A new view of two very well-known galaxies has revealed they are connected by faint, starless filaments of hydrogen gas, which trace back to a very high-speed intergalactic collision.

He used the 100-inch telescope on Mount Wilson in California - at the time, the largest telescope in the world - to measure the distances to other galaxies.

Meanwhile, astronomers in California were building the largest telescope in the history of the world - a new telescope on top of Mount Wilson, near Pasadena, with a mirror 100 inches (2.5 meters) across. In 1923, Edwin Hubble used this new telescope to prove that some of the nebulae, including the Sombrero, are actually other galaxies similar to our own Milky Way.
