How did Edwin Hubble change the world?

He revolutionized astronomy The discovery of the Cepheid variable allowed Hubble to deduce that the Andromeda Nebula was not a nearby cluster of stars, but an entirely different galaxy. By the 1930s, most astronomers had been convinced that the Milky Way galaxy was but one of millions in the universe.

How did Hubble make such an important discovery?

This means telescopes like Hubble act like time machines, enabling us to study the history of our Universe. Here are some of its major contributions to science: Helped determine the rate at which the universe is expanding. Discovered that nearly every major galaxy is anchored by a black hole at the centre.

Why was the Hubble in space necessary?

Hubble was designed as a general purpose observatory, meant to explore the universe in visible, ultraviolet and infrared wavelengths. To date, the telescope has studied more than 40,000 cosmic objects, providing views astronomers were unable to capture from the ground.

What is special about Hubble?

It is a very special telescope which orbits far above the Earth. Hubble allows us to see objects more clearly because it is above the clouds in Earth’s atmosphere. Hubble is not only a powerful telescope, but it also carries cameras which allow scientists on Earth to see objects billions of light-years away.

How did Edwin Hubble improve our understanding of the universe?

Hubble found that by timing a star’s fluctuations of luminosity, he could measure its distance from Earth. With this technique, Hubble proved that the nearby Andromeda nebula was not a gas cloud in our own galaxy, but was actually a separate galaxy. His announcement literally changed how we see the universe.

What did Edwin Hubble discovered that changes your view in universe?

The Expanding Universe As Hubble continued his study, he made another startling discovery: The universe is expanding. In 1929 he determined that the more distant the galaxy is from Earth, the faster it appears to move away. Known as Hubble’s Law, this discovery is the foundation of the Big Bang theory.

How did Chandra telescope help scientists?

The Chandra X-ray Observatory, which was launched by Space Shuttle Columbia in 1999, can better define the hot, turbulent regions of space. This increased clarity can help scientists answer fundamental questions about the origin, evolution, and destiny of the universe.

How was Hubble important to our understanding of galaxies?

Edwin Hubble was important in advancing our understanding of galaxies. In the 1920s, he discovered that there are other galaxies in the universe. Hubble was also able to classify spiral galaxies based on their tightness and nuclear bulge size.

Was the Hubble telescope successful?

In the end, the mission was a complete success. The astronauts installed two new instruments, fixed two broken instruments, and installed new batteries, new gyroscopes and a new scientific computer, to prolong Hubble’s life. Today, it continues to be one of the most powerful, most in-demand telescopes in the world.

Is Hubble still useful?

NASA has returned the science instruments on the Hubble Space Telescope to operational status, and the collection of science data will now resume. Thanks to their dedication and thoughtful work, Hubble will continue to build on its 31-year legacy, broadening our horizons with its view of the universe.”

What did Edwin Hubble discover about the universe for kids?

He discovered the existence of galaxies beyond the Milky Way and the fact that the universe is constantly expanding. The Hubble Space Telescope, which is a large space telescope that takes pictures of planets, stars, and galaxies, was named for Edwin Hubble.

What is the #1 cool fact about the Chandra?

At 45 feet long, Chandra is the largest satellite the shuttle has ever launched. At 45 feet long, Chandra is the largest satellite the shuttle has ever launched. How smooth are Chandra’s mirrors? If Colorado were polished to the same relative smoothness as Chandra’s mirrors, Pikes Peak would be less than one inch tall!
