Dark matter is a hypothetical form of matter that is believed to make up more than 90% of the mass of the universe but is not readily visible because it neither emits nor absorbs light. Its existence could explain gravitational anomalies observed in the motion and distribution of galaxies. In 1993, astronomers identified part of the dark matter in the form of stray planets and brown dwarfs, and, possibly, stars that have failed to ignite. What acronym is used to refer to this hot, dark matter?

How many ships set sail with his second expedition?
