This Telescope Will Probe Alien Atmospheres

A group of astronomers now hope to fill this gap in our knowledge. They are raising money for a nearly $4 million project called the Polarized Light from Atmospheres of
Nearby ExtraTerrestrial Systems (PLANETS) telescope. If funding, site approvals and construction all line up, they hope to have the 1.85-meter telescope ready by mid-2018.
The ultimate goal is to create a $600-million Colossus telescope with 60 independent off-axis 8 meter telescopes, all in a single structure, but that's down the road.
First things first: the PLANETS telescope has less than a million dollars of funding to go before construction can begin.
