Pulsar in the Cosmic Disco Ball: M28's Stellar Spinner
About this Episode
This is your Astronomy Tonight podcast.
On this day in astronomical history, August 12th, we celebrate the anniversary of the discovery of the first pulsar in a globular cluster. Back in 1986, astronomers Andrew Lyne and Andrew Fruchter made a groundbreaking observation at the Arecibo Observatory in Puerto Rico. They detected a millisecond pulsar, now known as PSR B1821-24A, in the globular cluster M28.
Now, folks, let me paint you a picture of this cosmic disco ball. Imagine a dense ball of stars, hundreds of thousands of them, all packed into a space just about 100 light-years across. That's our globular cluster M28. And in the heart of this stellar mosh pit, we've got this pulsar, a city-sized neutron star, spinning faster than your blender on a smoothie-making frenzy - we're talking about 218 rotations per second!
This discovery was a game-changer, my friends. It opened up a whole new avenue for studying these dense stellar environments and the exotic objects they harbor. Pulsars in globular clusters are like cosmic timekeepers, allowing us to probe the gravitational dynamics of these stellar metropolises.
But here's the kicker - this pulsar is not just fast, it's furious! It's blasting out electromagnetic radiation like a cosmic lighthouse on steroids. If you could hear radio waves, this thing would sound like a cosmic woodpecker on a caffeine binge.
This discovery led to a pulsar bonanza in globular clusters. Today, we know of over 150 pulsars in these stellar cities, each one a testament to the extreme physics at play in our universe.
So, the next time you look up at the night sky, remember that among those twinkling points of light, there are dense clusters of stars, and within them, rapidly spinning stellar corpses, flashing their signals across the cosmos like celestial beacons.
