Query: SPECULOOS: a network of robotic telescopes to hunt for terrestrial
  planets around the nearest ultracool dwarfs   We present here SPECULOOS, a new exoplanet transit search based on a network
of 1m-class robotic telescopes targeting the $\sim$1200 ultracool (spectral
type M7 and later) dwarfs bright enough in the infrared ($K$-mag $\leq 12.5$)
to possibly enable the atmospheric characterization of temperate terrestrial
planets with next-generation facilities like the $\textit{James Webb Space
Telescope}$. The ultimate goals of the project are to reveal the frequency of
temperate terrestrial planets around the lowest-mass stars and brown dwarfs, to
probe the diversity of their bulk compositions, atmospheres and surface
conditions, and to assess their potential habitability.
