“During each outburst, the star expelled material in a different direction. This can be seen in the two bow tie-shaped lobes.

“The nebula also is rich in clouds of dust, some of which form long, dark streaks pointing away from the star.

“NGC 2440 lies about 4,000 light-years from Earth in the direction of the constellation Puppis.”
