Do red dwarfs or sunlike stars have more Earth-sized worlds?
Earth is our only example of a habitable planet, so it makes sense to search for Earth-size worlds when we're hunting for potentially-habitable exoplanets. When astronomers found seven of them orbiting a red dwarf star in the TRAPPIST-1 system, peopl.....»»
Two Neptune-sized exoplanets discovered with TESS
An international team of astronomers reports the detection of two new exoplanets orbiting a bright star known as TOI-5126, using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien worlds are similar in size to the solar system's.....»»
