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 the major advantage of orbiting telescopes?
The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.
Why is the Hubble space Telescope so special?
Hubble’s incredible reach — made possible by the fact that its sight was not impaired by the Earth’s atmosphere — allowed astronomers to get closer looks at space phenomena like never before, watching stars and planets as they form, examining exoplanets and capturing the power of cosmic impacts.
What are the advantages and disadvantages of the Hubble telescope?
- The earth’s atmosphere. The first advantage?
- The detail is absolutely extraordinary.
- It points to the potential of the space program.
- Operating in space.
- Time consuming.
- Expensive.
- Repairs are difficult.
- Out of date.
What three things did the Hubble space Telescope accomplish?
- 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.
Is Hubble still useful?
NASA anticipates that Hubble will last for many more years and will continue making groundbreaking observations , working in tandem with other space observatories including the James Webb Space Telescope to further our knowledge of the cosmos. Launched in 1990, Hubble has been observing the universe for over 31 years.
Is Hubble visible from Earth?
Hubble is best seen from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south . This is because Hubble’s orbit is inclined to the equator at 28.5 degrees. ... In contrast, the ISS passes over much more of the Earth because its orbit has a higher inclination at 51.6 degrees.
How far away from Earth will the Webb telescope be placed?
This allows the satellite’s large sunshield to protect the telescope from the light and heat of the Sun and Earth (and Moon). Webb will orbit the sun 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2.
What are the disadvantages of space telescopes?
Disadvantages. Space telescopes are much more expensive to build than ground-based telescopes . Due to their location, space telescopes are also extremely difficult to maintain. The Hubble Space Telescope was serviced by the Space Shuttle, but most space telescopes cannot be serviced at all.
Why dont we just image the sky with telescopes?
The Development of Telescopes
Most of the universe is invisible to us because we only see the visible light portion of the electromagnetic spectrum .
How far can the Hubble telescope see?
The farthest that Hubble has seen so far is about 10-15 billion light-years away . The farthest area looked at is called the Hubble Deep Field.
Why do astronomers want telescopes in space?
Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe . ... Many of these types of light (such as x-rays, gamma-rays, most ultraviolet, and infrared) can only be studied from space because they are blocked by our atmosphere.
How has the Hubble telescope benefited society?
Hubble has helped scientists learn about our solar system . ... The telescope has helped scientists understand how planets and galaxies form. Galaxies contain billions of stars. A picture called “Hubble Ultra Deep Field” shows some of the farthest galaxies ever seen.
Did Hubble discover God?
The Hubble telescope has scientifically confirmed the power Isaiah wrote about, and is now revealing a Grand Drama that takes us to the core of our very existence!
How many galaxies are there?
The deeper we look into the cosmos, the more galaxies we see. One 2016 study estimated that the observable universe contains two trillion—or two million million —galaxies. Some of those distant systems are similar to our own Milky Way galaxy, while others are quite different.
Can we see other galaxies?
Answer: Yes, you can see a few other galaxies without using a telescope! ... The nearby Andromeda Galaxy , also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.
