Universe Today 22 Jun 2020, 15:36 UTC Several moons in our Solar System are “ocean worlds”, believed to have abundant liquid water in their interiors. What about in other planetary systems: how common are these ocean worlds in our galaxy?
Bad Astronomy 19 Jun 2020, 15:06 UTC Hubble has captured stunning images of two planetary nebulae: the gaseous and dusty winds blown into space when a Sun-like star dies. These wondrous shapes can reveal more information about the star they came from.
Astrobiology Magazine 18 Jun 2020, 15:32 UTC There may be as many as one Earth-like planet for every five Sun-like stars in the Milky way Galaxy, according to new estimates by University of British Columbia astronomers using data from NASA’s Kepler mission.
SciTech Daily 18 Jun 2020, 10:30 UTC A team of astronomers, including researchers at MIT, has picked up on a curious, repeating rhythm of fast radio bursts emanating from an unknown source outside our galaxy, 500 million light years away.
Centauri Dreams 17 Jun 2020, 16:28 UTC 38 K, which translates to -235 Celsius or -390 Fahrenheit, is cold enough to allow atmospheric nitrogen to condense as surface frost, which appears to be what is happening on Neptune’s large moon Triton. This is an intriguing place, with pinkish deposits at the enormous south polar cap that are thought to contain methane ice — the color would derive from reactions with sunlight to form a variety of pink or red compounds. Moreover, there are geyser-like plumes here that leave dark streaks over the ices, some of them active when Voyager 2 flew past.
