IRIS Provides Unprecedented Images of Sun


www.nasa.gov said:

The region located between the surface of the sun and its atmosphere has been revealed as a more violent place than previously understood, according to images and data from NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS.

Solar observatories look at the sun in layers. By capturing light emitted by atoms of different temperatures, they can focus in on different heights above the sun's surface extending well out into the solar atmosphere, the corona. On June 27, 2013, IRIS, was launched, to study what's known as the interface region a layer between the sun's surface and corona that previously was not well observed.

Solar Prominence - Sept 24, 2013

These movies show the highly dynamic motions in solar prominences. The movie on the right side shows the prominence motions of material at 65,000K. The vertical stripe in the center of the image is the entrance slit for the spectrograph part of the instrument. The left movie shows the resulting spectrum of material at 10,000k. The changing thickness of the line shows shows area of moving material and flows throughout the prominence and enables us to build up a 3 dimensional picture of prominence.

Solar Atmosphere Simulation - AGU Dec. 9, 2013

This movie shows a numerical simulation of a small area of the solar atmosphere at ~10,000K. Numerical models bridge the gap between IRIS observations and the physical mechanisms driving solar events and dynamics. By examining the similarities and differences between our models and the IRIS observations, we learn about the physics of the solar atmosphere.

This thread makes we want to watch Sunshine (2007) again. And also I think the sun is the solution to out world energy problems. But then how can we be controlled if every house could generate it's own energy.
