Mary Beth Griggs writes for Popular Science about a new Nature study where researchers have identified cold hydrogen dating back to 180 million years post-big bang. “Some of the radiation from the very first stars is starting to allow hydrogen to be seen,” says Alan Rogers of the Haystack Observatory.
Hydrogen detected via radio waves by MIT researchers indicates the presence of stars 180 million years after the Big Bang, reports Will Dunham of Reuters. The radio waves also indicate that the universe was likely twice as cold as was previously believe, which Research Affiliate Alan Rogers suggests “might be explained by interaction between the gas and dark matter.”
Alan Rogers of MIT's Haystack Observatory co-authored a study that identifies the earliest traces of hydrogen in the universe. The gas is “from 180 million years after the Big Bang,” writes Elise Takahama for The Boston Globe, which suggests that stars would have appeared around this time, creating a “cosmic dawn.”
Gizmodo reporter Ryan Mandelbaum writes that a new study co-authored by MIT researchers confirms Einstein’s theory that the sun is losing mass. Mandelbaum writes that, “seven years of data, combined with observations of how the Sun uses up its hydrogen fuel, reveal that the Sun is slowly, every so slightly, loosening its grasp on Mercury.”
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.
