Supernova explosions are truly amazing!
The rich detail has already paid off. Astronomers spotted previously unseen jets of material shooting in opposite directions ahead of the main, expanding cloud of material. The jets reach about 10 light-years from the neutron star.
"The presence of the bipolar jets suggests that jets could be more common in relatively normal supernova explosions than supposed by astronomers," said Una Hwang of NASA's Goddard Space Flight Center.
May be detailed observations such as these will help scientists to find out the real process causing these fast-moving jets. The neutron star/black hole must be moving so fast that it can throw the gas around at almost the speed of light.
The jets/rings of SN1987A were also interesting.
Chandra first imaged the exploded remains five years ago as its initial target after being launched into orbit. That exposure lasted about 90 minutes.
Here is the old picture (August 1999). Not many details here:
