NASA RELEASED SELECTIVE SHOTS OF SOHO'S 20 YEARS IN SPACE

NASA RELEASED SOHO'S TWENTY YEARS IN SPACE HIGHLIGHT VIDEO



Without a  doubt we use to listen from our parents to not look directly in sun as it can be harmful, but I think guys at NASA didn't took that advice seriously. Exactly 20 years ago today, they launched SOLAR AND HELIOSPHERIC OBSERVATORY  to do just that.
In that 12 years time, the orbiting spacecraft and its 12 sun-spotting instruments have provided NASA with a huge amount of information about our dear SUN.

      This video was released by NASA on Tuesday it gives details of some brilliant observations from SOHO, including an opening scene that shows what looks like flying saucers zipping around our sun. 
NASA heliophysicist and narrator of the video,said "Because they're so bright they overwhelm the detector in the electronics taking this image." That creates the long lines extending outward from their centers.
There are some tremendous images of sun-grazing comets (SOHO has seen over 3,000 of them); an explosive wave from the lower part of the corona; a complete solar rotation of approximately 28 days; and a few other impressive images.
Well NASA in description of this video said "After 20 years in space, ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, is still going strong. Originally launched in 1995 to study the sun and its influence out to the very edges of the solar system, SOHO revolutionized this field of science, known as heliophysics, providing the basis for nearly 5,000 scientific papers. SOHO also found an unexpected role as the greatest comet hunter of all time—reaching 3,000 comet discoveries in September 2015/When SOHO was launched on Dec. 2, 1995, the field of heliophysics looked very different than it does today. Questions about the interior of the sun, the origin of the constant outflow of material from the sun known as the solar wind, and the mysterious heating of the solar atmosphere were still unanswered. Twenty years later, not only do we have a much better idea about what powers the sun, but our entire understanding of how the sun behaves has changed."
Watch this exciting video above but as we know images and videos on blogspot are easily lost .well google should do something about it. if you are not able to see this video then click here
