Why does the Hubble Space Telescope take images that are so much clearer than earthbound telescopes?
Hubble views the universe with greater precision than Earth-based telescopes because it is not hampered by Earth’s atmosphere. The atmosphere distorts light that travels through it and blurs images taken of outer space.
How long does it take for the Hubble telescope to take a photo?
One of the most detailed image is the Ultra-Deep Field that required 11.3 days with 112 exposures for the 435 and 606 nm and 288 exposures for the 775 and 850 nm. For a total exposure time of around 1 million of seconds.
Can the Hubble telescope see back in time?
Hubble is limited in how far back in time it can look, so finding this galaxy was kind of a lucky break. Astronomers only spotted it because decades of using Hubble have let them scour much of the sky, and this particular early galaxy is surprisingly bright.
Can the Hubble telescope see Pluto?
“It’s fantastic. Hubble has brought Pluto from a fuzzy, distant dot of light, to a world which we can begin to map, and watch for surface changes. Hubble’s view of tiny, distant Pluto is reminiscent of looking at Mars through a small telescope,” said Stern.
What makes the Hubble telescope so powerful?
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 telescope the most powerful telescope?
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.
