    A new star has been gifted to the "dark sky island" of Sark.

    Sark Observatory Society spent Saturday evening looking up for the "1565" star which belongs to the corona borealis constellation.

    Its number reflects the year the island was given its royal charter by Queen Elizabeth I on 6 August 1565.

    The galactic gift was presented to one of the island's observatory guides for his birthday last year.

    Annie Dachinger, of the Society, described it as an "honour" for the island.

    She said it was an "exciting" opportunity to catch a closer glimpse of the star on Saturday.

    "The skies are very clear here, and there's no pollution, either day or night, so you get to see a lot of stars", she said.

    "It's quite colossal".
