A study co-authored by MIT researchers shows that as the sun loses mass its gravitational pull is becoming weaker, reports Kastalia Medrano for Newsweek. “The study demonstrates how making measurements of planetary orbit changes throughout the solar system opens the possibility of future discoveries about the nature of the sun and planets,” explains Maria Zuber, MIT’s vice president for research.
In an article for Physics Today, Prof. Anna Frebel details the formation of the heaviest elements. While scientists previously thought that supernova explosions were responsible for the creation of elements heavier than iron, Frebel notes that evidence from LIGO and from a faint galaxy known as Reticulum II suggest, “neutron-star mergers are the universe’s way to make elements such as gold and platinum.”
Boston Globe reporter Marin Finucane writes that with the help of around 10,000 citizen scientists, a team of astronomers has discovered five planets outside our solar system. “It’s exciting because we’re getting the public excited about science, and it’s really leveraging the power of the human cloud,” says Prof. Ian Crossfield of the discovery.
Daniel Michaels and Andy Pasztor of The Wall Street Journal highlight Prof. Dava Newman’s BioSuit in an article about upgrades and improvements in space suits. Regarding the skintight, flexible suit, Michaels and Pasztor write that Newman’s suit differs in that, “pressure comes not from gas but from tiny electrically activated coils embedded in fabric.”
In this PBS NewsHour article and video, Nsikan Akpan spotlights Prof. Paulo Lozano’s work developing tiny satellites equipped with ion thrusters that could eventually help researchers explore asteroids or Mars. Prof. Kristina Lemmer of Western Michigan University notes that Lozano’s system, “is probably the frontrunner for the possibility for deep space missions.”
National Geographic reporter Christina Nunez writes that MIT researchers have found that the total solar eclipse in August 2017 caused boat-like ripples in the Earth’s atmosphere. The researchers explained that the findings reveal, “complex interconnections between the sun, moon, and Earth's neutral atmosphere and ionosphere.”
Prof. Emeritus Rainer Weiss has been named to The Boston Globe’s list of the 2017 Bostonians of the Year for his work starting a new revolution in astronomy. Globe reporter Eric Moskowitz notes that Weiss, “shared the Nobel Prize for Physics for conceiving and shepherding a set of observatories that allowed scientists to prove Einstein’s assertion about gravitational waves.”
The discovery of the oldest and most distant black hole ever detected has provided a team of astronomers new insights into our universe, writes Alyssa Meyers for The Boston Globe. “In some sense, what we’ve done is determine with a high degree of accuracy when the first stars in the universe turned on,” explains Prof. Robert Simcoe.
The discovery of the oldest and most distant black hole ever observed could provide scientists with insights into the early stages of our universe, reports Will Dunham for Reuters. “This object provides us with a measurement of the time at which the universe first became illuminated with starlight,” explains Prof. Robert Simcoe.
NPR’s Nell Greenfieldboyce reports that scientists have discovered the most distant supermassive black hole every discovered, and that the findings are shedding light on when starlight first appeared in our universe. "We have an estimate now, with about 1 to 2 percent accuracy, for the moment at which starlight first illuminated the universe,” explains Prof. Robert Simcoe.
USA Today reporter Doyle Rice writes that a team of astronomers, including several from MIT, has discovered the oldest and most distant supermassive black hole ever detected. “The black hole resides in a quasar and its light reaches us from when the universe was only 5% of its current age — over 13 billion years ago,” explains Rice.
Prof. Nergis Mavalvala speaks with Massive reporter Prabarna Ganguly about her work engineering high-precision laser beams to detect signals from deep space, the long hunt for gravitational waves and her hopes for future generations of scientists. Ganguly writes that Mavalvala is, “one of the stalwarts in a long, arduous, and deeply human discovery of faraway perturbations rippling through the universe.”
Los Angeles Times reporter Amina Khan writes that researchers from the LIGO Scientific Collaboration have identified gravitational waves emitted from the smallest black hole they have detected. “Its mass makes it very interesting,” explains Prof. Salvatore Vitale. The discovery, he adds, “really starts populating more of this low-mass region that [until now] was quite empty.”
In an article for The Washington Post, Prof. Marcia Bartusiak writes about Scott Kelly’s new memoir of his record-setting year on the International Space Station. Bartusiak writes that the book, “offers Earthlings an informative and gripping look at both the adventures and day-by-day experiences of living in a metal container that is orbiting Earth at 17,500 mph.”
WHDH speaks with MIT staff member Maia Weinstock, who designed the original concept for the Women of NASA LEGO set. Weinstock explained that she is “really excited to see teachers and parents and kids tell me their stories of how they are going to use the set.”
