The Seventh World of Trappist-1
Explanation: Seven worlds orbit the ultracool dwarf star TRAPPIST-1. A mere 40
light-years away, many of the exoplanets were discovered in 2016 using the
Transiting Planets and Planetesimals Small Telescope (TRAPPIST) located in the
Atlas Mountains of
Morocco, and later confirmed with telescope including NASA's
Spitzer Space Telescope. The
TRAPPIST-1 planets are likely all rocky and similar in size to Earth, and so compose one of the largest
treasure troves of terrestrial planets ever detected around a single star. Because they orbit very close to their faint, tiny star they could also have regions where surface temperatures
allow for the presence of ice or even liquid water, a key ingredient for
life.
Their tantalizing proximity to Earth makes them
prime candidates for future telescopic explorations of the atmospheres of
potentially habitable planets. All seven
exoplanets appear in the featured illustration, which imagines a view from the most distant known world of this system,
TRAPPIST-1h, as having a rocky landscape covered in ice. Meanwhile, in the imagined background, one of the system's inner planets crosses in front of the dim, orange, nearly
Jupiter-sized parent star.
