clumpy and lumpy

Read NASA's article on the clumpy and lumpy death of a star. Poor star.

Scientists have been studying the latest images of the Tycho supernova remnant in Cassiopeia with the Chandra X-ray telescope. They emphasised the clumpy regions of the type 1A object with different colours. In particular the red parts are moving away from us.

The researchers are not sure why the SN 1572 remnant is so clumpy but one proposal is that there were multiple ignition events.
