Several Kepler Planets Turn Out to be Small Stars

Several Kepler Planets Turn Out to be Small Stars

Using updated stellar measurements based on new data from the Gaia mission, three (and possibly four) Kepler exoplanets are actually small stars, but it’s unlikely new calculations will reveal many more such issues. Plus, Ingenuity, astronauts, permafrost, and This Week in Rocket History, we look back at STS-3 and the first use of the Canadarm.

Rogue Planets Found Near Milky Way’s Core

Rogue Planets Found Near Milky Way’s Core

Using data collected by NASA’s Kepler Space Telescope, scientists have found four free-floating, or rogue, planets near the core of the Milky Way. These planets formed in discs in other planetary systems and were thrown out by gravitational interactions with larger planets. Plus, the early solar system, including ancient Earth, Jupiter’s chemistry, and Mercury’s core.

Solar Systems Vary From Star Type to Star Type

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.
