I’m hopeful that other planets around M dwarfs could keep their atmospheres, says Laura Kreidberg, a researcher at the Harvard and Smithsonian Center for Astrophysics, about a new study using data from NASA’s Spitzer Space Telescope provides a rare glimpse of conditions on the surface of a rocky planet, LHS 3844b, located 48.6 light-years from Earth. “The terrestrial planets in our solar system are enormously diverse, and I expect the same will be true for exoplanet systems.”
The Transiting Exoplanet Survey Satellite (TESS) captured this strip of stars and galaxies in the southern sky all the way through one 30-minute duration on Tuesday, Aug. 7, 2018. Created through combining the view from all four of its cameras, here is TESS’ “crack of dawn,” from the 1st staring at sector that can be used for making a choice on planets around other stars. Notable features in this swath of the southern sky come with the Large and Small Magellanic Clouds and a globular cluster known as NGC 104, also known as 47 Tucanae. The brightest stars within the image, Beta Gruis and R Doradus, saturated an entire column of camera detector pixels at the satellite’s moment and fourth cameras.
