Pulsar Image

Description: Artist's rendering of a pulsar - a rapidly rotating neutron star that emits a beam of radiation that passes the Earth once every rotation. This results in the appearance of a pulsating star, hence the term pulsar.

Gravitational Wave Background

Description: Artist's rendering of black hole binaries emitting gravitational waves. As the waves overlap, they produce a background of gravitational waves that creates a distinctive correlation pattern in the timing of pulses coming from pairs of pulsars.
