A recent NASA/ESA Hubble Space Telescope image of part of NGC 7023, or the Iris Nebula, highlights a perfect dust laboratory in the sky.
This close-up of an area in the northwest region of the large Iris Nebula seems to be clogged with cosmic dust. With bright light from the nearby star HD 200775 illuminating it from above, the dust resembles thick mounds of billowing cotton.
It is actually made up of tiny particles of solid matter, with sizes from ten to a hundred times smaller than those of the dust grains we find at home. Both background and foreground stars are dotted throughout the image. (Read more...)
After the evaluation of the course done by the teachers, the course continued with a general lecture with the title "Into the future. The next generation telescopes and their impact on science education", presented by Claus Madsen.
Claus Madsen enphatized the idea that "the future is here today" when he talked about all the science that can be made using the ESO's VLT images. He also talked about the ALMA project and of some projects for the future namely the ELT. The general lecture was followed by the closing session were the importance of the Summer Schools in the history of EAAE was summarized.
