Totality occurs along a narrow path on Earth where it intersects with the umbra (darkest part) of the Moon’s shadow. Image: Mechanism of a total solar eclipse. Most people miss out on being along the path of totality or annularity. Some solar eclipses are central, which means that the Moon and Sun are seen in exactly the same direction, with the Sun being completely hidden (a total solar eclipse) or the Moon’s silhouette appearing completely within the Sun’s disc (an annular solar eclipse).Ĭentral solar eclipses take place on average every 7.8 months, but are seen from along a relatively narrow path across Earth’s surface.Īn observer in the penumbra (the lighter part) of the shadow witnesses only a partial eclipse this region covers a far larger area. This means that under ideal circumstances, the Moon can completely cover the Sun, but only briefly. Remarkably, the Sun and the Moon appear almost exactly the same size to us this is because although the Moon is about 400 times smaller than the Sun, it is also about 400 times closer. Solar eclipseĪ solar eclipse occurs when the Moon passes in front of the Sun as seen from Earth, blocking part or all of its light. The QVMAG Library and Archives Sub-menuĪn eclipse happens when one celestial body enters the shadow cast by another - cutting off its source of light - or is obscured from view by a body passing in front of it (although certain of these events, such as the Moon obscuring distant stars, are more correctly called occultations).įrom Earth, we see two types of eclipses related to the Sun and the Moon: solar eclipses and lunar eclipses.From the Vault: stories from the collection.Women's Art Prize Tasmania 2022 Finalists Exhibition.The 3 M's: miniatures, models and memories.2023 Tasmanian Art Teachers Association, Members Exhibition.Southern Sky Astrophotography: 2022 David Malin Awards.PHD Student Examination Exhibition: Suzanne Crowley.Precious: excellence in contemporary jewellery.I Shed My Skin, A Furneaux Islands Story.Face Time: The stories and faces from St Giles 85 years.The Great War 1914-18: sacrifice and shadows.Dinosaur rEvolution: secrets of survival.Centenary of the Royal Society: a right royal effort.Archie 100: A Century of the Archibald Prize.Transforming the Island: railways in Tasmania.Tasmanian Tiger: precious little remains.
