The majority
of star explosions in the cosmos are spherical, just like the stars themselves.
An intriguing new explosion has occurred 180 million light-years distant.
The
magnitude of the explosion in our current system. The size of the explosion in
our current system. Its shape is comparable to that of a highly flat disc. It
looks much flatter than anyone could have imagined.
A bright
Fast Blue Optical Transient (FBOT), which is a very uncommon type of explosion
and much less frequent than other explosions, was the explosion that was seen.
Astronomers noted the first prominent FBOT, known as "AT2018cow," in
2018.
When they
unintentionally observed a flash of polarised light, scientists made their
discovery. They were able to ascertain the polarisation of the blast using the
astronomical counterpart of polaroid sunglasses and the Liverpool Telescope,
based at Liverpool John Moores University and located on the island of La
Palma.
Scientists
observed an explosion the size of our Solar System in a galaxy 180 million
light years distant by measuring the polarization, which allowed them to
determine the shape of the explosion. In order to determine how flat the
explosion was, they were able to map its edges and recreate its 3D form using
the data.
This
flattest explosion is the most spherical ever observed in space, and a few days
after it was found, it took on the shape of a disc. It's possible that the
star's material shed just before exploding contributed to this portion of the
detonation.
"Very
little is known about FBOT explosions," said Dr. Justyn Maund, the study's
lead author from the Department of Physics and Astronomy at the University of
Sheffield. "They simply don't act like exploding stars should, they are
too bright, and they evolve too rapidly. They are already strange, and this
latest discovery makes them even stranger.
We had no
idea that blasts could be this spherical, so hopefully this new discovery will
help us understand them better. There are a few possible explanations,
including failed supernovas, in which the star's core collapses into a black
hole or neutron star, which then consumes the remainder of the star, or the
stars involved may have formed a disc just before they died.
