How to view Thursday's solar eclipse with a shoebox
A potentially amazing partial solar eclipse is due to darken skies above North America Thursday (Oct. 23), and you can build and easy tool to help you view it safely.
It isn't safe to look directly at the sun during any eclipse of the sun, and the听听听is no exception. Even though the moon is passing in front of the start from Earth's perspective, the sun is still incredibly bright and looking directly at it can damage any skywatcher's eyesight. Instead of looking straight at Earth's closest star, observers still interested in seeing the partial eclipse can use a听鈥� an easy tool made with household items.
A pinhole camera projects sunlight through a small hole in a box onto the other side of the box, allowing you to see a view of the sun safely without risking your eyesight. To create a pinhole camera, all you need is a shoebox, some white paper and foil. Once your creation is ready, you can see the progression of the partial eclipse with ease. []
You can also use some crafty skills and a pair of binoculars to create a solar eclipse projector for Thursday's event. To do that you'll need: a air of binoculars; a tripod or stack of books, duct tape; scissors; and two pieces of cardboard. You can use our听.
Thursday's partial solar eclipse should be visible, weather permitting, to people across a wide swath of North America, and even if you can't catch the eclipse from your part of the world, you can see it live online. The online Slooh Community Observatory will host a live webcast听with expert commentary听on its website听starting at 5 p.m. EDT (2100 GMT) on Thursday. Another webcast will be hosted by the Griffith Observatory in Los Angeles, California.听

Thursday's solar eclipse could act as a preview for another eclipse that should be visible to people around the United States in 2017, according to one eclipse expert.
"This partial eclipse visible to people looking through sun-safe filters on Thursday is a coming attraction for the August 21, 2017, eclipse that will have the moon entirely covering the sun in a 60-mile-wide band across the U.S. from Oregon to South Carolina, with 80 percent or more of the sun covered from most of the continental U.S.," Jay Pasachoff听.
奥础搁狈滨狈骋:听Never stare directly at the sun through binoculars, an unprotected telescope or your unaided eye. Serious eye damage can result. Astronomers use protective filters or solar eclipse glasses to safely observe the sun.听
"The sun is so bright that even through ordinary sunglasses you can damage your eyes if you stare at it," Pasachoff added. "The special solar filters that are available, which are made of a black polymer, block out all but about a thousandth of a percent of the sun's brightness, while ordinary sunglasses would dim the Sun by only a relatively small bit even in the visible while allowing almost all the hazardous infrared to come through."
