It is appropriate for grade levels 3-8‚ depending upon prior knowledge and interest level of student. Lesson Plan Purpose: Introduction to Astronomy The objective of this science lesson plan is to introduce the concepts of space‚ our solar system‚ galaxies and other celestial objects. Students will learn about the importance of space technology and space education. Students will use various space related activities to explore the basic concepts and to demonstrate their acquired knowledge. Students

and convinced astronomers that black holes exist. In particular‚ a technique used by astronomers to locate both stellar and super-massive black holes is to observe the motion of stars in the area around the supposed black hole.[4] Most stars in our galaxy are formed in groups of two or more stars‚ by observing the visible partner of a binary system‚ astronomers can effectively trace a black hole. Astronomers can calculate the mass of a black hole quite simply‚ using Keplar’s laws of motion‚ this is

foggy band of white light has been proven to be the home of our Solar System. There are so many different aspects that make the Milky Way so amazing. Its structure‚ age‚ surrounding galaxies and clusters‚ mythology‚ and existence of life throughout it make the Milky Way so great. The Milky Way is the immense‚ spiral galaxy which is home of our solar system with around 400 billion other stars and their planets‚ with thousands of nebulae and clusters. The milky way is actually a giant‚ with a mass of

Nebula is an interstellar cloud of dust‚ hydrogen‚ helium and other ionised gasses. The discovery of nebula goes back to the early 1600s. Nicolas-Claude Fabri de Peiresc discovered the Orion Nebula in 1610 using a refracting telescope. Nicolas-Claude Fabri de Peiresc used this telescope to observe the skies‚ for example‚ it was used to observe Jupiter’s moons as well as other aspects of space‚ including nebulae. The discovery of the Orion nebula was revolutionary. While it was Nicolas-Claude Fabri

Question Answers 1. What does Hubble’s law predict about the speed of a galaxy far away from the Milky Way compared to one that is closer? Hubble’s law predicted that galaxies were moving away from earth at a rate proportional to their distance from us. The farther away from the Milky Way a galaxy is‚ the larger the redshift is. The farther away a galaxy is‚ the faster it is moving away. Conversely‚ blueshifted galaxies‚ such as Andromeda‚ are moving closer to the Milky Way. 2. In a few sentences

be within our own galaxy. This illustrated that the Milky Way is just a small object within the universe. Later‚ by examining the light of distant galaxies‚ he showed that the universe is expanding‚ and that everything in it is moving away from everything else. In the early mid-1920s‚ Hubble began conducting new research with Milton Humason‚ on the galaxies’ spectral shifts and unique distances. He and Humason published their research in 1929‚ theorizing that red shifts in galaxies’ light emissions
