SPECULOOS Project Makes Its First Observations
The SPECULOOS Southern Observatory (SSO) has been successfully installed at the Paranal Observatory and has obtained its first engineering and calibration images — a process known as first light. After finishing this commissioning phase, this new array of planet-hunting telescopes will begin scientific operations, starting in earnest in January 2019.
SSO is the core facility of a new exoplanet-hunting project called Search for habitable Planets EClipsing ULtra-cOOl Stars (SPECULOOS), and consists of four telescopes equipped with 1-metre primary mirrors. The telescopes — named Io, Europa, Ganymede and Callisto after the four Galilean moons of Jupiter — will enjoy pristine observing conditions at the Paranal site, which is also home to ESO's flagship Very Large Telescope (VLT). Paranal provides a near-perfect site for astronomy, with dark skies and a stable, arid climate.
These telescopes have a momentous task — SPECULOOS aims to search for potentially habitable Earth-sized planets surrounding ultra-cool stars or brown dwarfs, whose planetary populations are still mostly unexplored. Only a few exoplanets have been found orbiting such stars, and even fewer lie within their parent star's habitable zone. Even though these dim stars are hard to observe, they are abundant — comprising about 15% of the stars in the nearby universe. SPECULOOS is designed to explore 1000 such stars, including the nearest, brightest, and smallest, in search of Earth-sized habitable planets.

Look around. We're obviously working hard to counter the threat by making as little use of our brains as possible.
