Stars

Postdoctoral Associate Rohan Naidu joins John Batchelor and David Livingston, hosts of the “Hotel Mars” podcast, to discuss his research discovering black hole stars from little red dots using NASA’s James Webb Space Telescope. “When we first discovered the little red dots, we assumed that red means dust, and so the idea was that the little red dots are the kind of black holes that we see in our backyard,” says Naidu. “But now we have this paradigm shift where we are realizing that red does not mean dust. Red could mean that you have this black hole star kind of object where all the blue light is being soaked up in this dense star-like cocoon.” 

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. 

Graduate student Megan Masterson speaks with CBS Eye on the World hosts John Batchelor and David Livingston about her research on tidal disruption events. “These events were first theorized in the 1970s, first discovered in the 1990s with x-ray wavelengths,” explains Masterson. “But today, what James Webb is doing is allowing us to detect these events in the infrared band. And so, what we’re seeing here are previously dormant black holes that were kind of lying at the center for their galaxies doing pretty much nothing suddenly become active.” 

Using the Hubble Space Telescope, Prof. Julien de Wit and his colleagues have “detected microflares coming from the TRAPPIST-1 star every hour or so that last for several minutes,” reports Alex Wilkins for New Scientist. “These tiny bursts of radiation appear to interfere with our ability to observe the light that passes through the planets’ atmospheres – if they exist – thwarting the main method of detecting what chemicals might be in any atmospheres,” explains Wilkins. 

Researchers at MIT and elsewhere have discovered a “black-hole triple, the first known instance of a three-body system that includes a black hole, which is not supposed to be part of the mix,” reports Dennis Overbye for The New York Times.  The researchers propose that the black hole “could have resulted from a sort of immaculate conception whereby the progenitor star disappeared from the universe without any fireworks.”

Astronomers from MIT and elsewhere have “identified a black hole that appears to have come into being through the collapse of the core of a large star in its death throes, but without the usual blast,” explains Will Dunham for Reuters. “Black holes have previously been spotted orbiting with one other star or one other black hole in what are called binary systems,” explains Dunham. “But this is the first known instance of a triple system with a black hole and two stars.”

Researchers from MIT and elsewhere have discovered a black hole triple – a black hole with two orbiting stars around it at varying distances – for the first time, reports Jess Thomson for Newsweek. The researchers believe this “first-of-its-kind discovery could help unravel the mysteries of how black holes form and how they enter into binaries or triples,” writes Thomson. 

Popular Science reporter Laura Baisas writes that MIT physicists have discovered, for the first time, a black hole triple. “Since the new triple system includes a very far-off star, the system’s black hole was potentially born through [a] gentler direct collapse,” writes Baisas. “While astronomers have been observing violent supernovae for centuries, this new triple system may be the first evidence of a black hole that formed from this more gentle process.” 

Physicists from MIT and Caltech have discovered a black hole triple system, “consisting of three bodies spinning around each other about 7,800 light-years from Earth,” writes Isaac Schultz for Gizmodo. Schultz notes that the finding “pushes the envelope,” revealing “a system with one black hole and two stars—a configuration never seen before.”

Boston Globe reporter Nick Stoico spotlights how researchers from MIT and Caltech have observed a “black hole triple” for the first time. “This one is satisfying because it’s kind of a simple discovery,” explains postdoctoral associate Kevin Burdge. “It’s just looking at a picture, and I think it reminds a lot of astronomers that there’s more to the job than just analyzing complicated data. You shouldn’t forget to do the simple things, like just look with your own eyes at some pictures and see what you find.” 

Researchers at MIT and elsewhere have found a connection between “the bursts and tidal disruptions events” of black holes, research that could help "astrophysicists understand the extreme environments around supermassive black holes, as well as the occupants of those environments,” reports Isaac Schultz for Gizmodo. “There had been feverish speculation that these phenomena were connected, and now we’ve discovered the proof that they are,” says Research Scientist Dheeraj Pasham. “It’s like getting a cosmic two-for-one in terms of solving mysteries.”
