Precise measurements reveal that the exoplanets of the system discovered by ULiège researchers have remarkably similar densities, which provides new clues about their compositions. A…
Precise measurements reveal that the exoplanets have remarkably similar densities, which provides clues about their composition. The red dwarf star PIST-1 is home to the…
Our solar system has one habitable planet — Earth. A new study shows other stars could have as many as seven Earth-like planets in the…
Astronomers using the Subaru Telescope have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star….
TRAPPIST-1 is a system of seven Earth-sized worlds orbiting an ultra-cool dwarf star about 120 light-years away. The star, and hence its system of planets,…
Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a University of…
TRAPPIST-1 is an ultra-cool red dwarf star that is slightly larger, but much more massive, than the planet Jupiter, located about 40 light-years from the…
In the year since NASA announced the seven Earth-sized planets of the TRAPPIST-1 system, scientists have been working hard to better understand these enticing worlds…
A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could…
Astronomers using NASA’s Hubble Space Telescope have conducted the first spectroscopic survey of the Earth-sized planets (d, e, f, and g) within the habitable zone…
New research reveals that several of the planets in the TRAPPIST-1 system are at the right distance from their star for liquid water to exist…
Scientists now have a good estimate for the age of the TRAPPIST-1 system, revealing that it is up to twice as old as our own…
