... 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. ...

M31, also known as the Andromeda Galaxy, is the nearest large galaxy to our own. ... M31 is about 4 times as massive as the Milky Way. It has a substantially large population of globular clusters (about 600) than does the Milky Way. The overall star formation rate in M31 is remarkablely low compared to other spiral galaxies. M31 and the Milky Way are bound together (maybe?) in a configuration known as the Local Group of Galaxies. ... This image is another unique image. ...

One of Planck's first images is shown as a strip superimposed over a two-dimensional projection of the whole sky as seen in visible light. ... The prominent horizontal band is light from our Milky Way galaxy. The Planck image shows how the sky looks at millimeter-long wavelengths. Red areas are brighter, blue areas are darker. The large red strips show the Milky Way. ... Planck is measuring the sky at nine wavelengths of light, one of which is shown here. ...
