5 years after New Horizons flyby, 10 cool things about Pluto

Here are 10 of the coolest, weirdest and most unexpected findings about the Pluto system scientists have learned thanks to the New Horizons spacecraft’s flyby of the distant world in 2015. Source: https://earthsky.org/space/new-horizons-flyby-10-cool-things-about-pluto…

Super-Earths discovered orbiting nearby red dwarf

The nearest exoplanets to us provide the best opportunities for detailed study, including searching for evidence of life outside the solar system. In research led by the University of Göttingen, the RedDots team of astronomers has detected a system of super-Earth planets orbiting the nearby star Gliese 887, the brightest red dwarf star in the sky. Super-Earths are planets which have…

Did ancient Mars have rings?
