Results showed that in almost all cases, measured bandwidths were higher than predictions by widely used models of the galaxy, highlighting a need for updates to current ISM density models.

On November 28, 1967, astronomers found the first pulsar. A pulsar is a super-dense star that rotates super fast. As the pulsar spins, it emits two beams of light in opposite directions.
