Cerro Seco National Observatory sits on a mountaintop high above the empty desert of southern Arizona. You arrive for a one-week observing run expecting to meet your research advisor and a team of technicians, but instead you find the observatory empty. Systems are shut down, doors chained, and networks offline.

Bring the observatory back online to complete your research. Operate the telescope, catalog objects in the sky, and restore the observatory to working order.

As the nights pass, the observatory grows more capable, seeing more clearly and into new spectra. The catalogue of stars grows.

But so does the list of phenomena you can't explain.

Features

• Operate a research telescope through the night, juggling power, data storage, and optics calibration while pushing the equipment harder each night

• Scan and identify stars, distant galaxies, and objects that don't fit any known category

• Uncover what the previous team found - and why they left without a word
