NASA – 5 Year Time-Lapse Of The Sun

 

   Here is the time-lapse video comprised of one still shot of the sun taken every eight hours from June of 2010 until February 2015 as recorded by the Solar Dynamics Observatory …

” The Solar Dynamics Observatory (SDO) celebrates its 5th anniversary since it launched on February 11, 2010. This time-lapse video captures one frame every 8 hours starting when data became available in June 2010 and finishing February 8, 2015. The different colors represent the various wavelengths (sometimes blended, sometimes alone) in which SDO observes the sun.

NASA – SDO: Year 5

” February 11, 2015 marks five years in space for NASA’s Solar Dynamics Observatory, which provides incredibly detailed images of the whole sun 24 hours a day. Capturing an image more than once per second, SDO has provided an unprecedentedly clear picture of how massive explosions on the sun grow and erupt ever since its launch on Feb. 11, 2010. The imagery is also captivating, allowing one to watch the constant ballet of solar material through the sun’s atmosphere, the corona.

  In honor of SDO’s fifth anniversary, NASA has released a video showcasing highlights from the last five years of sun watching. Watch the movie to see giant clouds of solar material hurled out into space, the dance of giant loops hovering in the corona, and huge sunspots growing and shrinking on the sun’s surface.

  The imagery is an example of the kind of data that SDO provides to scientists. By watching the sun in different wavelengths – and therefore different temperatures – scientists can watch how material courses through the corona, which holds clues to what causes eruptions on the sun, what heats the sun’s atmosphere up to 1,000 times hotter than its surface, and why the sun’s magnetic fields are constantly on the move.

  Five years into its mission, SDO continues to send back tantalizing imagery to incite scientists’ curiosity. For example, in late 2014, SDO captured imagery of the largest sun spots seen since 1995 as well as a torrent of intense solar flares. Solar flares are bursts of light, energy and X-rays. They can occur by themselves or can be accompanied by what’s called a coronal mass ejection, or CME, in which a giant cloud of solar material erupts off the sun, achieves escape velocity and heads off into space. In this case, the sun produced only flares and no CMEs, which, while not unheard of, is somewhat unusual for flares of that size. Scientists are looking at that data now to see if they can determine what circumstances might have led to flares eruptions alone.

  Goddard built, operates and manages the SDO spacecraft for NASA’s Science Mission Directorate in Washington, D.C. SDO is the first mission of NASA’s Living with a Star Program. The program’s goal is to develop the scientific understanding necessary to address those aspects of the sun-Earth system that directly affect our lives and society.

Sunspots, Which Can Harm Electronics On Earth, Are Half The Number Expected

” Scientists say that solar activity is stranger than in a century or more, with the sun producing barely half the number of sunspots as expected and its magnetic poles oddly out of sync.

The sun generates immense magnetic fields as it spins. Sunspots—often broader in diameter than Earth—mark areas of intense magnetic force that brew disruptive solar storms. These storms may abruptly lash their charged particles across millions of miles of space toward Earth, where they can short-circuit satellites, smother cellular signals or damage electrical systems.

Based on historical records, astronomers say the sun this fall ought to be nearing the explosive climax of its approximate 11-year cycle of activity—the so-called solar maximum. But this peak is “a total punk,” said Jonathan Cirtain, who works at the National Aeronautics and Space Administration as project scientist for the Japanese satellite Hinode, which maps solar magnetic fields.”

House Plan Would Protect Nation’s Electricity From Solar Flare, Nuclear Bomb

 

 

 

” Amid growing fears of a massive electromagnetic pulse hit from either a solar flare or a terrorist nuclear bomb, House Republicans on Tuesday will unveil a plan to save the nation’s electric grid from an attack that could mean lights out for 300 million Americans.”

 

 

” Dubbed the Secure High-voltage Infrastructure for Electricity from Lethal Damage Act, the legislation would push the federal government to install grid-saving devices such as surge protectors to protect against an attack.

Any EMP attack could be damaging, said Gaffney. He cited a new Lloyds of London report that determined that the area from Washington, D.C., to New York could be without electricity for up to two years in a major solar flare-up.”

 

 

” Gaffney told Secrets that there are some 300 huge electric transformers around the nation that control the grid and that have to be protected. “You are basically talking about surge protectors, of a somewhat exotic kind, but it is a means of interrupting the pulse,” he said.”
