|Description||Core-collapse supernova remnants (CC-SNRs) show strong anisotropies in the ejecta that can trace pristine structures in the explosion.Vela SNR shows ejecta shrapnel beyond the main shock shell. We have shown that two of them (A,G), located in opposite directions of the SNR center,are Si-rich,while all the other shrapnel show no Si.Our result suggests that a jet-counter-jet Si-rich structure could have been formed in the SN explosion,though the detection of only two knots does not provide a conclusive evidence. We propose to observe a bright region behind shrapnel G. The detection of overabundant Si in this region will prove the presence of an extended,collimated feature,allowing us to obtain estimates on its mass and kinetic energy, which are crucial for our understanding of CC-SNe|

|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.
