Today, tens of thousands of people are gathering in northeastern Australia to witness one of the most amazing and dramatic astronomical events known: a total solar eclipse. At 2:39 p.m. EDT (19:39 UT) the Moon will begin to pass in front of the Sun for viewers around Cairns, Australia, leading up to a brief period of totality at 5:12 p.m. EDT (22:12 UT). At this time, the Sun will be completely blocked by the disk of the Moon, revealing the wispy strands of the Sun’s outer corona. It will be a spectacular view that’s possible at no other time, and will give scientists a chance to study some curious aspectsof the Sun’s atmosphere.
“On a scale of one to ten, a total solar eclipse is a MILLION.” – Fred Espenak, aka “Mr. Eclipse“
