NEW STUDENT JOINS LAB
The Sun Now - 304Angstroms
This wavelength is especially good at showing areas where cooler dense plumes of plasma (filaments and prominences) are located above the visible surface of the Sun. Many of these features either can't be seen or appear as dark lines in the other channels. The bright areas show places where the plasma has a high density.
The daily video of the sun is a near real time view of our nearest star from a NASA satellite called the Solar Dynamics Observatory. This video may take a moment to load so please be patient. It is after all, coming to you from ~35800km above the Earths surface.
