From its highly elliptical orbit around Earth (the observatory makes it one-third of the way to the moon), Chandra has spotted some of the strangest, most charismatic and curious objects in the solar system ... and beyond.
} "Attaques au mortier" ou feux d'artifice ? At the time of this image, the supernova was visible with the unaided eye. If enough of the dust created by 1987A and other supernovas like it transitions into interstellar space, it could explain part of why many galaxies in the early universe got their copious amounts of dust, Indebetouw said. From theoretical and spectroscopic evidence, SN 1987A is known to be expanding rapidly with the outer regions of the exploding star being ejected at speeds between 2,000 and 30,000 kilometers (1,245 to 18,640 miles) per second.

En se servant des clichés de Chandra et d’autres observatoires, la Nasa a produit des images composites qui démontre les capacités de l’astronomie ”multi-longueur d’onde” qui donne accès à l’observation d’un objet à différentes longueurs d’ondes et permet de rendre compte de sa réelle complexité. Il a observé une grande variété de structures astronomiques comme les amas de galaxies, les trous noirs actifs ou les supernovas. HST (green) and Chandra (blue) show the expanding shockwave. In this image, taken with the European Space Agency's Faint Object Camera (FOC), HST's 0.07 are second resolution reveals clumpy structure in the ring which indicates that the material is not uniformly distributed.
