The Hubble Space Telescope was invented by Lyman Spitzer, who first proposed the concept in 1946. Spitzer, a native of Toledo, Ohio, continued analyzing photos from the Hubble Space Telescope until his passing in 1997.
In 2012, a team of astronomers from the University of Pittsburgh announced that the Milky Way galaxy is aptly named thanks to its pure, milky white color, which the scientists described as resembling a fresh snowfall. The fact that Earth is located within the Milky Way galaxy has made the process of measuring the galaxy's color difficult; obstructions from things like dust and gas within the galaxy had previously made it hard for scientists to get a broad enough view of the Milky Way in order to determine its color.
Four layers of the earth's atmosphere containing various gases make up the composition of the sky. The layers of the atmosphere are divided into the troposphere, the stratosphere, the mesosphere and the thermosphere. The atmosphere's divisions occur according to temperature fluctuations.
