Explanation:
Three new found worlds
orbit the ultracool dwarf star
TRAPPIST-1, a mere
40 light-years away.
Their transits were first detected by the
Belgian robotic
TRAnsiting Planets and Planetesimals
Small Telescope,
TRAPPIST, at ESO's La Silla Observatory in Chile.
The newly discovered
exoplanets are all similar in size to Earth.
Because they orbit very close to their faint, tiny star
they could also have regions where surface temperatures
allow for the presence
of liquid water, a key ingredient for life.
Their tantalizing proximity
to Earth makes them prime candidates for future
telescopic explorations of the atmospheres of
these potentially habitable planets.
All three worlds appear in
this artist's vision,
an imagined scene near the horizon of the system's outermost planet.
Of course, the inner planet is transiting
the dim, red, nearly Jupiter-sized parent star.
