Neutron Star :CP 1919 aka PSR B1919+21 and PSR J1921+2153
Neutron Stars are the densest objects in the Universe, formed from a giant star which has collapsed to a sphere that could typically fit between Kensington and Tower Bridge. It's so dense that the electrons and protons are combined into neutrons - as if the whole star were one big atomic nucleus - so one teaspoon of a neutron star would weigh about the same as all humans on Earth put together... But that's not all; neutron stars spin fast: CP 1919 spins 1.3 times per second, but others like PSR J1748-2446ad rotate much faster at 716 times each and every second. Unimaginable density and mind boggling speeds create all manner of phenomena including high intensity magnetic fields and intense beams of radio waves, which we detect as pulses (like a lighthouse) here on Earth. It was such a regular pulse that gave rise to the name 'Pulsar' as discovered by Jocelyn Bell Burnell in 1967. Having read the book "Neutron Stars: The Quest to Understand the Zombies of the Cosmos" by Katia Moskvitch, I was inspired to produce this handmade copper plate mezzotint print on Fabriano Tiepolo paper with dimensions 28 x 38 cms.
