Solar Corona Revealed in Super-High-Definition

ScienceDaily (July 20, 2012) — Astronomers have just released the highest-resolution images ever taken of the Sun’s corona, or million-degree outer atmosphere, in an extreme-ultraviolet wavelength of light. The 16-megapixel images were captured by NASA’s High Resolution Coronal Imager, or Hi-C, which was launched on a sounding rocket on July 11th. The Hi-C telescope provides five times more detail than the next-best observations by NASA’s Solar Dynamics Observatory.

These photos of the solar corona, or million-degree outer atmosphere, show the improvement in resolution offered by NASA’s High Resolution Coronal Imager, or Hi-C (bottom), versus the Atmospheric Imaging Assembly on NASA’s Solar Dynamics Observatory (top). Both images show a portion of the sun’s surface roughly 85,000 by 50,000 miles in size. Hi-C launched on a sounding rocket on July 11, 2012 in a flight that lasted about 10 minutes. The representative-color images were made from observations of ultraviolet light at a wavelength of 19.3 nanometers (25 times shorter than the wavelength of visible light). (Credit: NASA)

“Even though this mission was only a few minutes long, it marks a big breakthrough in coronal studies,” said Smithsonian astronomer Leon Golub (Harvard-Smithsonian Center for Astrophysics), one of the lead investigators on the mission.

Understanding the Sun’s activity and its effects on Earth’s environment was the critical scientific objective of Hi-C, which provided unprecedented views of the dynamic activity and structure in the solar atmosphere.

MAR. 12: Massive triangle shaped hole in the Sun’s corona recorded by NASA

Don`t know what to say about this, it seems to have happened at the same time with the other solar event, posted here 2 posts back. You can see the other event at 1:20 in the lower left corner and pictures of this huge triangle on the SDO site…

NASA`s  explanation



new footage extracted from SDO archives from march 10 11 and 12 .

March 11:

March 12:



Apparently the NASA footage no longer displays march 11 and 12 so there is nothing to see there anymore. Check it out 

And the news hit daily mail


MARCH 13 UPDATE: It appears that “the object” was stationed there for many days  and after a quick google search i came up with this picture of the sun from march 10, 2012:



Straight from NASA.
