* Astronomy

An 1822 celestial atlas by Scottish amateur astronomer Alexander Jamieson is a star item at this year's Christian Aid charity book sale in Edinburgh, one of the largest sales of its kind in the world.
The second-hand book bonanza, held annually for the last 35 years at the Church of St Andrew's and St George's in the city centre, opens on Saturday and then runs through from May 11 to 15. It has raised some 1.7 million pounds ($2.58 million) for the charity over the years.
