... Deep optical CCD image of the LMC. Diffuse Galactic Light is plainly visible in this optical image of the Large Magellanic Cloud as a haze over the entire galaxy. The phenomenon arises from starlight scattering off numerous dust clouds in and above the plane of the LMC's disk to form a faint, galaxy-wide reflection nebula. ... The CCD image above was presumably taken with a special wide-field camera at optical wavelengths. ...

. ATLAS is a project to image seven square degrees of sky, in two fields (CDF-S and ELAIS-S1), at radio wavelengths, to an rms of about 15 Jy, making it the widest deep radio survey aver attempted. The fields are chosen to cover the Spitzer Wide-Area IR Extragalactic Survey (SWIRE), and the radio images cut through the dust, to trace the cosmic history of AGN and star-forming galaxies.

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
