This view of asteroid Bennu ejecting particles from its surface on January 6 was created by combining two images taken by the NavCam 1 imager onboard NASA’s OSIRIS-REx spacecraft: a short exposure image (1.4 ms), which shows the asteroid clearly, and a long exposure image (5 sec), which shows the particles clearly.

The OSIRIS-REx science team has developed three possible explanations for the particles the asteroid Bennu is discharging into space.
One of the greatest threats from the sun — to astronauts and the satellites that provide GPS maps, cell phone service, and internet access — are high-energy particles that erupt from the sun in bursts. (Artist impression: NASA/Princeton)
