Astronomers suspect that a galaxy’s type can be affected both by the conditions in the protogalactic cloud from which it forms ("initial conditions") and by later interactions with other galaxies. each item below describes either a condition in a protogalactic cloud or a later interaction. match these items to the galaxy type you would expect to form as a result. spiral galaxy or elliptical galaxy? 1. protogalactic cloud has high angular momentum2. a galaxy collision strips away gas3. protogalactic cloud rotates very slowly4. most protogalactic gas settles into a disk5. protogalactic cloud has high density6. stars form rapidly as the protogalactic cloud shrinks

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
