How to Safely Watch the Aug. 21 Solar Eclipse
On Aug. 21, 2017, a solar eclipse will be visible in North America. Throughout the continent, the Moon will cover part – or all – of the Sun’s super-bright face for part of the day.
Since it’s never safe to look at the partially eclipsed or uneclipsed Sun, everyone who plans to watch the eclipse needs a plan to watch it safely. One of the easiest ways to watch an eclipse is solar viewing glasses – but there are a few things to check to make sure your glasses are safe:
Glasses should have an ISO 12312-2 certification
They should also have the manufacturer’s name and address, and you can check if the manufacturer has been verified by the American Astronomical Society
Make sure they have no scratches or damage
To use solar viewing glasses, make sure you put them on before looking up at the Sun, and look away before you remove them. Proper solar viewing glasses are extremely dark, and the landscape around you will be totally black when you put them on – all you should see is the Sun (and maybe some types of extremely bright lights if you have them nearby).
Never use solar viewing glasses while looking through a telescope, binoculars, camera viewfinder, or any other optical device. The concentrated solar rays will damage the filter and enter your eyes, causing serious injury. But you can use solar viewing glasses on top of your regular eyeglasses, if you use them!
If you don’t have solar viewing glasses, there are still ways to watch, like making your own pinhole projector. You can make a handheld box projector with just a few simple supplies – or simply hold any object with a small hole (like a piece of cardstock with a pinhole, or even a colander) above a piece of paper on the ground to project tiny images of the Sun.
Of course, you can also watch the entire eclipse online with us. Tune into nasa.gov/eclipselive starting at noon ET on Aug. 21!
For people in the path of totality, there will be a few brief moments when it is safe to look directly at the eclipse. Only once the Moon has completely covered the Sun and there is no light shining through is it safe to look at the eclipse. Make sure you put your eclipse glasses back on or return to indirect viewing before the first flash of sunlight appears around the Moon’s edge.
You can look up the length of the total eclipse in your area to help you set a time for the appropriate length of time. Remember – this only applies to people within the path of totality.
Everyone else will need to use eclipse glasses or indirect viewing throughout the entire eclipse!
Photographing the Eclipse
Whether you’re an amateur photographer or a selfie master, try out these tips for photographing the eclipse.
#1 — Safety first: Make sure you have the required solar filter to protect your camera.
#2 — Any camera is a good camera, whether it’s a high-end DSLR or a camera phone – a good eye and vision for the image you want to create is most important.
#3 — Look up, down, and all around. As the Moon slips in front of the Sun, the landscape will be bathed in long shadows, creating eerie lighting across the landscape. Light filtering through the overlapping leaves of trees, which creates natural pinholes, will also project mini eclipse replicas on the ground. Everywhere you can point your camera can yield exceptional imagery, so be sure to compose some wide-angle photos that can capture your eclipse experience.
#4 — Practice: Be sure you know the capabilities of your camera before Eclipse Day. Most cameras, and even many camera phones, have adjustable exposures, which can help you darken or lighten your image during the tricky eclipse lighting. Make sure you know how to manually focus the camera for crisp shots.
#5 —Upload your eclipse images to NASA’s Eclipse Flickr Gallery and relive the eclipse through other peoples’ images.

It’s time for a musical World Record Wednesday! The “Golden Record,” created by NASA and placed on both Voyager spacecraft in 1977, is the phonographic recording to travel farthest. Currently hurtling through space at a distance of over 12 billion miles from Earth on Voyager I, the album is literally a “world record"—a collection of sounds, songs, and short speeches intended to represent the best of planet Earth and humanity. The tracks were carefully curated by NASA and a committee chaired by Carl Sagan, and include music from Bach, Beethoven, Stravinsky, Chuck Berry, Louis Armstrong, and others. (Fun fact: the producer of the Golden Record,“ Timothy Ferris, is an award-winning science author who wrote the script for the Museum’s Space Show “Dark Universe.”)
The Record also features musical recordings from Senegal, Russia, Japan, and other countries. Carl Sagan, who worked on the project, stated that "the spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this ‘bottle’ into the cosmic 'ocean’ says something very hopeful about life on this planet.”

A sand pendulum that creates a beautiful pattern only by its movement.
But why does the ellipse change shape?
The pattern gets smaller because energy is not conserved (and in fact decreases) in the system. The mass in the pendulum gets smaller and the center of mass lowers as a function of time. Easy as that, an amazing pattern arises through the laws of physics.
what language do they speak at the center of the earth
an airplane is a ufo too unless you can identify what kind of airplane it is
Completely unrelated, but I wanted to show you these robots. Yes, these are not fish, these are robots - the future is now. Not to mention that they’re moving apparently randomly through a three-dimensional space, and not touching each other! That’s impressive.
