Astronomers have used the ESO's Very Large Telescope (VLT) to observe the Sun-like star HIP 102152. The object, which resides 250 light-years away, is a solar twin exhibiting very similar attributes to our own Sun. HIP 102152 is nearly four billion years older than the Sun, a characteristic that has provided a valuable insight into the link between the age of a star and the amount of lithium it carries.
