planets around TRAPPIST - 1.

the planets around TRAPPIST - 1, named after the telescope.
It's been less than a year since astronomers detected seven
planets around TRAPPIST - 1, a remarkable star system located 39 light years from Earth.
Vincent Bourrier at the University of Geneva in Switzerland and his team tracked the UV radiation that reaches
the planets around TRAPPIST - 1.
But, for a handful of
the planets around TRAPPIST - 1, there's not enough UV radiation to destroy the water molecules.

Astronomers using the
TRAPPIST - South telescope at ESO's La Silla Observatory, the Very Large Telescope (VLT) at Paranal and the NASA Spitzer Space Telescope, as well as other telescopes

The astronomers carefully measured how long it takes for each
planet in the system to complete one orbit

Because the
planets are in such close orbits
around TRAPPIST - 1, some or all of them may be tidally locked, which means that they always present the same side to the star and the opposite side away from the star.
