A density map of part of the Milky Way disk; the axes show galactic latitude and longitude, coordinates that relate to the position of the centre of the Galaxy; the mapped data are the counts of stars detected in i, the longer wavelength broad band of the survey, down to a faint limit of 19th magnitude; although this is just a small section of the full map, it portrays in exquisite detail the complex patterns of obscuration due to interstellar dust.

An artist's conception of the young massive star HD100546 and its surrounding disk. A planet forming in the disk has cleared the disk within 13 astronomical units of the star, a distance comparable to that of Saturn from our Sun. As gas and dust flows from the circumstellar disk to the planet, this material surrounds the planet as a circumplanetary disk (inset). These rotating disks are believed to be the birthplaces of planetary moons, such as the Galilean moons that orbit Jupiter. Image credit: P. Marenfeld / NOAO / AURA / NSF.

A slice of the Laniakea Supercluster in the supergalactic equatorial plane. Our Milky Way Galaxy is located at the black dot at the origin of the supergalactic coordinates system. The colors represent density within this slice, with red for high densities and blue for voids - areas with relatively little matter; individual galaxies are shown as white dots; velocity flow streams within the region gravitationally dominated by Laniakea are shown in white, while dark blue flow lines are away from the Laniakea local basin of attraction; the orange contour encloses the outer limits of these streams, a diameter of about 522 million light-years.

H-ATLAS J142935.3-002836, an object seen by the Hubble Space Telescope and the Keck-II telescope on Hawaii with the help of a gravitational lens. In this image one can see the foreground galaxy that is doing the lensing, which resembles how our Milky Way Galaxy would appear if seen edge-on; but around this galaxy there is an almost complete ring - the smeared out image of a star-forming galaxy merger far beyond.
