We have no idea what dark matter is, but there's one thing that we are pretty sure of: some of this mystery stuff is smacking into you once every 10 seconds. You may now start to panic.
 
Astronomers have been studying the results of the biggest survey ever conducted by the Hubble space telescope with an international team of scientists, led by Tim Schrabback of the Leiden Observatory and Ludovic Van Waerbeke of the University of British...
