Using NASA’s Chandra X-ray Observatory, astronomers have discovered new evidence on what triggered an historic supernova explosion.
The discovery also provides strong evidence that a star can survive the explosive impact generated when a companion star goes supernova.
The new study examined the remnant of a supernova observed by the Danish astronomer Tycho Brahe in 1572.
The object, dubbed Tycho for short, was formed by a Type Ia supernova, a category of stellar explosion useful in measuring astronomical distances because of their reliable brightness.
The researchers analysed a deep Chandra observation of Tycho and found an arc of X-ray emission in the supernova remnant.
