The discovery of Hubble's law is attributed to work published by Edwin Hubble in 1929, [2] [3] [4] but the notion of the universe expanding at a calculable rate was first derived from general relativity equations in 1922 by Alexander Friedmann.
The Hubble telescope captures the brightest galaxies ever seen, thousands of galaxies act like lenses that magnify light, making them appear super bright. Hubble Telescope reveals new discovery of ...
The law states that the greater the distance between any two galaxies, the greater their relative speed of separation. In 1929, Edwin Hubble discovered that most of the universe was expanding and moving away from everything else. If everything is moving away from everything else, then it should be thought that everything was once closer together.
"Hubble's Heritage" – In 1929, astronomer Edwin Hubble made one of the greatest discoveries in the history of science—the expansion of the universe. To honor this king of cosmology, an orbiting observatory named the Hubble Space Telescope was launched in 1990 after years of research and delay. Hubble's Heritage takes a closer look at this ...
The discoveries of Edwin Hubble and Milton L. Humason are described. The episode moves further into ideas about the structure of the Universe, such as different dimensions (in the imaginary Flatland and four-dimensional hypercubes), an infinite vs. a finite universe, and the idea of an oscillating Universe (similar to that in Hindu cosmology).
The discovery of the huge radio jet is providing a window into the early days of the universe, shedding light on when the first jets formed and how they shaped galaxies over time. Finding an ...
