The idea of an expanding universe is a key underpinning of the Big Bang Theory.

Its main purpose was to figure out a distance scale of the Universe (how big it is) and where the elements present in space came from. Hubble also demonstrated that galaxies farther away from us are receding faster than those nearby – a fundamental observation now known as Hubble’s Law. The Hubble Space Telescope was launched in 1990, taken to space in the cargo bay of the space shuttle Discovery. This phenomenon, known as redshift, reveals that the farther a galaxy is away from us, the redder its light will appear. It became apparent that our universe was ceaselessly expanding outward, and all galaxies housed within it were moving away from one another. By studying the light emitted from various galaxies, Hubble discovered that the light appeared displaced toward the red end of the spectrum. Contrary to the previously held view of a static universe, Hubble ultimately proved that galaxies are, in fact, moving away from us. This star allowed Hubble to calculate a reliable distance to Andromeda, proving that it was a separate galaxy outside our Milky Way.By 1929, Hubble had completely reimagined our place in the universe not only was it home to millions of other galaxies, but the universe itself was expanding as well. Edwin Hubble seated at the 100-inch reflecting telescope at the Mount Wilson Observatory in California. His observations brought these fuzzy patches into focus, and in the process transformed the field of cosmology. He crossed out the 'N' and wrote 'VAR,' for variable. Hubble used the 100-inch telescope to observe faint, fuzzy, cloud-like patches of light broadly labeled nebulae. Later, Hubble realized that the nova at top right was actually a Cepheid variable. An arrow points to a copy of Hubble's image of Andromeda, which was made on a 4-inch-by-5-inch (approximately 10 x 13 cm) glass plate and dated 6 October 1923.Įdwin Hubble originally identified three novae, a class of exploding star, by writing 'N' next to each object.

The large white box outlines the region imaged by astronomer Edwin Hubble, who used the 100-inch Hooker telescope, the most powerful telescope of that era. Astronomers use them to calculate how far away they are from Earth.

Cepheid variables are pulsating stars that brighten and fade in a predictable pattern. T-shirts, posters, stickers, home decor, and more, designed and sold by independent. The white circle at lower left identifies Hubble variable number one, or V1, the Cepheid variable star discovered by astronomer Edwin Hubble in 1923. High quality Edwin Hubble Telescope-inspired gifts and merchandise. The snapshot is blanketed with stars, which look like grains of sand.

Among its famous observations is the Hubble Ultra Deep field, the deepest image of the universe ever made at visible and near-infrared wavelengths, and revealed over 10,000 galaxies in a small patch of sky. An arrow points to the Hubble image, taken by the Wide Field Camera 3. The telescope has observed some of the farthest galaxies ever seen, thanks to its iconic deep field imagery. The tiny white box just above centre outlines the Hubble Space Telescope view. Andromeda is a Milky Way neighbor and resides 2 million light-years away. Hubble showed that some of the numerous distant, faint clouds of light in the universe were actually. In the 1920s, making use of relationships established by Henrietta Swan Leavitt, Dr. The pancake-shaped disk of stars, gas, and dust that make up the Andromeda galaxy, or M31, is shown in the image at left. The Hubble Space Telescope was named after astronomer Edwin Powell Hubble (18891953), who made some of the most important discoveries in modern astronomy. Views of a famous pulsating star taken nearly 90 years apart and a portrait of its galactic home are shown in this image collection. The complete timeline below describes Hubble’s history from the first proposal of a space telescope by Lyman Spitzer in 1946, through the completion of Hubble’s five servicing missions in the 1990s and 2000s, and to many of the significant observations and discoveries Hubble has made during its years in orbit.
