The Hubble and Webb space telescopes both observed the DART asteroid impact, and both saw distinct “streamers” in the ejecta. Which seems rather odd given that the asteroid appears to have been a loosely-assembled gravel pile, with nothing holding the ejected particles together… no surface tension, no magnetic fields, not even any appreciable gravity.
