Researchers are suggesting a new way to use them to measure the expansion of the universe directly. They propose a method called intensity correlation speckles to measure the difference between the redshift - in which light stretches as it travels through an expanding universe, causing its wavelength to elongate - in two paths of light from the same quasar.

In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses.

A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means that the amount of gas a core accretes as it develops, and not the initial mass of the core, is the key factor in deciding the final mass of the produced star.
