Popis:
An X-Ray image of NGC 6543 has revealed a bright central star surrounded by a cloud of multimillion-degree gas in the planetary nebula known as the Cat's Eye Nebula. This image of the Chandra X-Ray Observatory, where the intensity of the X-ray emission is correlated to the brightness of the orange coloring, captures the expulsion of material from a star that is expected to collapse into a white dwarf in a few million years. The intensity of X rays from the central star was unexpected, and it is the first time astronomers have seen such X-ray emission from the central star of a planetary nebula. The ACIS X-ray camera aboard Chandra observed NGC 6543 from May 10-11, 1999 for a total exposure time of 46,000 seconds.

Kočičí oko (mlhovina)Mlhovina Kočičí oko je planetární mlhovina v souhvězdí Draka. Z hlediska struktury je to jedna z nejsložitějších známých mlhovin. Ve vysokém rozlišení Hubbleova vesmírného dalekohledu v ní lze pozorovat nevšední struktury – chomáče, výtrysky, vlákna a „obloukové rysy“. .. pokračovat ve čtení
