Cartão Postal Space Cat Galaxy

Foreground: Space Cat, Background: A composite image of the Antennae galaxies contains X-rays from the Chandra Telescope (blue), visible light data from Hubble Telescope (gold and brown), and infrared data from the Spitzer Telescope (red). The X-ray image shows huge clouds of hot, interstellar gas that have been injected with rich deposits of elements from supernova explosions. This enriched gas, which includes elements such as oxygen, iron, magnesium and silicon, will be incorporated into new generations of stars and planets. The bright, point-like sources in the image are produced by material falling onto black holes and neutron stars that are remnants of the massive stars.
