First impressions can be deceptive – astronomers have used ESA's X-ray satellite XMM-Newton to find a massive black hole hungrily feeding within a tiny dwarf galaxy, despite there being no hint of this black hole from optical observations.(learn more)

The face-on Pinwheel spiral galaxy is seen at ultraviolet wavelengths in this image taken by ESA’s XMM-Newton space telescope.

Also known as M101, the galaxy lies 21 million light-years away in the constellation Ursa Major. It measures 170 000 light-years across – nearly twice the diameter of our own Milky Way Galaxy – and contains at least a trillion stars. About a billion of these stars could be similar to our own Sun.(read more)

Neutron star bites off more than it can chew

Source: ESA News

ESA’s XMM-Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10 000 times its normal brightness. Astronomers believe the outburst was caused by the star trying to eat a giant clump of matter.

The flare took place on a neutron star, the collapsed heart of a once much larger star. Now about 10 km in diameter, the neutron star is so dense that it generates a strong gravitational field.

The clump of matter was much larger than the neutron star and came from its enormous blue supergiant companion star.(read more)
