Space, astronomy and planetary science

MIT physicists have found that “the presence of a tiny black hole speeding through the solar system could be identified by the gentle gravitational nudge it exerted on the Earth and other planets, which would alter their orbital paths by no more than a few feet,” reports Noah Haggerty for The Los Angeles Times. “It’s just fantastic that the most conceptually conservative response is to say, ‘It’s just super tiny black holes that were made a split second after the Big Bang,’” says Prof. David Kaiser. “It’s not inventing new forms of matter that have not yet been detected. It’s not changing the laws of gravity.”

A new study by MIT researchers suggests that miniscule black holes could briefly wobble the orbit of Mars and that these tiny black holes may pass through our solar system once every decade or so, reports Jess Thomson for Newsweek. “The researchers modeled the orbits of every large body in the solar system,” writes Thomson, “and found that tiny wobbles in the orbit of Mars could indicate one of the asteroid-mass black holes passing through.”

Science News reporter Emily Conover spotlights a new study by MIT researchers that proposes a new method to search for microscopic primordial black holes, which, if they exist, “could explain some or all of the universe’s dark matter.” The researchers suggest that when a primordial black hole passes close to a planet, it could “produce noticeable effects despite its tiny size.”
 

Researchers at MIT and elsewhere have discovered an exoplanet that “is 50% larger than Jupiter and as fluffy as cotton candy,” reports Aylin Woodward for The Wall Street Journal. “Basically, for over 15 years now, the astronomy community has been puzzled by a category of gas giants that are bigger than what they should be given their mass,” explains Prof. Julien de Wit. 

In the Wall Street Journal, Cady Coleman '83, a former NASA astronaut and U.S. Air Force colonel, recalls how a talk by astronaut Sally Ride at MIT  inspired her to shoot for the stars. “In her quiet way, Sally Ride shattered assumptions I didn’t know I had,” Coleman writes. “It is extraordinary what a difference it can make to see someone like you doing things you might never have considered doing.”

Prof. Olivier de Weck speaks with Boston 25’s Daniel Coates about the two NASA astronauts on the International Space Station awaiting news on when they will return to Earth due to concerns surrounding the capsule they traveled in. De Weck notes that during their wait, the astronauts are “being put to good work, they’re helping with experiments, they’re helping with the station, they’re in contact with their families, because there is fairly good internet connection on ISS."

MIT scientists have solved a decades old mystery by demonstrating impact vaporization is the primary cause of the moon’s thin atmosphere, reports Eric Lagatta for USA Today.  The findings, “have implications far beyond determining the moon's atmospheric origins,” writes Lagatta. “In fact, it's not unthinkable that similar processes could potentially be taking place at other celestial bodies in the solar system.”

By analyzing isotopes of potassium and rubidium in the lunar soil, Prof. Nicole Nie and her team have demonstrated that micrometeorite impacts are the main cause of the moon’s thin atmosphere, reports Isabel Swafford for National Geographic. “Understanding the space environments of different planetary bodies is essential for planning future missions and exploring the broader context of space weathering,” says Nie.

Newsweek reporter Jess Thomson spotlights, Prof. Nicole Nie’s research uncovering the origins of the moon’s thin atmosphere. “The researchers described how lunar samples from the Apollo missions revealed that meteorites of varying sizes have constantly hit the moon's surface, vaporizing atoms in the soil and kicking them up into the atmosphere,” writes Thomson. “The constant hitting of the moon replenishes any gases lost to space.” 

By analyzing lunar soil samples, MIT scientists have found that the moon’s thin atmosphere was created by meteorite impacts over billions of years, reports Will Dunham for Reuters. “Many important questions about the lunar atmosphere remain unanswered,” explains Prof. Nicole Nie. “We are now able to address some of these questions due to advancements in technology.” 

MIT scientists analyzed lunar soil samples and discovered that meteorite impacts likely created the moon’s thin atmosphere, reports Nicola Davis for The Guardian. “Our findings provide a clearer picture of how the moon’s surface and atmosphere interact over long timescales, [and] enhance our understanding of space weathering processes,” explains Prof. Nicole Nie. 

The final round of the Zero Robotics competition at the MIT Media Lab featured high school students from around the country facing off in a programming challenge using the SPHERES satellites aboard the International Space Station, reports Glenn Jones for NBC Boston. The event “welcomed about 70 middle schoolers from diverse backgrounds to participant in the finals of a robotics competition that featured live dialogue with astronauts on the International Space Station.”

Visiting Scientist Ariel Ekblaw speaks with Scientific American’s Andrew Chapman about a microgravity water cooker called the H0TP0T, part of a mock space habitat set to open in Boston in early August. For the project “Ekblaw and a colleague interviewed nearly two dozen astronauts—who often mentioned better cooking options and tastier food as important ways to improve their well-being,” Chapman explains.

CNN’s Ashley Strickland reports on the discovery of an exoplanet on the path to becoming a “hot Jupiter,” providing clues about the evolution of these massive Jupiter-like planets closely orbiting their host stars. As Prof. Sarah Millholland explains: “This system highlights how incredibly diverse exoplanets can be. They are mysterious other worlds that can have wild orbits that tell a story of how they got that way and where they’re going.”

Prof. Richard Binzel organized a centennial celebration for the Johnstown meteorite, which was seen crashing into Earth on July 6, 1924 in Weld County, Colorado, and later “became a link to understanding a whole class of meteorites,” reports Elizabeth Gamillo for Astronomy. “Binzel describes the Johnstown rock not as the meteorite that launched a thousand ships, but one that instead launched one major mission to the asteroid belt,” writes Gamillo.
