  • Mars may be smaller than Venus and Earth because, in the early solar system, much mass was directed away from its orbit by the gas and ice giants. Universe Today reports.
  • Gizmodo notes the discovery of another Kuiper Belt object with a strange orbit pointing to the possibility of Planet Nine.
  • The Gaia satellite has turned up evidence for nearly fourteen thousand white dwarfs within 100 parsecs of our sun, a huge increase in numbers. Universe Today reports.
  • The work and the thinking that went into proving the idea of thousands of black holes in close orbit of Sagittarius A* at the heart of our galaxy is impressive. Universe Today reports.
