Astronomical Clips

[Astronomy]

Hi, Dear astronomers

In this topic, We will share astronomical clips that we see in the internet

So, Please put them here with the source of the clip or the name of clip maker

[هانیه امیری]

Thank you dear astronomy for making this topic :)
Now I put the first clip for you

CCP: SpaceX Breakout Video

NASA and Space Exploration Technologies (SpaceX), of Hawthorne, Calif., signed a funded Space Act Agreement (SAA) in April 2011 for the company’s Dragon capsule. Under the $75 million agreement, NASA’s Commercial Crew Program (CCP) and SpaceX are working to outfit Dragon with life support systems and a launch abort system during Commercial Crew Development Round 2 (CCDev2). Through the development phases and certification processes, the agency is laying the foundation for future commercial transportation capabilities to low Earth orbit and the International Space Station. Ultimately, the goal is to lead to safe, reliable, affordable and more routine access to space so that commercial partners can market transportation services to the U.S. government and other customers. After a transportation capability is certified, NASA would be able to purchase transportation services to meet its International Space Station crew rotation and emergency return obligations.

The interior of Mars holds vast reservoirs of water, with some spots apparently as wet as Earth's innards, scientists say.

The finding upends previous studies, which had estimated that the Red Planet's internal water stores were scanty at best — something of a surprise, given that liquid water apparently long ago.

"It’s been puzzling why previous estimates for the planet’s interior have been so dry," co-author Erik Hauri, of the Carnegie Institution of Washington, said in a statement. "This new research makes sense and suggests that volcanoes may have been the primary vehicle for getting water to the surface."



I should say that my friend parnia shokri put this clip on beyondsky.ir and the source of this clip is : http://www.space.com

All 135 Space Shuttle Launches at Once
by Nancy Atkinson on July 6, 2012

4510 (http://forum.avastarco.com/forum/%3Ciframe%20src=%22http://player.vimeo.com/video/27505192%22%20width=%22400%22%20height=%22300%22%2 0frameborder=%220%22%20webkitAllowFullScreen%20moz allowfullscreen%20allowFullScreen%3E%3C/iframe%3E)

We’re not sure how we missed this when it came out last year, but this incredible video shows all 135 launches of the space shuttle program at once. Creator McLean Fahnestock calls it “The Grand Finale” and rightly so. A great display of “fireworks” and a wonderful homage to the legacy of the space shuttles.

The one launch failure, Challenger on STS-51-L does stand out in this video and the words “obviously a major malfunction” will always linger. But the drive to keep striving for the heavens will always be there.

Hi, Dear astronomers :welcome:
This video is about Raining Loops on the Sun
On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and a dazzling magnetic display known as coronal rain. Hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, and outlining the fields as it slowly falls back to the solar surface
