And while we're on the topic of #Pulsars, an exciting thing happened in the last few days ... the relatively nearby #VelaPulsar happened to glitch again!

Vela is known to glitch every 2.5-3 years, so let's dig in with a short thread on why this is exciting.

First of all, here's the @astronomerstel notification: astronomerstelegram.org/?read=14806

But I heard about it through Pro-Am radio astronomer (and friend!) @hawk_RAO who picked it up early!

Steve runs the Hawkesbury Radio Observatory just near Sydney.

So let us look at some #space and ground-based telescopes that give us information about #pulsars via #multiwavelengthastronomy
Most gamma rays coming from space are absorbed by the Earth's atmosphere, so the telescopes are space based. The @fermitelescope & Integral missions have discovered many gamma-ray pulsars
In addition to the X-ray telescopes such as @chandraxray & @NASANuSTAR, the recently launched #NICER mission will help us probe the pulsar interior (I will explain this tomorrow)

In fact, the sound of the pulsars sound like beats ๐Ÿ˜€๐ŸŽผ Listen to the Crab pulsar ๐Ÿ‘‡
