showing a star changes over the course of the time. Also‚ it relates to the mass‚ ages‚ sizes of the stars. Also‚ I used the Hertzsprung-Russell (H-R) diagram concept to classify the stars and find the Main Sequence. When the stars are hotter and more luminous‚ they main sequence tends to follow a band going from the bottom right to the top left at the diagram. This concept can help to classify the stars‚ such as main sequence stars‚ red giant‚ blue giant‚ supergiant stars‚ virtually dead stars‚ and binary

Stars moving away from us are red shifted (light of longer wavelength) while stars movingtowards us are blue shifted (shorter wavelength) 4.- 5.Use a model to describe the expanding universe. Hubble’s law states the further away stars and galaxies were‚ the faster they were going.Thefact that most galaxies are moving away suggests that the universe is expanding

Exoplanet or extrasolar planet that orbits a star other than earth’s sun was observed from the High Accuracy Radial velocity Planet Searcher instrument‚ or HARPS. By studying the properties of all the alien planets detected by HARPS so far‚ Astronomers found that approximately 40 percent of stars similar to the sun is host to at least one planet that is less massive than the gas giant Saturn. In other words‚ approximately 40 percent of sunlike stars have at least one low-mass planet orbiting around
