description PSR B1919+21 Overview
PSR B1919+21 is a radio pulsar in the constellation Vulpecula and is understood to be a rotating neutron star. Jocelyn Bell Burnell detected its regular radio pulses in 1967 while working with a radio telescope at Cambridge, and Antony Hewish led the group that reported the discovery. Originally designated LGM-1 during the investigation, the object became the first recognized radio pulsar and demonstrated that neutron stars could produce highly regular, repeating signals.

Who discovered PSR B1919+21?
Jocelyn Bell Burnell detected the regular radio pulses in 1967 while working at Cambridge's Mullard Radio Astronomy Observatory. Antony Hewish led the research group that reported the discovery. [Source](https://www.cam.ac.uk/stories/journeysofdiscovery-pulsars)
Why was PSR B1919+21 initially called LGM-1?
The first repeating signal looked so precise that Bell Burnell and colleagues briefly labeled it LGM-1, meaning Little Green Men 1. The signal was later identified as radiation from a rotating neutron star and became known as PSR B1919+21. [Source](https://www.cam.ac.uk/stories/journeysofdiscovery-pulsars)
What kind of object is PSR B1919+21?
PSR B1919+21 is a radio pulsar, meaning a rotating neutron star whose radiation beam sweeps past Earth at regular intervals. Its pulses are produced by the star's rapid rotation and strong magnetic field. [Source](https://en.wikipedia.org/wiki/PSR_B1919%2B21)
Did Jocelyn Bell Burnell receive the Nobel Prize for PSR B1919+21?
No. The 1974 Nobel Prize in Physics went to Antony Hewish and Martin Ryle for work connected with radio astronomy and pulsars, while Bell Burnell was not included among the laureates. [Source](https://www.nobelprize.org/prizes/physics/1974/summary/)
