Great Jupiter's Ghost
Above is a composite image of NGC 3242, sometimes called the "Ghost of Jupiter Nebula". The "Ghost of Jupiter" is a planetary nebula which is the death shroud of an old sun-like star. This phantasmagorical picture combines an optical image from the Hubble Space Telescope with an X-ray image from the XMM-Newton X-ray Observatory. The Hubble image shows the outer, ionized shell of gas, while the X-ray image highlights the extremely hot gas (in blue) which fills the interior of the shell. This hot gas is produced as a fast wind from the dead stellar core plows into the expelled former atmosphere of the star in a final death scream. This Halloween, we'll learn of the fate of the Hubble Space Telescope, as NASA decides if it's worth it to the risk a space shuttle mission to service Hubble. Trick or treat?
