A new image of the center of the Milky Way combines data from NASA's three Great Observatories. In this image, X-rays from Chandra are blue and violet, near-infrared emission from Hubble is yellow, and Spitzer's infrared data are red. Large prints of this image were distributed to some 150 U.S. planetariums, science centers and others as part of the International Year of Astronomy 2009 activities.

In this holiday season of home cooking and carefully-honed recipes, some astronomers are asking: what is the best mix of ingredients for stars to make the largest number of plump black holes? They are tackling this problem by studying the number of black holes in galaxies with different compositions. One of these galaxies, the ring galaxy NGC 922, is seen in this composite image containing X-rays from NASA's Chandra X-ray Observatory and optical data from the Hubble Space Telescope.

"No star is ever lost we once have seen, We always may be what we might have been." - Adelaide Anne Procter. NGC 6543: Also known as the Cat's Eye, this planetary nebula is located about 3,000 light years from Earth. (Credits: X-ray: NASA/CXC/RIT/J.Kastner et al.; Optical: NASA/STScI)

We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light. - Plato

A mysterious X-ray signal has been found in a detailed study of galaxy clusters using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. One intriguing possibility is that the X-rays are produced by the decay of sterile neutrinos, a type of particle that has been proposed as a candidate for dark matter. chandra.harvard.e...
