A new exhibition - 'Planet Earth: Our Place In Space' - was recently opened at the National Museum of Ireland in Co. Mayo. This temporary exhibition will feature a sample of moon rock, complete with an Irish tricolour flag that was brought to the moon. Other exhibits will include meteorites тАУ rocks from space that are debris from the early solar system. A highlight is the Limerick meteorite that fell near Adare, County Limerick in 1813, IrelandтАЩs largest ever meteorite weighing in at 27 kilos. These specimens will be used to explain what meteorites tell us about the early solar system and also what we know about the earth as a planet. Minerals and rocks will further illustrate what the earth is made of and its nature as a planet.
