Stunning Hubble image of the planetary nebula NGC 2440, a bow-tie shaped cloud of gas and dust expelled by a dying star. The nebula's intricate structure and the incredibly hot central star (200,000 Kelvin!) are clearly visible in this false-color image. Located 4,000 light-years away in the constellation Puppis, it spans over a light-year. This image showcases the continued impressive imaging capabilities of Hubble's Wide Field Planetary Camera 2.
