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

The great astronomer Edwin Hubble was able to see for the first time that the outer spiral arms of the Andromeda galaxy contained individual stars. Theses appeared similar to many found in the Milky Way‚ but were much fainter. Hubble located three novae. One of these novae‚ however‚ turned out to be a Cepheid variable‚ a star that changes predictably in brightness. This Cepheid‚ and others subsequently discovered in the Andromeda Nebula‚ enabled Hubble to prove that the Nebula was not

Over 100 years ago‚ if you asked a scientist about the universe they would say it’s eternal‚ infinite and stable. No beginning and no end. So even asking the question about the origins of the universe was infinitesimally small. But at the start of the 20th century‚ that began to change. New findings stirred the old beliefs and paved the way for questions about where the universe came from. One observation altered our idea about the true scale of the universe. It started with a mystery in the sky

Steve wozniak with Steve jobs and Ronald Wayne.Their inventions and machines are credited with contributing significantly to the personal computer revolution of the 1970’s. Edwin Hubble changed the way we see our universe! By demonstrating the existence of galaxies other than our own‚ the milky way. He is also famous for his Hubble LAW‚ and helped establish that the universe is expanding. Critical thinking qualities : 1. realistic 2. facts‚ apply

3559) Edwin Hubble was one of the first people to actually realise what a galaxy is‚ the measurement of the “Hubble Tuning Fork” Classification scheme shows how round or rightly wound their “arms” are. E0 means that an elliptical galaxy is extremely round‚ whilst E7 is flat. However not all galaxies can be classified in this manner as there are several irregular shapes usually caused by 2 different galaxies having collided or are being influenced by the other’s gravitational force.

1.0 Introduction The Hubble Space Telescope was created by and named after astronomer Edwin P. Hubble. He was known for his creation of Hubble’s Law which is used to calculate the rate at which the universe is expanding. He is also known for his discovery of the galaxies that are outside the Milky Way. The Hubble Space Telescope is a large telescope that is placed in orbit around the earth. Scientists have figured out that by placing a telescope in space‚ putting it outside of earth’s atmosphere

Compare the views of Hubble and Friedman about the expansion of the universe: Edwin Hubble’s observation In 1929‚ Edwin Hubble announced that his observations of galaxies outside our own Milky Way showed that they were systematically moving away from us with a speed that was proportional to their distance from us. The more distant the galaxy‚ the faster it was receding from us. The universe was expanding after all‚ just as General Relativity originally predicted! Hubble observed that the light

The use of the term multiverse or its other moniker parallel universe‚ has been used in cosmology‚ physics‚ and philosophy to perhaps more prominently in science-fiction literature and movies for decades. Ever since Edwin Hubble discovered that the universe is expanding in the 1920s‚ there have been questions regarding the possibility of there being more than one universe. However‚ there has been no evidence to support the existence of multiverse. Interestingly‚ despite
