The dark side of globular star clusters
Observations with ESO's Very Large Telescope in Chile have discovered a new class of "dark" globular star clusters around the giant galaxy Centaurus A. These mysterious objects look similar to normal clusters, but contain much more mass and may either harbour unexpected amounts of dark matter, or contain massive black holes — neither of which was expected nor is understood.
The Night Sky
Even casual observers cannot fail to notice dazzling Venus currently gracing the western horizon at dusk. Owing to a favourable set of circumstances, the brightest planet is visible long after sunset. How late can you see it set in the British Isles? For those north of the Arctic Circle, Venus is presently circumpolar and doesn't set at all!
Picture This
The enigmatic white features on the dwarf planet Ceres are better resolved in a new sequence of images taken by NASA's Dawn spacecraft on May 3rd and 4th. In this closest-yet view, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. However, their exact nature remains unknown.
