Here’s a Clever Idea, Looking for the Shadows of Trees On Exoplanets to Detect Multicellular Life

That’s the kind of headline that can leave us scratching our heads. How can you see tree shadows on other worlds, when those planets are tens or hundreds of light years—or even further—away. As it turns out, there might be a way to do it. One team of researchers thinks that the idea could potentially …

Highest Resolution Mosaic Image of the Surface of Bennu

NASA and the University of Arizona have released a stunning new global map of asteroid Bennu. At 2 inches (5 cm) per pixel, this is the highest-resolution global map of any planetary body. This hi-res map will help guide the OSIRIS-REx spacecraft to the surface of the asteroid to collect a sample, currently scheduled for …

These are the Boulders OSIRIS-REx is Going to Use to Navigate Down to the Surface of Bennu

Meet OSIRIS-REx’s “Guide Boulders.” When the NASA spacecraft first arrived at asteroid Bennu over a year ago, the surface of the asteroid was much different than expected. Instead of a surface with large, smooth areas, nearly the entire surface is covered in boulders. That meant that NASA had to do a re-think of the sampling …

Asteroid Bennu is Getting Some Official Names for its Surface Features

Late last summer, NASA and the International Astronomical Union’s Working Group for Planetary System Nomenclature (a.k.a WGPSN) approved the naming convention for features on Bennu, the asteroid currently being orbited and studied by the OSIRIS-Rex spacecraft. The naming theme chosen was “birds and bird-like creatures in mythology.” The first twelve features thusly named have now …
