Astronomers using the NASA/ESA Hubble Space Telescope have conducted the first search for atmospheres around temperate, Earth-sized planets beyond our solar system. They found indications that increase the chances of habitability on two exoplanets known as TRAPPIST-1b and TRAPPIST-1c orbiting a red dwarf star approximately 40 light-years away.
Astronomers have discovered three planets orbiting an ultra-cool dwarf star just 40 light-years from Earth. These worlds have sizes and temperatures similar to those of Venus and Earth and are the best targets found so far for the search for life outside the solar system. They are the first planets ever discovered around such a tiny and dim star.
Astronomers have observed the extreme temperature variations of HD 80606 b, a Jupiter-sized exoplanet with a highly eccentric, comet-like orbit that brings it scorchingly close to its parent star every 111 days. The researchers also calculated the planet’s rotation rate — the first exoplanet rotation rate ever obtained.
