Over the years NASA have launched plenty of probes and spacecraft in to the far reaches of the solar system, yet there is still no evidence of any other life.
However, the spacecraft Dawn has been taking a close look at the asteroid belt between Mars and Jupiter, where there are two dwarf planets called Vesta and Ceres. As Dawn gets closer to Ceres, a strange sight has appeared and it looks like lights! Surely, these small planets cannot support life, but there is something strange going on. According to Andreas Nathues, from the Max Planck Institute for Solar System Research, Gottingen, Germany, this seems to be a complete mystery that is yet to be solved;
The brightest spot continues to be too small to resolve with our camera, but despite its size it is brighter than anything else on Ceres. This is truly unexpected and still a mystery to us
