Very cool exoplanet news, literally: Two super-Earth planets have been found around a red dwarf star, and one of them is at the right distance from its star to — possibly —be reasonably temperate .  The star is called LP 890-9 — the LP stands for Luyten/Palomar; using the big telescope astronomer Willem Luyten mapped and catalogued thousands of nearby stars. LP 890-9 is a very tiny star, a red dwarf with only 1/9 th of the Sun’s mass and 1/6 th its diameter. Its temperature is only 2,580°C (4,670°F), much cooler than the Sun, and it puts out an incredibly feeble 0.1% as much light as the Sun. At 100 light-years away, relatively close, it’s so faint you need a big ‘scope to see it [ link to paper ]. The first planet, LP 890-9b, was discovered by TESS, the Transiting Exoplanet Survey Satellite, which scans the entire sky looking at thousands of stars.…
