Astronomers have found possible proofs of stellar vampirism in the globular cluster 47 Tucanae. Using ESO’s Very Large Telescope (VLT), they found that some hot, bright, and apparently young stars in the cluster present less carbon and oxygen than the majority of their sisters. This indicates that these few stars likely formed by taking their material from another star.

A new map developed by an international team of astronomers should help you find your way around the Universe – at least to a distance of 600 million light years. This new 3-dimensional map plots out the locations of all the major superclusters of galaxies and the voids that surround them. It includes “The Great Attractor” and a supercluster called “Shapley” that lies about 400 million light years away and spans 20 million light years. The map was developed using data from the 2MASS Redshift Survey, which calculated the redshifts (and therefore the distances) of 25.000 galaxies across the entire sky, and the Two Micron All Sky Survey, which provided the colours and two-dimensional positions of the galaxies.
