Ignite from your dust and shadow,
the fire of your shine.

I want to see you in the night sky,
so I can find the way to my own light.

This team of Uruguayan and Mexican researchers found strong evidence of the existence of a middle age (2-5 Gyr) RR Lyrae star in Trumpler 5 star cluster. This challenges the existing evolutionary models and points out the role of binary associations as early producers of this type of stars.
