What has the Hubble Space Telescope taught us about space?
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. And Hubble has helped scientists learn more about explosions that happen when huge stars burn out.
What are some at least 2 advantages of having the Hubble space telescope in space?
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 does the Hubble telescope produce higher quality pictures of space?
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 did we do about the Hubble Space Telescope flaw?
The result was a mirror with an aberration one-50th the thickness of a human hair, in the grinding of the mirror. Replacing the mirror was not practical, so the best solution was to build replacement instruments that fixed the flaw much the same way a pair of glasses correct the vision of a near-sighted person.
Why is the Hubble telescope named Hubble?
The NASA Hubble Space Telescope was named after astronomer Edwin Hubble who studied distant galaxies.
Why Hubble telescope is much effective than telescopes on the ground?
Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. They’re also able to detect frequencies and wavelengths across the entire electromagnetic spectrum. Other space telescopes cannot be serviced this way.
How is the Hubble telescope aimed?
The Magnetic Sensing System acts as Hubble’s compass, measuring the telescope’s orientation in relation to Earth’s magnetic field. When Hubble rotates, its gyroscopes measure the direction the telescope is turning and the rate of that rotation. Hubble has some of the most accurate and stable gyroscopes ever built.
What are 5 discoveries of the Hubble Space Telescope?
Top 5 discoveries from the Hubble Space Telescope
- The Hubble Space Telescope, moments after release from the shuttle Discovery on April 25, 1990, one day after its launch from Earth.
- Big Science rock star.
- How old is the universe?
- The rate of a universe expanding.
- Stars and galaxies like grains of sand.
Was the Hubble telescope fixed?
NASA finally fixed the Hubble Space Telescope after nearly five weeks without science operations. Hubble switched to backup hardware to correct the mysterious glitch that took it offline. Hubble’s age likely caused the problem.
How big is the Hubble Space Telescope?
Hubble Space Telescope is about the size of a large school bus. It weighs 24,500 pounds. That’s just under two adult male African bush elephants. Hubble gathers energy from the sun using two 25-foot solar panels.
What is the domain of the Hubble telescope?
Hubble, HST. The Hubble Space Telescope was designed to provide clear and deep views of distant galaxies and stars and most of the planets in our solar system. Hubble’s domain extends from the ultraviolet, through the visible, and to the near-infrared.
How did NASA celebrate the 20th anniversary of the Hubble 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.
What are the instruments used in the Hubble Space Telescope?
Initial instruments on Hubble included the Wide Field Planetary Camera, the Goddard High Resolution Spectrograph (GHRS), the Faint Object Camera (FOC), the Faint Object Spectrograph (FOS) and the High Speed Photometer. Hubble experienced equipment issues right off the bat.
