A nugget from New Scientist a few days ago reveals a previously unnoticed asteroid impact that occurred sometime between July 2010 and May 2012. Filtering out red from the spectrum of an image of the impact crater has revealed material with blue hue, so could that be evidence of ice from beneath the surface? Another question the event raises is with regard to how many other recent events so close to home (in astronomical terms) have gone unnoticed. I wonder if it's time to get a hard hat to go with my snorkel.
