IMAGES The Centre of the Milky Way Galaxy as Seen by Chandra

This 400 by 900 light-year mosaic of several Chandra images of the central region of our Milky Way galaxy reveals hundreds of white dwarf stars, neutron stars and black holes bathed in an incandescent fog of multi-milliondegree gas. The supermassive black hole at the centre of the galaxy is located inside the bright white patch in the centre of the image. The colours indicate X-ray energy bands: red (low), green (medium) and blue (high). The mosaic gives a new perspective as to how the turbulent galactic centre region affects the evolution of the galaxy as a whole. (See also $3). [Courtesy: NASA]

This morphology may have resulted from the presence of a topographic obstruction to the south-east of the vent. The Jet Propulsion Laboratory, Pasadena, CA manages the mission for NASA’s Office of Space Science, Washington, DC.

Four views of Euboea Fluctus on Jupiter’s moon lo showing changes seen on 27 June 1996 by the Galileo spacecraft as compared to views seen by the Voyager spacecraft during the 1979 flybys. Clockwise from upper left is a Voyager 1 high resolution image, a Galileo enhanced colour image, a Galileo image with simulated Voyager colours, and a Voyager 2 colour image. North is to the top of the picture. The Galileo images show new diffuse deposits which have an unusual morphology for plume deposits. A diffuse yellowish deposit with a radius of 285 km extends to the north-west, whereas an intense reddish deposit marks a curving fallout margin to the south-east.
