There have been some really awesome pics of the sun lately. Like the combined view from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, overlaid on a picture taken by NASA's Solar Dynamics Observatory (SDO). This is the first picture of the sun taken by NuSTAR
This article from News Ledge details the road to the 100th Million Photo of the Sun...
The AIA takes 57,600 images of the sun everyday. That’s nearly as many Kim Kardashian images taken everyday.
The Solar Dynamics Observatory has been giving scientists an in-depth look of the sun since February 2010. These include insights about solar flares, the sun’s magnetic field and the temperature differences between the corona and the sun’s surface.
In celebration of this milestone, Dean Pesnell (SDO project scientist) and Karely Schrijver (AIA principal investigator) picked 12 of their favorite images from the SDO. I’m going to highlight a couple of them. Check out the rest here.
This image shows the power of the SDO and the AIA. Scientists can observe the entire sun in a variety of wavelengths. The image below shows all the different wavelengths the SDO can see the sun in.
Man, the Sun loves the spotlight more than celebrities. NASA recently released the 100-millionth image of the sun. The milestone image was snapped in the early afternoon on January 19th by a telescope on NASA’s Solar Dynamics Observatory.
The instrument used to capture the image is called the Atmospheric Imaging Assembly (AIA). It actually uses four telescopes to snap 8 images of the sun every 12 seconds. These images are captured through a variety of wavelengths (10 total).
Check out the partial solar eclipse in the image below. Sometimes the moon crashes SDO’s viewing party. You can see some of the moon’s mountain ridges, especially on the bottom left part of the moon.
Take the 100-millionth image posted above. That image was taken at a wavelength of 193 angstroms. While the image below was taken at 335 angstroms.
