Black hole - Study guides, Class notes & Summaries

We have learned that the centre of the milky way contains a very massive black hole. We developed this understanding by: - Monitoring the orbital motions of many individual stars in the very central parts of the Milky Way If the sun were to be squashed down small enough to become a black hole, then: - The planets in the solar system would orbit the Sun in unchanged fashion (but would receive no light from it) The first stellar mass black hole identified, Cygnus X-1, was found in 1973. The n...

A map is defined as a graphic representation of a portion of the Earth's surface drawn to scale, as seen from above. It uses colors, symbols, and labels to represent features found on the ground. -The ideal representation would be realized if every feature of the area being mapped could be shown in true shape. -The purpose of a map is to provide information on the existence, location, and distance between ground features, such as populated places and routes of travel and communication. I...
