3-D climate modeling could fine-tune the search for faraway signs of alien life
An artist’s conception shows a hypothetical planet with two moons orbiting within the habitable zone of an M-dwarf star. (NASA / Harvard-Smithsonian Center for Astrophysics Illustration / D. Aguilar) Astronomers have identified thousands of stars that have planets, and that number could mushroom even faster when waves of next-generation telescopes come online. But where are…

Hubble keeps hope alive for water on potentially habitable TRAPPIST-1 planets
This artist’s impression shows how the surface of a planet orbiting a red dwarf star may appear. The planet is in the habitable zone, so liquid water exists. (CFA Illustration / M. Weiss) Do some of the Earth-sized planets around a dwarf star called TRAPPIST-1, just 40 light-years away, have liquid water? Newly reported findings…

Astronomers use the music of the spheres to track TRAPPIST-1’s seventh planet
An artist’s conception shows the planet TRAPPIST-1h. (NASA / JPL-Caltech) An international research team led by a University of Washington astronomer has worked out the intricate dance of seven planets circling an ultracool dwarf star known as TRAPPIST-1, nailing down the coordinates of the outermost world in the process. The astronomers found that all seven…

Star found with record seven Earth-size planets
STORY WRITTEN FOR CBS NEWS & USED WITH PERMISSION This artist’s concept shows what each of the TRAPPIST-1 planets may look like, based on available data about their sizes, masses and orbital distances.Credits: NASA/JPL-Caltech Astronomers have discovered seven roughly Earth-size planets very close to a cool dwarf star some 39 light years from Earth, including three orbiting…

Looking for life: Scientists find 7 possibly Earthlike planets orbiting ultracool star
A diagram shows seven exoplanets orbiting an ultracool dwarf star known as TRAPPIST-1. If the planets were transported to our own solar system, they’d all lie within Mercury’s orbit. (ESO Illustration) A second look at an exoplanet system 40 light-years from Earth has brought a bonanza for astronomers: not two, not three, but seven alien worlds…

NASA keeps its eye on a trio of potentially habitable planets just 40 light-years away
An artist’s impression shows an imagined view from the surface one of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth. (Credit: ESO) Three potentially habitable and definitely weird planets have been detected orbiting an ultracool dwarf star that’s 40 light-years away from Earth. They’re too far to visit anytime soon,…
