What are important finds of the Hubble Space telescope?

What are important finds of the Hubble Space telescope?

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. Discovered that nearly every major galaxy is anchored by a black hole at the centre.

Why is the telescope important?

The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.

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.

Why was the telescope such an important invention?

The invention of the telescope played an important role in advancing our understanding of Earth’s place in the cosmos. Early telescopes were primarily used for making Earth-bound observations, such as surveying and military tactics.

What is the most important feature of a telescope?

Aperture: A Telescope’s Most Important Feature The most important characteristic of a telescope is its aperture — the diameter of its light-gathering lens or mirror, often called the objective. Look for the telescope’s specifications near its focuser, at the front of the tube, or on the box.

Why is space discovery important?

Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets.

How Hubble and Chandra telescopes help scientists?

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 was the purpose of the Chandra mission?

Mission Overview 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.

What is the main advantage of a reflecting telescope design?

The main advantage is reflector telescope can escape from chromatic aberration because wavelength does not effect reflection. The primary mirror is very stable because it is located at the back of the telescope and can be support in the back. More cost effective than refractor of similar size.

What are the two most important functions of a telescope?

The most important functions of a telescope are (1) to collect the faint light from an astronomical source and (2) to focus all the light into a point or an image.

Why is the Hubble Telescope better than other telescopes?

Why is Hubble able to see so much better than telescopes on Earth? Because it is above the Earth’s atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So Hubble’s images are much sharper than those from other telescopes.

What does the Hubble Space Telescope really see?

Hubble is a telescope that orbits Earth. Its position above the atmosphere gives it a view of the universe that typically far surpasses that of ground-based telescopes. Thirty years since launch, the Hubble Space Telescope continues its role at the forefront of astronomy, ranging from our own Solar System to the high-redshift universe.

What is so special about the Hubble telescope?

The Hubble Space Telescope was launched on the Space Shuttle on April 24, 1990. 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. These clouds block the view of the Earth-based telescopes which scientists have used for many years.

What are some interesting facts about the Hubble telescope?

16 Interesting Facts About the Hubble Space Telescope. The Hubble Space Telescope is 43.5 feet long and 14 feet wide. It weighs more than 11,000 kilograms and costs around 1.5 billion dollars. Hubble is nearly the size of a large school bus, but can easily fit into the cargo bay of a space shuttle.
