Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA’s Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.

This work is based on Chandra observations of the remains of a supernova called Cassiopeia A, located in our galaxy about 11,000 light-years from Earth. This is one of the youngest known supernova remnants, with an age of about 350 years.

科学家们发现了一颗著名的超新星喷发出的钛碎片。这一发现是由美国宇航局的钱德拉X射线天文完成的,可能是准确指出一些巨型恒星如何爆炸的重要一步。

这项工作是基于钱德拉对仙后座A超新星残骸观测仙后座A位于距离地球约11000光年的银河系中。这是已知的最年轻的超新星遗迹之一,约有350年的历史
