Most detailed pic of a sunspot ever taken


NJIT Distinguished Professor Philip R. Goode and the Big Bear Solar Observatory (BBSO) team have achieved "first light" using a deformable mirror in what is called adaptive optics at Big Bear Solar Observatory (BBSO). Using this equipment, an image of a sunspot was published yesterday on the website of Ciel et l'Espace, as the photo of the day: http://www.cieletespace.fr/node/5752

"This photo of a sunspot is now the most detailed ever obtained in visible light," according to Ciel et l'Espace. In September, the publication, a popular astronomy magazine, will publish several more photos of the Sun taken with BBSO's new adaptive optics system.

Goode said that the images were achieved with the 1.6 m clear aperture, off-axis New Solar Telescope (NST) at BBSO. The telescope has a resolution covering about 50 miles on the Sun's surface.

The telescope is the crown jewel of BBSO, the first facility-class solar observatory built in more than a generation in the U.S. The instrument is undergoing commissioning at BBSO.

4. What a different world we'd be living in under Ghandi's leadership.
All truths uttered at different times by different Christians, but how wonderful it would have been had a Pope composed that epigrammatic compendium, and raised Cain about its particular applicability to the West.

Strange how the most seminal and significant truths seem to be expressible in a few words or mathematical symbols.

10. Is there anything you do know, old chap? Don't answer that. It was rhetorical. We're
all too aware of your, seemingly, permanently confused condition.

17. Funny how subjective the phenomena is ...
> La température y est d'environ 3600°C. Tout autour, la mosaïque de petites
> cellules est ce qu'on appelle la granulation (température : environ 5800°C).

The "black" bit of the sunspot is about 3,600°C whilst the surrounding
"bright" cells are about 5,800°C.

3,600°C makes it look "dark"!

:wow:

18. "3,600°C makes it look "dark"!" Ah, only in comparison to the surrounding material.
If you just looked at the isolated sunspot itself, while screening out the surrounding material, the sunspot would be white hot.
