MIT researchers have discovered a cache of diamonds below the surface of the Earth, deeper than any drilling expedition has ventured, reports the Agence France-Presse wire. This discovery was made after “scientists were puzzled by observations that sound waves would speed up significantly when passing through the roots of ancient cratons.”
Using “recorded sound waves from seismic activity like earthquakes and tsunamis,” MIT researchers have found that there may be a quadrillion tons of diamonds under the Earth’s surface, reports Sarah Gray for Fortune. The seismic data provided this information, “because the speed of sound waves changes depending on the temperature, density and composition of the earth they travel through,” explains Gray.
Seth Borenstein of the Associated Press reports that astronomers, led by MIT research scientist Hans Mortiz Guenther, believe they may have witnessed a star devouring a young planet. According to computer simulations, the observed “30-fold increase in iron on the edge of the star” and “pronounced dimming” could be the result of planet devouring.
MIT research scientist Ulrich Faul used seismic data to determine that there may be diamonds underneath the Earth’s surface. “Located over 100 miles below Earth's tectonic plates are ancient, hard rocks called ‘cratonic roots’ that potentially consist of one to two percent diamond — totaling a quadrillion tons,” writes Lilly Price for USA Today.
A study led by MIT research scientist Ulrich Faul finds that diamonds are about 1,000 times more common in the Earth than previously thought, report Ayana Archie and Ralph Ellis for CNN. “The deposits sit some 90 to 150 miles below the Earth's surface, much deeper than current mining machinery allows,” write Archie and Ellis.
A team led by MIT research scientist Ulrich Faul ‘discovered a gigantic cache of diamonds deep beneath the Earth’s surface,’ writes Avery Thompson for Popular Mechanics. While the diamonds are too deep to be mined, “knowing that they’re there helps us learn more about our own planet and what it’s made of,” Thompson notes.
By using sound waves, MIT researchers have discovered that part of Earth’s stable crust may contain diamonds, reports Abbey Interrante for Newsweek. “This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says research scientist Ulrich Faul.
The Transiting Exoplanet Survey Satellite (TESS) took its first picture of the stars as it moved toward its final orbit, reports Brooks Hays of United Press International. “The plethora of stars in the image -- at least 2,000 of them -- showcases the broad perspective provided by TESS's four cameras,” writes Hays.
NASA’s planet-hunting satellite TESS has “snapped its first test shot — an incredibly clear, star-studded image centered on the Southern constellation of Centaurus,” writes Bruce Dorminey for Forbes. “We are truly excited about how well the TESS cameras are working,” said George Ricker, the mission’s principal investigator and a senior research scientist at MIT’s Kavli Institute.
NASA’s recently launched Transiting Exoplanet Survey Satellite (TESS) “will spend the next two years scanning 200,000 stars looking for any exoplanets orbiting them,” explains New Scientist. In about two months, once the satellite is in orbit and its cameras are tested, “there’ll just be a flood of information,” says MIT’s George Ricker, the principal investigator on TESS.
NASA has successfully launched its “planet-hunting” Transiting Exoplanet Survey Satellite, more than a decade after MIT scientists first proposed the idea of a mission like TESS, reports Ashley Stickland for CNN. “NASA believes that TESS will build on Kepler’s momentum and open the study of exoplanets in unprecedented ways,” writes Strickland.
After launching into space on a SpaceX Falcon 9 rocket, “NASA's newest planet-hunter, the TESS space telescope, will observe roughly 85 percent of the sky to find planets orbiting bright, nearby stars,” writes Jay Bennett of Popular Mechanics. "Never underestimate how ingenious nature actually is," said MIT’s George Ricker, who is the principal investigator on TESS.
Loren Grush of The Verge examines the potential findings of NASA’s Transiting Exoplanet Survey Satellite (TESS), which “will stare out at the cosmos searching for never-before-seen worlds” for two years, after launching on April 16. “[W]e’ll have a whole catalog of these planets in an order of priority for follow-up,” says Prof. Sara Seager, deputy science director for TESS.
With the launch of NASA’s Transiting Exoplanet Survey Satellite near, Elise Takahama of The Boston Globe spoke with Roland Vanderspek, a principal research scientist at MIT’s Kavli Institute, about the mission. “I’m hoping we get some really beautiful images,” said Vanderspek, “and enable good science all around the world.”
Los Angeles Times writer Amina Khan examines the planets that surround dwarf star TRAPPIST-1 – highlighting that most planets near earth’s size are likely to be rocky. “It will be really fascinating when we get to dive into the atmosphere of each of these planets and see how different or similar they are," said postdoc Julien de Wit.
