Earth Image Archive

This is a picture of the Earth's magnetic field and the Van Allen Belts. The Van Allen Belts are two layers where the atomic particles are trapped and the magnetosphere is dense. This is another image of the magnetosphere. This infrared image of the Earth was taken by the GOES 6 satellite on September 21, 1986. This photo was taken in December 1972 by the Apollo 17 crew. Image of Earth. This image of the Earth was taken by the Galileo spacecraft at about 6:10 a.m. This is an image of the Earth's Western Hemisphere. This is a rendered image of Earth. This image shows the divisions of the Earth's interior. This is an image of Antarctica taken by Galileo on December 8, 1990. This is an image of an Antarctic Surface Plot of weather. This United States is a mosaic prepared by using 16 images from the Advanced Very High Resolution Radiometer (AVHRR) sensors on the meteorological satellites NOAA-8 and NOAA-9.

Max-Born-Institut, Aktuell

21st February 2014 The multi-electron dynamics in atoms and molecules is a great challenge in contemporary quantum physics, with implications from chemical reactions to superconductivity. A classical example, much investigated over the last two decades, has been the so-called "nonsequential" double ionization (NSDI) of atoms by an intense laser field, where "nonsequential" means that ionization does not happen one step at a time, viz. ionization of the atom later followed by ionization of the positively charged ion, but rather in one combined process. A precondition for this to happen is electron-electron correlation. Ionization appears as a paradigmatic quantum process (according to some textbooks proving the quantum nature of light).

If you are reading this you are probably an admirer of the beautiful color images produced year after year by the Hubble news team.

Until now it was difficult for anyone other than a trained astronomer to create images like these from the original grayscale Hubble data. That’s because Hubble data is stored in a special “flavor” of the FITS (Flexible Image Transport System) data format that has been nearly impossible to open in common photo editing software, such as Adobe Photoshop. Now, thanks to a collaboration between ESA, ESO and NASA, a free software plugin is available that enables anyone with Adobe Photoshop CS (and, to a limited degree, other versions of Photoshop and certain other image editors) to open Hubble (and other) FITS data and process it to create finished, conventional-format digital images. The FITS Photoshop Liberator is available for download from this ESA Space Telescope site.
