NASA’s MIT-led TESS mission has discovered a new exoplanet that is about three times the size of Earth, reports Dennis Overbye for The New York Times. “There was quite some detective work involved, and the right people were there at the right time,” explains postdoctoral fellow Diana Dragomir. “But we were lucky, and we caught the signals, and they were really clear.”
Verge reporter Loren Grush writes that NASA’s MIT-led TESS mission has discovered a third exoplanet. “The important thing about this system that’s especially unique is it’s near to us,” says postdoc Diana Dragomir. “What that means simply is we can study this system in detail. We can measure the mass of the planet and measure things about the star.”
Prof. Richard Binzel speaks with Living Lab Radio about NASA’s New Horizons mission, which captured pictures of the most distant object ever explored by a spacecraft. “We have an incredibly healthy spacecraft,” says Binzel. “We’ve shown incredible capability of these instruments, and with a little bit of luck we'll find another object that's up on the path ahead and we'll just keep exploring.”
TechCrunch reporter Devin Coldewey highlights how MIT researchers have found that tiny satellites, called CubeSats, equipped with lasers could help keep telescopes on track while they are gathering information in space. The light emitted from the lasers could allow satellites “to calculate their position and the minute changes to their imaging apparatus caused by heat and radiation.”
Prof. Maria Zuber, MIT’s vice president for research, speaks with The Washington Post about the significance of China successfully landing a spacecraft, called Chang’e 4, on the far side of the moon. “Certainly there will be some great new science,” Zuber said. “But I would say the landing of Chang’e 4 is a teaser for what comes next.”
NASA’s Voyager 2 probe has entered interstellar space, reports CBS News. "Working on Voyager makes me feel like an explorer, because everything we're seeing is new," says John Richardson, principal investigator for the plasma science experiment onboard the spacecraft.
Researchers from the LIGO and Virgo Scientific Collaborations have detected four new black hole collisions, including the largest black hole merger detected, reports Ryan Mandelbaum for Gizmodo. Researchers have begun cataloguing “black hole collisions to tell the broader story about how often these massive crashes occur and what causes them.”
BBC News reporter Jonathan Amos writes that LIGO (operated by MIT and Caltech) and Virgo researchers have detected gravitational waves emanating from the largest black hole merger ever detected. Amos notes the discovery was announced by the collaboration as part of an “expanded catalogue” of detections that “tells us something about the probable future successes of the laser laboratories.”
Graduate student James Clark speaks with Boston Globe reporter Andres Picon about his study that provides evidence laser technology could be used to attract aliens. “A laser produces all of its power in one wavelength,” explains Clark, “so the way that it’s detectable is not that it’s more powerful than the sun, but that it’s very distinct from the sun.”
UPI reporter Tauren Dyson writes that a new feasibility study by MIT researchers shows that existing laser technology could be used to create a beacon light that could attract attention from as far as 20,000 light years away.
MIT researchers have found that laser technology could be used to attract attention from alien astronomers, reports Becky Ferreira for Motherboard. The researchers found that amplifying an infrared laser could “produce a signal that would outshine the Sun’s infrared emissions tenfold, an anomaly that would stand out to a smart species observing our solar system from a distant exoplanet.”
Prof. Marcia Bartusiak speaks with Radio Boston’s Evan Horowitz about her book, “Dispatches from Planet 3.” Bartusiak explains that she was inspired to “take a new exciting finding and provide the backstory. All of these essays are taking something new - a new idea, a new discovery - and showing that it had an origin or a seed in the past.”
Two months after its launch, the TESS satellite has already identified two new exoplanet candidates, reports Mary Beth Griggs for Popular Science. “The team is excited about what TESS might discover next,” explains Prof. Sara Seager, who is serving as the deputy science director for the mission.
New Scientist reporter Will Gater writes that the TESS satellite has found its first two exoplanets. “This is one of the first objects we looked at,” says MIT postdoctoral fellow Chelsea Huang of the discovery of an exoplanet about 60 light years away. “We were immediately saying ‘hey this is too good to be true!’”
New York Times reporter Dennis Overbye writes about how the TESS satellite has already identified at least 73 stars that might have exoplanets. “TESS is doing great,” says George Ricker, a senior research scientist at MIT who is leading the TESS mission. Ricker adds that the satellite is, “all that we could have wished for!”
