A NASA spacecraft that intentionally crashed into an asteroid last week kicked up so much debris that a dusty trail now extends 6,000 miles into space from the impact site, according to observations by astronomers. 

The shimmering outline of the trail appears in a stunning new image from Chile’s Southern Astrophysical Research (SOAR) telescope, released on Monday by the National Science Foundation's NOIRLab, which operates SOAR.
