A new study by MIT researchers provides evidence that the first life on Earth likely came from shallow ponds, not oceans, reports the Xinhua news agency. The researchers found that primitive ponds that were about “10 centimeters deep had higher concentrations of nitrogen, a key ingredient for life on Earth.”
LiveScience reporter Stephanie Pappas writes that a new study by MIT researchers finds that massive tectonic collisions in the tropics may have led to the last three ice ages on Earth. “This could provide a simple tectonic process that explains how Earth goes in and out of glacial periods,” explains Prof. Oliver Jagoutz.
Nature reporter Alexandra Witze highlights the TESS satellite’s success in uncovering new exoplanets outside our solar system. Senior research scientist George Ricker feels, “TESS works better than team members had dared to dream,” Witze writes, adding that “its four cameras can see objects 20% fainter, and focus more sharply, than originally expected.”
NASA’s MIT-led TESS mission has discovered a new exoplanet orbiting a star 53 light years from Earth, reports Mike Wall for Space.com. The “sub-Neptune” planet is “about three times bigger than Earth, which means it's likely gaseous rather than rocky,” writes Wall.
CNN reporter Ashley Strickland writes that NASA’s planet-hunting satellite TESS has discovered another exoplanet 53 light years away. Strickland explains that the exoplanet orbits “a bright neighboring star in the Reticulum constellation, with a 36-day orbit and a surface temperature of 300 degrees Fahrenheit.”
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.”
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.”
Fast Company reporter Melissa Locker writes that a study by MIT researchers examines the feasibility of harnessing laser technology to try to attract the attention of aliens. Locker explains that the researchers found that if contact was made, “lasers could potentially be used to send Morse code-like message via light pulses.”
Writing for Popular Mechanics, David Grossman highlights a feasibility study by MIT researchers that provides evidence that lasers could be used to try to locate aliens. Grossman explains that the light would be targeted toward “areas like Proxima Centauri, the closest star to Earth, and TRAPPIST-1, a star around 40 light-years away with seven exoplanets in orbit.”
USA Today reporter Brett Molina writes that MIT researchers have found laser technology could be used to attract the attention of aliens. The researchers found “creating a 1- to 2-megawatt laser focused through a telescope aimed toward space could produce a light strong enough to stand out from the energy produced by 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.”
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!’”
