Decades of searching in the Milky Way’s nearby ‘twin’ galaxy Andromeda have finally paid off, with the discovery of an elusive breed of stellar corpse, a neutron star, by ESA’s XMM-Newton space telescope. Andromeda, or…


An Andromeda X-Ray

NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has captured the best high-energy X-ray view yet of a portion of our nearest large, neighboring galaxy, Andromeda. The space mission has observed 40 “X-ray binaries” — intense…


Small Shooting Stars

By chance, two meteoroids flew across the foreground of this image of the Andromeda Galaxy. They are out of focus because they are too close. The brighter meteoroid changes intensity partway across. The arc shaped…


A very, very glorious halo

Scientists using NASA’s Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and 1,000 times more massive than previously…



A 1.5 billion pixel picture

This sweeping view shows one third of our galactic neighbour, the Andromeda Galaxy, with stunning clarity. The panoramic image has a staggering 1.5 billion pixels – meaning you would need more than 600 HD television…


Is it too late already for our Milky Way?

All galaxies grow by pulling in cosmic debris, gas and dust, and are rather efficient at converting it into new stars. But as galaxies age and grow more massive over time, their ability to create…
