NGC 2440
This nebula is powered by an incredibly hot central star (not shown in this image). The central star, a white dwarf, is enshrouded by the cocoon of gas that it shed a few tens of thousands of years ago. It is estimated that the temperature of this star may hold the current record (in our galaxy) at over 300,000 degrees Fahrenheit. Hubble Space Telescope images have captured both the central star and the complex gas cloud that surrounds it.
This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.
