NGC 2440: Cocoon of a New White Dwarf!

What's that in the center? Like a butterfly, a white dwarf star begins its life by casting off a cocoon of gas that enclosed its former self.

In this analogy, however, the Sun would be a caterpillar and the ejected shell of gas would become the prettiest cocoon of all. In the featured cocoon, the planetary nebula designated NGC 2440 contains one of the hottest white dwarf stars known.

The white dwarf can be seen as the bright orange dot near the image center.

Our Sun will eventually become a white dwarf butterfly, but not for another 5 billion years

NGC 2440 Nucleus: The Hottest Star? - November 30th, 1995.

"In the center of the above photograph lies a star with one of the hottest surface temperatures confirmed. This bright white dwarf star's surface has been measured at greater than 200,000 degrees Celsius - more than 30 times hotter than that of our own Sun. The white dwarf's extreme heat makes it glow extraordinarily bright: intrinsically more than 250 times brighter than the Sun. The star is at the center of the planetary nebula titled NGC 2440, which lies inside our Milky Way galaxy. The above computer sharpened image was taken by the Hubble Space Telescope."

Planetary nebula NGC 2440 is a relic of a star once like our Sun that has cast off its outer layers of gas, forming a colorful cocoon around the star's remaining core.

.Esto ocurría muy, muy lejos de casa cuando nos conocimos.

Hubble examined this part of the sky, located near the Big Dipper and called the GOODS-North field, as part of the Great Observatories Origins Deep Survey (GOODS).

.Así de hermoso se veía el universo la noche que empezó todo.
