What makes the Hubble Space Telescope unique?

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.

Why is the Hubble space telescope so unique?

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 makes the Hubble telescope different?

What Makes Hubble Different From Telescopes on Earth? 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 is fascinating about the Hubble space telescope?

Hubble orbits the Earth at a cruising speed of 17,000 miles per hour, and takes 15 minutes to rotate 90 degrees. Hubble has observed locations more than 13.4 billion light years away, meaning it has seen light that existed in the universe 13.4 billion years ago.

Why is the Hubble telescope better?

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.

Why is the Hubble Space Telescope considered the most significant advancement in astronomy since Galileo’s first optical telescope?

Hubble’s launch and deployment in April 1990 marked the most significant advance in astronomy since Galileo’s telescope. Thanks to five servicing missions and more than 25 years of operation, our view of the universe and our place within it has never been the same.

What flaw did the Hubble Space Telescope have?

spherical aberration

It suffered from spherical aberration—not all portions of the mirror focused to the same point. The mirror’s shape was off by less than 1/50th the thickness of a human hair, but this tiny flaw proved devastating to the quality of the Hubble’s images and to the efficiency of all of its instruments.

What did the Hubble Space Telescope accomplish?

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.

Who messed up Hubble mirror?

NASA has established how a mirror aboard its $1.5 billion Hubble Telescope came to be the wrong shape. The agency said last week that errors in a test instrument apparently led Perkin-Elmer, which fabricated the optics, to finish the 2.4-metre primary mirror of the Hubble Space Telescope incorrectly.

How many Eva’s did it take to fix the Hubble?

Terms in this set (15)

How many EVA’s (spacewalk) did it take to fix Hubble? How far above Earth is Hubble? What did the first spacewalk fix on Hubble? They replaced 4 gyroscopes to repair the faulty guidance system.

Why is Hubble telescope blurry?

Ultimately the problem was traced to miscalibrated equipment during the mirror’s manufacture. The result was a mirror with an aberration one-50th the thickness of a human hair, in the grinding of the mirror.

What does WFPC2 stand for?

What space technology may one day replace the HST?

Hubble is the only telescope designed to be maintained in space by astronauts. Five Space Shuttle missions have repaired, upgraded, and replaced systems on the telescope, including all five of the main instruments.
Hubble Space Telescope.

How does Hubble camera work?

The incoming light beam from the Hubble telescope is directed into WFC3 using a pick-off mirror, and is directed to either the Ultraviolet-Visible (UVIS) channel or the Near-Infrared (NIR) channel. The light-sensing detectors in both channels are solid-state devices.
