An international team using the Gemini Planet Imager (GPI) at the Gemini South telescope in Chile has discovered a young, emerging planetary system around star HD 115600 that has remarkable similarities to our own Solar System in its infancy.
Scientists with NASA’s New Horizons mission have assembled this highest-resolution colour view of Wright Mons, one of two potential cryovolcanoes spotted on the surface of Pluto by the New Horizons spacecraft in July 2015. The feature is 90 miles across and 2.5 miles high, which would make the largest volcano in the outer solar system.
What is the origin of the large heart-shaped nitrogen glacier on Pluto revealed by NASA’s New Horizons spacecraft in 2015? Two French researchers show that Pluto’s peculiar insolation and atmosphere favour nitrogen condensation near the equator, in the lower altitude regions, leading to an accumulation of ice at the bottom of Sputnik Planum, a vast topographic basin.
