... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...

. You can leave text in its present location and move a copy of it to a different location. This is useful when you have a special paragraph that you want to repeat in a number of locations. To copy a block of text: . 1. Define the 'region' . 2. Type the M-C instruction to 'copy' the 'region'. 3. Move the cursor to the place where you want the copied text to go. 4. Type ^Y to 'yank' the text. A copy of the text moves from the 'kill' buffer and appears at its new location.
