Astronomers Find a Nearby Star That a Spitting Image of a Young Sun

If we had a time machine, we could travel to the distant past and observe the Sun’s youth directly. But since that’s not possible, we can do the next best thing. Look for young stars that are very similar in size and composition to our Sun. The spitting image of the Sun, if you will. This has been done before with older stars. HIP 102152, for example, is a solar doppelganger that’s about 4 billion years older than our Sun. Now a team has studied a young solar doppelganger known as kappa-1 Ceti.

This is an initial study, so the connection to life is tenuous. But the team hopes to gather data from other Sun-like stars at various ages. With more observations, they will be able to fine-tune their model and create a more accurate history of the Sun.
