This mosaic shows the Carina Nebula (left part of the image), home of the Eta Carinae stellar system. This part was observed with the MPG/ESO 2.2-m telescope at ESO’s La Silla Observatory. The middle part shows the direct surrounding of the star system: the Homunculus Nebula, created by the ejected material from the Eta Carinae system. This image was taken with ESO’s Very Large Telescope. The right image shows the innermost part of the system as seen with ESO’s Very Large Telescope Interferometer/ It is the highest resolution image of Eta Carinae ever.
