Teleios, a highly spherical supernova remnant in our galaxy, presents astronomers with a unique opportunity to understand supernova explosions. Its shape suggests it has not been significantly affected by its surroundings, which is rare. This specific remnant is believed to have originated from a type Ia supernova, an event occurring once every 500 years, where a white dwarf star explodes after siphoning materials from a companion star. Understanding Teleios could provide insights into some of the universe's most energetic occurrences.
"The shape indicates Teleios has remained relatively untouched by its environment," said lead author Miroslav Filipovic. "This presents us with an opportunity to make inferences about the initial supernova explosion."
The astronomers believe that Teleios is the result of a rare type of explosion...called a type Ia supernova...that occurs in binary star systems.
