About The Event
Entry to tonight's event is free for members. We ask non-members to make a donation of £2 (on the door) to help us keep the cake and biscuit supplies going.
Tonight we'll be exploring one of our nearest neighbours - Barnard's Star. It is a red dwarf of the dim spectral type M4 and is too faint to see without a telescope; its apparent magnitude is 9.5, but is fascinating in many ways
At 7–12 billion years of age, Barnard's Star is considerably older than the Sun, which is 4.5 billion years old, and it might be among the oldest stars in the Milky Way galaxy.
