Cats across the galaxy are in mourning after famous feline fanatic Sir Patrick Moore passed away at his home in West Sussex, with his black cat Ptolemy at his bedside.
Throughout his life the celebrated astronomer was a key supporter of local charity Cats Protection, and donated many of the proceeds from his twelve books to the organisation.
The charity has released a statement on its website expressing its sadness at the loss of Sir Patrick, who is described as a "lifelong cat lover".
Ptolemy is the latest in a long line of feline companions owned by Sir Patrick, and is the second to be given that name after his first ever cat, who he says "followed me everywhere I went" as a small boy.
The name Ptolemy is taken from a Greek geographer, mathematician, astronomer and astrologer.
Above the front door of Sir Patrick's home is a sign saying "this house is run entirely for the benefit of our cats".
