- What’s the missing link between stars and planets? - All About SpaceWith masses that range from just a few times larger than our solar system’s gas giant Jupiter, to around 75 times its size, brown dwarfs are often considered to be the missing link between gas giant planets and red dwarf stars – the smallest known ‘true stars’.
- Life looks ‘more likely’ around Alpha Centauri - All About SpaceAlpha B is smaller and dimmer than the Sun, but still relatively similar. The third member, Alpha Centauri C (also known as Proxima), is an incredibly smaller red dwarf star that travels around the AB pair in an orbit that is 10 thousand times greater than the Sun-Earth distance.
- Two of the TRAPPIST-1 planets are most likely to harbour lifeThe seven planets that orbit the red dwarf star are given a designated letter, ranging from b to h, with b being the closest planet to the star and h being the furthest. Vera Dobos, assistant research fellow at Konkoly Observatory, Hungary, shows that the planets TRAPPIST-1d and e are the most likely planets to be habitable.
- Hubble studies atmospheres of Earth-like exoplanets for the first timeTRAPPIST-1b completes a circuit around its red dwarf star in 1.5 days and TRAPPIST-1c in 2.4 days. The planets are between 20 and 100 times closer to their star than Earth is to the Sun. Because their star is so much fainter than our Sun, researchers think that at least one of the planets, and possibly both, may be within the star’s habitable ...
