On 21st August, a total solar eclipse will be seen from Oregon to South Carolina. This is an once-in-a-lifetime event in the United States for millions who will experience that happens, for a small time, when the day becomes night. The last time such a coast-to-coast view was experienced by the U.S to be a total solar eclipse was around 100 years ago.
Here are few things important outlined.
- An eclipse refers to an object blocking the light from another object. It means it forms a cosmic shadow.
- This shadow blocks the sunlight and scientists can see the light blocking across giant gas clouds, planets and more.
- This is not the light we can see directly. In fact, microwaves, radio waves, ultraviolent, infrared light, gamma rays and x-rays are few different light flavors that are beyond the reach of humans to detect.
- We are familiar of the sun light that is the nearest star producing light. Though there are radio waves to gamma producing light.
- Actually shadows can happen with all the different light types and scientists use these shadows to study cosmic objects different kinds.
- The fact is that light travels faster and it means it takes nearly 8 minutes for light from the sun to reach our earth.
- In fact, most objects from our planet and also the celestial objects such as the Moon, do not give away their visible light. They reflect and absorb light from a source like our sun or a light bulb.
- The light path can be bent and is responsible for colorful rainbows to red sunset color.
These are few things to know before the solar eclipse when sun goes dark temporarily.
