A star is born (IMAGE)
Caption
Visualization of gas in and around a Milky-Way-like galaxy (center) in today's Universe as predicted by a cosmological simulation run by the author. Dense, atomic and molecular hydrogen typically forms an extended disk, here seen in bluish-purple at the center of the image. Stars (white) form throughout the gas disk. Additional star formation may take place in satellite galaxies, here seen at the top right and bottom left positions. Hot, low density gas (green and red hues) can be found at large distances, out to the edge of the dark matter halo surrounding the main galaxy (white circle). The image also shows a large number of dark matter substructures (purple) most of which are devoid of gas and stars.
