Fodor's Expert Review Armagh Observatory and Planetarium

Displayed here in all its nickel-iron glory is Ireland's largest meteorite, an astonishing 4.5 billion years old and weighing 336 pounds. Elsewhere, find a spaceship, satellite models, a moon map on which you can walk, and the Digital Theater with Digistar 5—sit back and navigate the night sky in the company of experts. Weekend children's activities include building and launching rockets. Outside, stroll through the solar system and the Milky Way at the huge scale model of the universe.
