If the planetary-mass objects that wander our galaxy without a host star have Io- or Titan-size exomoons, future observatories like the James Webb Space Telescope should be capable of detecting more than half of them.

Analysis of 30 extremely low-mass dwarf galaxies suggests that star formation in these gas-poor galaxies follows the same trends as higher-mass galaxies.

Mapping observations of dense cores of molecular clouds on the cusp of star formation reveal different that some small molecules are evenly dispersed while others are present in a clumpy structure.
