It hangs in the sky like a cosmic bubble, eerily round, barely glowing in the radio spectrum. Among the wreckage of the Milky Way — where the violent deaths of stars usually leave chaos and crumpled ...

ASKAP detects a perfectly spherical supernova remnant called ‘Telios’ Telios’ true distance and size remain unclear due to ...

More information: Miroslav D. Filipovic et al, Teleios (G305.4-2.2)—the mystery of a perfectly shaped new Galactic supernova remnant, arXiv (2025). DOI: 10.48550/arxiv.2505.04041 ...

Teleios, a supernova remnant with perfect symmetry, was discovered using ASKAP. Its properties suggest a Type Ia origin and call for further high-resolution observation.

Near the center of our galaxy ... That means it originated from a star and is the remnant of a supernova. However, supernova remnants generate X-rays as well, and no X-rays have been detected ...
