How can I watch the solar eclipse?
If you’re not in an area in which the total eclipse is viewable, you’ll be able to follow the live stream that takes place between 12 noon and 4pm EDT (in the UK that's 5pm and 9pm BST). The stream is embedded at the top of this page.
NASA's Facebook page will also offer a 4K, 360 live stream of the solar eclipse from Charleston, South Carolina. This stream will be live between 1.15pm and 4.15pm with totality occurring at 2.45pm ET.
Areas within the path of totality - a circa-70 mile-wide stretch between Salem, Oregon and Charleston, South Carolina, which includes Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee and Georgia - will be able to view a total solar eclipse.
The path of totality is illustrated below.
What do I need to watch the solar eclipse?
NASA recommends that you will need a pair of Eclipse glasses (not sunglasses) - a selection is available via Amazon (and Amazon UK) - or a pinhole projector. You can make your own using the templates provided at NASA’s site.
The glasses or projector should be used at all times except totality.
What is a total solar eclipse?
A total solar eclipse occurs when the moon passes in front of the sun, completely blocking our view of it.
In the last few seconds before it reaches totality you can see a Diamond Ring, which is just the sun’s outer edge shining through. Following this is Baily’s Beads, whereby only valleys on the moon’s surface allow sunlight to escape.
When totality occurs darkness falls on earth. This may last under a minute - the longest total eclipse will occur is near Carbonade, Illinois, where it will last 2 minutes 40 seconds.
When the moon begins to pass by the sun you will see a crescent shape.
