WHAT do you get when a star the size of a small city collapses?
The answer is a whopping 40 trillion mile jet of matter and antimatter.
NASA spotted the “tiny” spinning pulsar a staggering 1,600 light-years from Earth.
The superdense star — dubbed J2030 — spins at a dizzying three times per second and rockets through space at about a million miles per hour.
Astronomers actually spotted the massive jet in 2020.
But it’s so long that their high-tech kit couldn’t see the ends.
It was only when experts decided to give the Chandra X-ray Observatory another try were they stunned to discover that it was three times larger than predicted.
“It’s amazing that a pulsar just 10 miles across can create a structure so big we can see it thousands of light-years away,” said Martjin de Vries of Stanford University.
“If the filament stretched from New York to Los Angeles at the same relative size, the pulsar would be about 100 times smaller than the smallest object visible to the naked eye.”
Experts believe the beam could help them finally understand a question that has puzzled them for centuries.
Why is the Milky Way filled with so many positrons, a kind of antimatter counterpart of electrons?
“This probably triggered a particle leak,” said Roger Romani, also of Stanford University.
“The pulsar wind’s magnetic field combined with the interstellar magnetic field, and the high-energy electrons and positrons spurted out through a nozzle formed by coupling.”
Their research is published in the Astrophysical Journal.
