The Milky Way seems to be missing nearly half of its regular matter

Measurements of a blast of radio waves passing through our galaxy have shown that the Milky Way's proportion of visible matter is 40 per cent lower than the rest of the universe

Illustration of the Milky Way galaxy as it might appear edge on. The Milky Way is a barred spiral galaxy roughly 100000 light-years in diameter. It is flat, shaped like two fried eggs back-to-back. At the centre is the nucleus, a vast flattened ball of old, red stars orbiting a supermassive black hole. This view imagines our galaxy seen from far from its nucleus, within the galactic plane. A lane of dust bisects the galaxy. Globular clusters (spherical clusters of stars) orbit here. One is seen in close up on the lower right.

New Chandra observations have been used to make the first detection of X-ray emission from young stars with masses similar to our Sun outside our Milky Way galaxy. The Chandra observations of these low-mass stars were made of the region known as the "Wing" of the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors. In this composite image of the Wing the Chandra data is shown in purple, optical data from the Hubble Space Telescope is shown in red, green and blue and infrared data from the Spitzer Space Telescope is shown in red. Astronomers call all elements heavier than hydrogen and helium - that is, with more than two protons in the atom's nucleus - "metals". The Wing is a region known to have fewer metals compared to most areas within the Milky Way. The Chandra results imply that the young, metal-poor stars in NGC 602a produce X-rays in a manner similar to stars with much higher metal content found in the Orion cluster in our galaxy.

The very centre of the Milky Way has an unexpectedly low density of cosmic rays compared with the rest of the galaxy, which means that they are somehow being kept out
