What makes Hubble so useful to astronomers?
Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.
What was Edward Hubble’s greatest contribution to astronomy?
Astronomer Edwin Hubble revolutionized the field of astrophysics. His research helped prove that the universe is expanding, and he created a classification system for galaxies that has been used for several decades.
What is Hubble’s greatest discovery?
What has Hubble found?
- Helped pin down the age for the universe now known to be 13.8 billion years, roughly three times the age of Earth.
- Discovered two moons of Pluto, Nix and Hydra.
- Helped determine the rate at which the universe is expanding.
What is Hubble’s purpose?
The purpose of the Hubble Space Telescope is to gather light from cosmic objects so scientists can better understand the universe around us. Hubble is in space, astronomers are on Earth.

What did Edwin Hubble study in astronomy?
Often called a “pioneer of the distant stars,” astronomer Edwin Hubble (1889–1953) played a pivotal role in deciphering the vast and complex nature of the universe. His meticulous studies of spiral nebulae proved the existence of galaxies other than our own Milky Way.
What things did Hubble discover?
What telescope feature is most important to astronomers?
The ability of a telescope to collect a lot more light than the human eye, its light-gathering power, is probably its most important feature. The telescope acts as a “light bucket”, collecting all of the photons that come down on it from a far away object.
Why is the Hubble telescope the most powerful?
The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry.
What is Chandra Mission?
NASA’s flagship mission for X-ray astronomy. NASA’s Chandra X-ray Observatory is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes.
How does the Hubble Space Telescope help scientists?
The Hubble Space Telescope helps scientists understand the universe and how planets, stars and galaxies form.
What is NASA Hubble?
The Hubble Space Telescope is a large telescope in space. NASA launched Hubble in 1990. Hubble is as long as a large school bus. It weighs as much as two adult elephants. Hubble travels around Earth at about 5 miles per second.
Why did Edwin Hubble want to become an astronomer?
Edwin Hubble walked away from a lucrative law career to pursue a career as an astronomer. He acknowledged that he may never become a famous astronomer but was willing to take the risk because he felt that understanding the galaxy was one of the most important things he could do.
When was the 20th anniversary of the Hubble Space Telescope?
The Hubble Space Telescope celebrated its 20th anniversary in space on April 24, 2010. To commemorate the occasion, NASA, ESA, and the Space Telescope Science Institute (STScI) released an image from the Carina Nebula.
