Researchers Trace Dust Grain's Journey Through Newborn Solar System

Artist’s illustration of the early solar system, at a time when no planets had formed yet. A swirling cloud of gas and dust surrounded the young sun. The cutaway through this so-called protoplanetary disk shows its three-dimensional structure.

UArizona to Lead Mission to Discover Potentially Dangerous Asteroids

The NEO Surveyor infrared space telescope is optimized for finding, tracking and characterizing potentially hazardous asteroids and comets. The spacecraft’s sunshade (silver vertical part) blocks out sunlight and keeps the telescope shielded so that it can search for the faint heat signatures from Earth-approaching objects. The asteroids will appear as strings of dots (color-coded red in the background image) that will stand out against the background stars (color-coded blue). NASA/JPL
