NASA Telescope Captures Epic Collision Between DART Probe and Asteroid Dimorphos - CNet

Panzer found a post at CNet by Jackson Ryan about NASA's DART probe which was launched in November of last year.  The DART probe was crashed into the asteroid Dimorphos as part of a NASA experiment. If the experiment is successful, Dimorphos will have been pushed slightly out of its orbit. NASA won't know until next year if it was successful.
  Nap time.
Then, if at some time in the future the Earth is threatened by a collision with a space rock/debris/errant asteroid, such a probe can be used to change the object's course.

Note: There is more than one post at the site about the DART probe.
