Want to watch some astronomers blow up the top of a mountain? You can!
Seriously, construction crews will in June begin blasting to prepare this mountain top in Chile for the European Extremely Large Telescope (E-ELT), a gigantic optical telescope that will have a primary mirror 39 meters or 128 feet across and is scheduled for completion sometime in the next decade. To mark the event they will be providing a live stream for everyone worldwide to watch.
