In new research, scientists examined the populations of stars observed by the Kepler and K2 missions and found that the solar systems were different depending on the type of star involved. Plus, CHIME results, a brown dwarf’s atmosphere, a stream of stars in the Milky Way, and an interview with PSI’s Dr. Candice Hansen about the recent Ganymede flyby of NASA’s Juno spacecraft.
After a brief vacation, Rocket Roundup is back with six launches, including three from SpaceX, another OneWeb, and two Chinese launches, including a supply mission to their new space station. Plus, this week in rocket history, we look back at an important mission to Venus, Venera 9.
The most precise measurements of the universe’s composition and growth have been reported in almost thirty new papers based on Dark Energy Survey observations of 229 million galaxies and covering one-eighth of the sky.
