carol Stabile of Ms. magazine about the importance of representation in encouraging more women and people of color to pursue careers in STEM fields. Ghez recalls how her science teacher in high school encouraged her to apply to MIT, describing the experience as “'a lovely early lesson in how to persevere,’ that helped her to develop what she described as the muscle to persevere, and to turn problems into opportunities to grow and learn.”
Physics World selected a study by researchers from MIT’s LIGO Lab that shows quantum fluctuations can jiggle objects as large as the mirrors of the LIGO observatory as one of the top 10 breakthroughs of the year. “The research could lead to the improved detection of gravitational waves by LIGO, Virgo and future observatories,” notes Hamish Johnston for Physics World.
Research scientist Clara Sousa-Silva speaks with Wired reporter Abigail Beall about phosphine, a molecule that she has spent the past decade investigating. “Phosphine is a horrific molecule, it’s foul in every way,” she says. “It’s almost immoral, if a molecule can be.”
A team of astronomers, including MIT researchers, have identified fast radio burst emanating from a magnetar in our galaxy, reports Doyle Rice for USA Today. “The radio pulses are the closest ones detected to date, and their proximity has allowed the team to pinpoint their source.”
