Today in science: Spacecraft destroys sundog | Earth

On this date in 2010, the most beautiful launch ever! I came across this image and the video through a post on Google+ and I was interested when I saw a quote from the person who runs the best world site for sky optical, Les Cowley of the site Atmospheric Optics. The story began with the launch in 2010 of NASA's Solar Dynamics Observatory (SDO), one of many observers watching our sun. It seems that when the SDO took off from Cape Canaveral February 1

1, 2010, in its mission to observe the sun, it first destroyed a sundog in the Earth's atmosphere – in the process bringing to light a new form of halo of ice – and teaching those who love and study the optics of the sky new things about how the waves interact with the clouds.

The video above shows the launch of the SDO in 2010 through an Atlas V rocket Watch it now, and turn up the volume to hear people rejoice when the spaceship passes through the atmosphere has destroyed the sundog – which is a bright spot in the sky, formed by the refraction of sunlight through flat-shaped ice crystals, which descend from the sky like leaves moving from trees. If you have to, look at it twice to see the luminous column of white light that appears next to Atlas V.

Les Cowley explained in this 2011 post at Science @ NASA:

When the rocket penetrated the cirrus clouds, shock the waves rippled through the cloud and destroyed the ice crystals. This extinguished the sundog.

The destruction of the sundog was understood. The events that followed were not. Cowley said:

A bright column of white light appeared near Atlas V and followed the rocket upward into the sky. We had never seen anything like it.

Cowley and colleague Robert Greenler at the beginning could not explain this column of light. Then they realized that flat-shaped ice crystals were organized by the Atlas V-wave. Cowley explained:

The crystals are tilted between 8 and 12 degrees. Then they turn so that the main crystalline axis describes a conical movement. Toy tops and gyroscopes do it. The earth does once every 26,000 years. The motion is ordered and precise.

Love it!

Conclusion: When NASA's Solar Dynamics Observatory took off from Cape Canaveral February 11, 2010, in its mission to observe the sun, first destroyed a sundog in the Earth's atmosphere – in the process which brings to light a new form of aura of ice – and teaches those who love and study the optics of the sky new things about how the waves interact with the clouds.
