| Description | Planetary nebulae (PNe) consist of stellar material ejected by stars with masses less than 8-10 solar masses. The current fast stellar wind sweeps up the previous slow wind to form the observed nebular shells, but jets and fast collimated outflows may also be responsible for shaping PNe at early evolutionary stages. These dynamic interactions produce hot, shocked gas that emits X-rays. We have selected a sample of 10 PNe evenly divided between the two main morphological classes, elliptical and bipolar, and spanning a wide range of evolutionary stages. We request XMM-Newton observations of these PNe in order to determine their physical structures and to study the formation, shaping, and evolution of elliptical and bipolar PNe. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
