Description

This photograph from the NASA/ESA Hubble Space Telescope presents the first clear view of one of the hottest known stars, the central star of nebula NGC 2440 in our Milky Way galaxy. The superhot star, called the NGC 2440 nucleus is the bright white dot in the center of this photograph.

In previous photographs made with telescopes on the ground, blurring due to the Earth's atmosphere acted to smear together the light from the star with the glow of the surrounding nebula. By clearly separating the starlight from the nebular glow, astronomers have been able to make the most accurate estimate yet for the star temperature: a torrid 200000 degrees Celsius (or 360000 degree Fahrenheit) or more.
