Three newly discovered ultra-faint dwarf galaxies could offer clues to the conditions in the early universe and to the nature of dark matter.
When solar winds bombard Earth's magnetosphere, they create waves that shouldn't be able to traverse a turbulent region called the shock. New research demonstrates how this appears to happen.
The face of the moon will be half-illuminated once again on Saturday (Jan. 14) as the moon enters its last quarter phase heading to the next new moon and the start of the next lunar cycle.
