NGC 2014 and NGC 2020
(Preview)
Two very different gas clouds in the galaxy next door ESO's Very Large Telescope has captured an intriguing star-forming region in the Large Magellanic Cloud - one of the Milky Way's satellite galaxies. This sharp image reveals two distinctive glowing clouds of gas: red-hued NGC 2014, and its blue...

ESO's Telescopes Uncover Super Star Cluster in the Milky Way.
Until now, super star clusters were only known to exist very far away, mostly in groups of interacting galaxies. Now, however, a team of European astronomers have uncover one within our own Galaxy.
The newly found massive structure...

PN G75.5+1.7
(Preview)
It looks like a soap bubble or perhaps even a camera fault, but the image at right is a newly discovered planetary nebula. Planetary nebulae, which got their name after being misidentified by early astronomers, are formed when an ageing star weighing up to eight times the mass of the sun ejects its out...
