Why Are Most Stars On The Main Sequence? So, broadly speaking, there are so many stars on the main sequence – compared to elsewhere in the H-R diagram – because stars spend much more of their lives burning hydrogen in their cores than they do producing energy in any other way! Why are about 90%
What Did The Hubble Do? Hubble has helped scientists learn about our solar system. The telescope observes comets and planets. Hubble even discovered moons around Pluto that had not been seen before. The telescope has helped scientists understand how planets and galaxies form. What is Hubble most famous for? Edwin Hubble, for whom the Hubble
How Did Georges LeMaitre Come Up With The Big Bang Theory? In 1927, the Belgian Catholic priest Georges Lemaitre proposed an expanding model for the universe to explain the observed redshifts of spiral nebulae, and calculated the Hubble law. He based his theory on the work of Einstein and De Sitter, and independently derived Friedmann’s
Did The Ancient Greeks Know About Other Planets? It is hence pure conjecture that Greeks of the 6th and 5th centuries BC were aware of the planets and speculated about the structure of the cosmos. Also, a more detailed description about the cosmos, Stars, Sun, Moon and the Earth can be found in the Orphism,
Why Is Kepler Important? Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion. He also did important work in optics and geometry. How did Kepler change the view of the universe? He regarded them
What Was Uranus Original Name? Name and Meaning: As he lived in England, Herschel originally wanted to name Uranus after his patron, King George III. Specifically, he wanted to call it Georgium Sidus (Latin for “George’s Star”), or the Georgian Planet. What does the name Uranus mean? The Romans named the five planets closest to
What Is ALMA Telescope Used For? The most powerful Earth observatory in history ALMA is used to observe light from space in millimetric and submillimetric wavelengths. ALMA is being used to study planetary systems that orbit distant stars. Millimeter/submillimeter-wave observations can aid the search for extrasolar planets in many ways. How many telescopes does ALMA
Who Named Mercury And What Does It Mean? Mercury is named after the messenger for their gods. The Roman Mercury had wings on his helmet and shoes. He could travel very quickly from place to place. The planet Mercury moves quickly around the sun. That is how it got its name. Who named Mercury planet?
How Did Cecilia Helena Payne-gaposchkin Discover The Composition Of The Universe? After two years of unremitting effort, Payne built a temperature scale for stars versus their absorption intensities allowing her to calculate the abundances of chemical elements. She was amazed when she discovered: regardless of spectral type, stars all had similar compositions. What new at
Why Is The Hubble Space Telescope So Special? Hubble’s incredible reach — made possible by the fact that its sight was not impaired by the Earth’s atmosphere — allowed astronomers to get closer looks at space phenomena like never before, watching stars and planets as they form, examining exoplanets and capturing the power of cosmic
