A study conducted by Prof. Susan Solomon and her colleagues has found that unlike CFCs, smoke destroys the ozone in a more roundabout way, creating concerns due to the impact of the Australian bushfires of 2019-2020, reports Krystal Vasquez for EOS. “Because of the sheer scale of the event [the Australian bushfires] massive amounts of smoke penetrated the normally pristine upper stratosphere,” writes Vasquez.
Researchers from MIT and other institutions have developed a new simulation that illuminates how stars formed in the early universe, reports Martin Finucane for The Boston Globe. “It was a neutral, dark cosmos that became bright and ionized as light began to emerge from the first galaxies,” explains Aaron Smith, a NASA Einstein Fellow in MIT’s Kavli Institute for Astrophysics and Space Research.
MIT researchers have developed a new simulation of the early universe, shedding light onto the period when the first stars were formed, reports Audrey Carleton for Vice. “Using existing models of the early universe and of cosmic dust, matched with new code created to interpret how light and gas interacted with one another, they created a visual depiction of the growth of the universe,” writes Carleton.
NASA astronaut Raja Chari SM ’01 and European Space Agency (ESA) astronaut Matthias Maurer performed a spacewalk to help maintain the crucial cooling systems aboard the International Space Station (ISS), reports Ed Browne for Newsweek. “Spacewalks are an important part of life on the space station,” writes Browne. “Also called an extravehicular activity (EVA), a spacewalk is when an astronaut or cosmonaut gets out of the ISS whilst wearing a pressurized and oxygenated space suit that protects them from the vacuum of space.”
Prof. Sara Seager has been awarded one of NASA’s Innovative Advanced Concepts (NIAC) awards, which will help fund her project aimed at sending an orbiter that deploys an inflatable probe to Venus, as part of an effort to search for habitability or signs of life, reports Ramin Skibba for Wired. “This search for signs of life on Venus has been around for a long time, and now the stars are aligned to start taking it seriously,” says Seager.
Prof. Susan Solomon speaks with Wall Street Journal reporter Nidhi Subbaraman about her research and another recent study that provides evidence wildfire smoke poses a threat to the ozone layer. “It’s fair to say that, at least for a few months, these wildfires canceled out the last decade of all the efforts that we put in over the Montreal Protocol,” says Solomon. “I think there’s every reason to believe this is going to happen more often, and it’s going to act to slow down the recovery of the ozone depletion.”
Smoke from Australian wildfires in 2019 and 2020 appears to have contributed to the breakdown of the ozone layer, according to a new study by MIT scientists, reports Sharon Udasin for The Hill. “The new study establishes the first direct link between wildfire smoke and ozone depletion,” writes Udasin.
Daily Beast reporter Miriam Fauzia writes that a new study by MIT scientists finds that smoke particles from wildfires are slowing the recovery of the ozone layer.
BBC News correspondent Helen Briggs writes that MIT scientists have found that increasing wildfires may slow the recovery of the ozone layer. "All the hard work that the world went to to reduce chlorofluorocarbons (ozone-depleting chemicals once used in aerosol sprays) is not paying off as well in the areas that experience extreme wildfires," explains Prof. Susan Solomon. "The best hope would be that we reduce global warming gases also and stop increasing the wildfires, but that's obviously more difficult."
A new study by MIT scientists finds that smoke emitted into the atmosphere from Australian wildfires in 2019 and 2020 resulted in depletion of the ozone layer, reports Donna Lu for The Guardian. The findings suggest “rising fire intensity and frequency due to the climate crisis may slow the recovery of the ozone layer.”
MIT astronomers have observed the dark side of a football-shaped exoplanet known as WASP-121b and found that it may have metal clouds made up of iron, corundum, and titanium, reports Isaac Schultz for Gizmodo. “The vastly different temperatures on either side of the planet make a dynamic environment for the various molecules floating around the atmosphere,” writes Schultz. “In the daytime, water gets ripped apart by the nearly 5,000° Fahrenheit heat and blown to the night side of the planet by 11,000-mile-per-hour winds.”
CNN reporter Ashley Strickland writes that MIT researchers have observed the dark side of an exoplanet that is 855 light years from Earth and found that the gas giant may have metal clouds and rain containing liquid gems. The researchers found that the “exoplanet has a glowing water vapor atmosphere and is being deformed into the shape of a football due to the intense gravitational pull of the star it orbits,” writes Strickland.
One year after NASA’s Perseverance rover successfully landed on Mars, scientists are preparing to investigate a dried-up river delta along the west rim of the Jezero crater to search for rocks and microscopic fossils, reports Kenneth Chang for The New York Times. If Perseverance undercovers fossils, “we have to start asking whether some globs of organic matter are arranged in a shape that outlines a cell,” says Prof. Tanja Bosak.
Prof. Sara Seager speaks with Tom Metcalfe of NBC News about the Venus Life Finder missions, which will carry a robotic space payload partially funded by MIT alumni to Venus to search for signs of life in the planet's atmosphere. “Space is becoming cheaper in general, and there is more access to space than ever before,” says Seager.
TESS, a NASA mission led and operated by MIT, has discovered over 5,000 planets candidates outside of our solar system, reports Ed Browne for Newsweek. “This time last year, TESS had found just over 2,400 TOIs (TESS Objects of Interest),” says postdoctoral associate Michelle Kunimoto. “Today, TESS has reached more than twice that number – a huge testament to the mission and all the teams scouring the data for new planets.”
