Which paragraph from the article explains why the ultracool dwarf star discovery is so significant to the search for other signs of life?
The system's host star, called TRAPPIST-1, is what is known as an ultracool dwarf. It is about
one-tenth the size of our sun and just a bit bigger than Jupiter.
Going forward, the authors plan to use even more powerful telescopes to analyze the
TRAPPIST-1 system. The Hubble Space Telescope will point its powerful lens toward the
ultracool dwarf star.
O "Systems around these tiny stars are the only places where we can detect life on an Earth-
sized exoplanet with our current technology," Gillon said in a statement. "If we want to find
life elsewhere in the Universe, this is where we should look."
O Ultracool dwarfs make up about 15 percent of the astronomical objects in our immediate
neighborhood, but until now, no one had ever discovered a planet orbiting one.
