... 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. ...

2.5Г-1021 cm-2) have associated dust emission. ... We estimate dust masses of ~104-106 Msolar for the M81 dwarf galaxies, resulting in an average dust-to-gas ratio (Mdust/MHI) of ~3Г-10-4 (1.5Г-10-3 if only the H I that is associated with dust emission is considered); this is an order of magnitude lower than the typical value derived for the SINGS spirals. ... However, the average 70/160 О?m ratio in the sample dwarf galaxies is higher than what is found in the other galaxies of the SINGS sample. ...
