The Boston Globe

Researchers at MIT have discovered 18 supermassive black holes that “are tearing apart nearby stars in ‘oddball’ tidal disruption events,” reports Ava Berger for The Boston Globe. Graduate student Megan Masterson says, “the events are powerful tools to understand the most extreme parts of our universe. They happen about once every 50,000 years, and help scientists learn more about the supermassive black hole at the center of the Milky Way, and black holes in general.”

Newsweek

MIT researchers have discovered 18 new tidal disruption events (TDEs), “which are huge bursts of energy released as a star is shredded by a black hole,” reports Jess Thomson for Newsweek. “These new discoveries have also helped scientists learn more about what TDEs really are and where they occur,” explains Thomson. “The previous stock of TDEs had only been found in a rare form of galaxy known as a ‘post-starburst’ system, which once created a number of stars but has since stopped.”

MIT researchers have discovered that “stars at the edge of our home galaxy appear to be moving more slowly than expected,” reports Jess Thomson. This discovery “implies that the galaxy itself may be structured differently from how scientists first thought, with the core of the Milky Way possibly containing less dark matter and, therefore, being lighter in mass than first assumed,” explains Thomson.

Forbes

Forbes contributor Jamie Carter spotlights a new study co-authored by MIT scientists that suggests, “the absence of carbon dioxide in a rocky planet’s atmosphere—relative to others in the same star system—may indicate the presence of liquid water on the planet’s surface.”

Quanta Magazine

Using the James Webb Space Telescope (JWST), astronomers at MIT and elsewhere have discovered that the young cosmos hosted a large number of tempestuous galaxies with large black holes at their cores, reports Charlie Wood for Quanta Magazine. “The exact numbers and the details of each object remain uncertain, but it’s very convincing that we’re finding a large population of accreting black holes,” says Prof. Anna-Christina Eilers. “JWST has revealed them for the first time, and that’s very exciting.”

The Washington Post

Researchers at MIT have discovered that the ocean’s color has changed considerably in the last 20 years and is “another warning sign of human-driven climate change,” reports Maria Luisa Paul for The Washington Post. “These ecosystems have taken millions of years to evolve together and be in balance,” says Senior Research Scientist Stephanie Dutkiewicz. “Changes in such a short amount of time are not good because they put the whole ecosystem out of balance.”

Fast Company

MIT researchers have found that over the past two decades, the color of the world’s oceans has changed significantly, reports Talib Visram for Fast Company. The change “is likely due to human-induced climate change,” explains Visram. “The color shifts matter in that they signal changes in ecosystem balance, which have the power to disrupt fragile marine food webs.”

CNN

CNN reporter Jack Guy spotlights a new study co-authored by researchers at MIT, which shows that the ocean’s color has changed considerably over the last 20 years and human-caused climate change is likely responsible. “All changes are causing an imbalance in the natural organization of ecosystems,” says senior research scientist Stephanie Dutkiewicz. “Such imbalance will only get worse over time if our oceans keep heating.”

Popular Science

Researchers at MIT and elsewhere have discovered that the ocean’s hue has changed significantly over the last 20 years, reports Laura Baisas for Popular Science. “A shift in ocean color is an indication that ecosystems within the surface may also be changing,” writes Baisas. “While the team can’t point to exactly how marine ecosystems are changing to reflect the shift, they are quite sure that human-induced climate change is likely behind it.”

Bloomberg

A new study led by a team including researchers at MIT has found that more than half of the world’s ocean has changed color in the last 20 years, reports Coco Liu for Bloomberg. “The color shift could be caused by changes in plankton communities that are critical to the marine food chain,” writes Liu. “And biodiversity isn’t the only thing at stake: The shift could also affect how much carbon dioxide the ocean takes up, since different types of plankton have different abilities to absorb it."

Forbes

Researchers from MIT have developed a new satellite observation technique that can help gauge the strength of ancient rivers on Mars and active liquid methane rivers on Titan, Saturn’s largest moon, reports Jamie Carter for Forbes. “What’s exciting about Titan is that it’s active, and on Mars, it gives us a time machine, to take the rivers that are dead now and get a sense of what they were like when they were actively flowing,” says Prof. Taylor Perron. “With this technique, we have a method to make real predictions for a place where we won’t get more data for a long time.”

Gizmodo

Using a new satellite observation technique, researchers from MIT and elsewhere have determined the flow of dried-up rivers on Mars and currently active liquid methane rivers on Titan, Saturn’s largest moon. “Both kinds are of scientific interest because they could reveal the role rivers play in shaping the worlds’ environments,” reports Isaac Schultz for Gizmodo.

PBS

Researchers from Lincoln Laboratory and NASA are working on the TROPICS mission to study tropical cyclones, reports Bella Isaacs-Thomas for the PBS NewsHour. “Technology today — finally — allows us to miniaturize these satellites, fly a lot of them and get that temporal update that we’ve been wanting for so long,” explains Laboratory Fellow William Blackwell.

Mashable

Astronomers from MIT and elsewhere have become the first to witness a star consume an entire planet, reports Elisha Sauers for Mashable. “The new study confirms that when a sun-like star nears the end of its life, it expands into a red giant, 100 to 1,000 times its original size, eventually overtaking nearby planets,” explains Sauers. “Such events are thought to be rare, occurring only a few times each year throughout the galaxy.”
