A new effort to detect extraterrestrial life will listen for radio pulses coming from the galactic nucleus. Pulsars, which are stars that naturally emit narrow-frequency pulses, are also intentionally used by humans in technology like radar.
These pulses are a useful means of communication over great distances and a desirable target to listen for when looking for extraterrestrial civilisations because they stand out against the ambient radio noise of space.
A recent study that was released on May 30 in The Astronomical Journal by researchers described their approach to looking for alien life.
