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 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.”
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.”
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."
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.”
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.
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.
Researchers from Lincoln Lab and NASA are working on the TROPICS research mission, an effort to collect meteorological data on tropical storms from mini satellites, reports Daniel Cusick for Scientific American. "Scientists will observe temperature profiles in space that would be favorable to storm formation at the Earth’s surface, then use a weather prediction model and radiometric imagery to better predict how such storms would behave," Cusick writes.
SpaceX Crew-6 Mission Commander Stephen Bowen MS ’93 recently answered questions from Cohasset Public School students live from the International Space Station, reports WBZ. "The Earth is always amazing to look at," Bowen told the students of his experience in space.
Using the James Webb Space Telescope (JWST), postdoc Rohan Naidu and his colleagues will be using a giant cluster of galaxies to “gravitationally magnify the light of some smaller objects up to 750 million years after the big bang,” reports Jonathan O’Callaghan for Scientific American. “The goal is to look for clumps of primordial gas, which could contain clusters of Population III stars—the first stellar generation thought to have lit up the universe,” writes O’Callaghan.
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.”
A team of astronomers, including researchers from MIT, witnessed a star swallowing up an entire planet for the first time, reports Margaret Osborne for Smithsonian Magazine. “For decades, scientists have only been able to witness the before and after of such planetary engulfment,” writes Osborne.
Researchers from MIT and elsewhere have observed, for the first time, a dying star consuming a planet, reports Jack Guy for CNN. “The fact that the solar system planets would get engulfed into the sun in the future was something I had read first in high school, so it was surreal to realize that we may have found the first ever example of catching a similar event in real time,” says postdoc Kishalay De.
Reuters reporter Will Dunham writes that scientists from MIT and elsewhere have “observed a star, bloated in its old age, swallowing a Jupiter-like planet, then expelling some material into space in an energetic belch.” Postdoc Kishalay De notes that "this planet doesn't go out without a fight. Even before it is engulfed whole, our data provides evidence that the planet tries to rip out the star's surface layers with its own gravity. But the star happens to be a thousand times more massive so the planet can't do much and eventually makes the plunge.”
Researchers from MIT, Harvard, Caltech and elsewhere have spotted a hot, Jupiter-sized world being ingested by a sun-like star, reports Kasha Patel for The Washington Post. “The hope is that we would actually be able to use this entire new suite of instruments to try to find every single planet being engulfed in our galaxy in real time,” explains postdoc Kishalay De. “That’s only going to become possible now because of this discovery and together with the availability of instrumentation.”
