MIT researchers have found that the minor planet Chiron may have a system of rings, reports Monte Morin for the Los Angeles Times. The researchers observed Chiron passing in front of a bright star and observed that Chiron's shadow contained some features “that suggested something surrounding the centaur was blocking the light.”
MIT researchers have found that the high temperature of intracluster gas, which condenses to form stars, may be hindering the development of new stars, reports Jonathan O’Callaghan for the Daily Mail. The researchers hope to use the new findings to better understand how stars form in surrounding galaxies.
Asma Khalid profiles Professor Alan Guth for WBUR's “Visionaries” series, which features experts in a variety of fields. Guth reminisces about how a high school teacher fostered his interest in physics, his time as a student at MIT and his development of the theory behind why the universe expanded so quickly after the Big Bang.
Henry Hanks of CNN writes that MIT researchers have found that a protective field around Earth blocks high-energy electrons. “The phenomenon challenges existing theories that these electrons drift into the upper atmosphere and are destroyed by air molecules,” writes Hanks.
Researchers at the MIT Haystack Observatory have discovered that a phenomenon called “plasmaspheric hiss” prevents radiation from reaching Earth, reports Flora Graham for New Scientist. Graham explains that the plasmaspheric hiss is comprised of “very low-frequency electromagnetic waves,” which act like a radiation barrier.
Scientific American reporter Charles Choi writes that MIT researchers have uncovered evidence that magnetic fields played a role in forming the early solar system. "Magnetic fields can introduce viscosity into the disk, essentially making the gas in it more sticky," explains MIT graduate student Roger Fu.
Researchers from MIT have detected the brightest pulsar ever recorded, reports Brook Hays of UPI. “Despite its small dimensions and modest mass, the pulsating dead star is burning with the energy of 10 million suns,” writes Hays.
Dan Vergano of National Geographic profiles Professor Alan Guth’s career in physics. "What always fascinated me about science was the desire to understand what underlies it all, and I think physics is basically the study of that," Guth explains.
“The goal of the simulation is to compare the actual cosmos — viewable via telescope — to the computer-created universe. The comparison will allow scientists to test if their theories on the creation of the universe work,” Salon reporter Sarah Gray writes of Illustris.
In an article posted on the Scientific American website, Elizabeth Gibney details the new computer model developed to simulate the Universe.
“The invisible web of dark matter and energy tying the universe together is recreated to the best of our knowledge, and the elements that make up stars and planets can be observed forming and coalescing,” Coldewey writes in an MSNBC article about Illustris.
Los Angeles Times reporter Deborah Netburn writes about the computer model developed to model the universe. The model is so accurate that, “a mock observation of galaxies from the Illustris model could pass for an image taken by the Hubble Ultra Deep Field Space Telescope,” Netburn reports.
Wired reporter Adam Mann writes about Illustris, the new computer model developed to model the history of the universe. Illustris can handle all elements of the universe’s 330 million light-year span, Mann reports.
Pallab Ghosh reports for BBC News on the new computer model of the universe developed by researchers from MIT and other institutions around the world.
The Associated Press reports on the new computer model of the universe developed by a team of researchers led by MIT Professor Mark Vogelsberger.
