TRAPPIST-1: An Alien Solar System
On May 2, 2016, scientists announced the discovery of TRAPPIST-1, an alien solar system 40 light-years from Earth with a tiny, ultracool dwarf star and three small exoplanets that just might be habitable. See imaginary views of the TRAPPIST-1 system in this slideshow. HERE: An artist's view of the TRAPPIST-1 star system as seen from near one of the three alien planets circling their dim parent star.

One Star, Three Worlds
This artist's illustration depicts an imagined view from the surface of one of the three newfound TRAPPIST-1 alien planets. The planets have sizes and temperatures similar to those of Venus and Earth, making them the best targets yet for life beyond our solar system, scientists say.

TRAPPIST-1 vs. The Sun
This image shows a size comparison between Earth's sun (left) and the tiny, ultracool dwarf star TRAPPIST-1 located 40 light-years from Earth. Read our full story on the TRAPPIST-1 planets.
Where Is TRAPPIST-1
The TRAPPIST-1 alien planets and star system are located 40 light-years from Earth in the direction of the constellation Aquarius. Read our full story on the TRAPPIST-1 planets.
La Silla: TRAPPIST's Home
The TRAPPIST-1 star system and planets were discovered by scientists using the TRAPPIST (short for TRAnsiting Planets and PlanetesImals Small Telescope) instrument at the La Silla Observatory in Chile, which is operated by the European Southern Observatory.

How Habitable Zones Around Stars Work (Infographics)
The habitable zone around stars is a so-called Goldilocks' zone where conditions are just right for liquid water. See how habitable zones work in this Space.com infographic.
