Astronomers Discover Teleios, A Supernova Remnant With Perfect Symmetry
Imagine a star that blew up, leaving behind a cloud of gas and dust.
Scientists found one of these clouds, called Teleios, and it's special because it's almost perfectly round, which is unusual.
They found it using special telescopes that see radio waves.
The cloud is really far away, so it's hard to know exactly how big it is.
Scientists think it might have come from a certain type of exploding star.
They plan to study Teleios more closely to learn more about how stars explode and what happens afterward.
This could teach us more about how the universe works.
Astronomers have discovered a supernova remnant with an unusual symmetrical structure, named Teleios.
The remnant, officially designated G305.4–2.2, was identified using radio-continuum images from the Australian Square Kilometre Array Pathfinder (ASKAP).
Teleios is located approximately 7,170 or 25,100 light years away, with a diameter of 45.6 or 156.5 light years, respectively.
Extended radio emission suggests interaction with the local interstellar medium.
Researchers propose Teleios likely originated from a Type Ia supernova.
