Chaos reigns in the center of this butterfly-shaped nebula in the constellation Puppis. NGC 2440 is a planÂeÂtary nebÂula and is the remains of a star like our Sun. The complex structure within the center of this nebula suggest to astronomers that the star has ejected material periodically in various directions.

In the starry gardens of the constellation of Puppis, you’ll find this butterfly or spider-looking nebula. NGC 2440 is a planetary nebula and is the remains of a star like our Sun. The central star cast off its outer layers as it came to the point where it could no longer keep up nuclear fusion in its core.

Find the white dot in the center of the nebula.
