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.
