While we space geeks are lucky enough to watch rocket launches regularly, it’s not often we get to see a mountain top being blown off for the sake of astronomy!

Tomorrow, the European Southern Observatory plans an event centered on a blast on Cerro Armazones, a 3,060-meter (10,000-foot) mountain in Chile’s Atacama Desert. The goal is to make way for construction of the European Extremely Large Telescope, which as its name implies will be a monster of an observatory. Read below for details on how to watch live.

“The E-ELT will tackle the biggest scientific challenges of our time, and aim for a number of notable firsts, including tracking down Earth-like planets around other stars in the ‘habitable zones’ where life could exist — one of the Holy Grails of modern observational astronomy,” ESO states on its page about the 39-meter (128-foot) optical/near-infrared telescope.

“It will also perform ‘stellar archaeology’ in nearby galaxies, as well as make fundamental contributions to cosmology by measuring the properties of the first stars and galaxies and probing the nature of dark matter and dark energy.”

We’re sure astronomers can hardly wait for operations to start in the next decade or so. ESO will livetweet the event (also follow the hashtag #EELTblast, where you can ask questions) and watch the entire event live tomorrow here, starting around 12:30 p.m. EDT (4:30 p.m. UTC).

In related news, the last of the Atacama Large Millimeter/submillimeter Array’s (ALMA’s) 66 antennas recently arrived at the ALMA site, which is 5,000 meters (16,400 feet) high on the Chajnantor Plateau in the Atacama Desert of northern Chile. This ESO telescope was officially inaugurated last year.
