Where is the most powerful telescope on earth?
CAPE CANAVERAL, Florida (AP) — The world's largest, most powerful space telescope arrived at its observation post one million miles from Earth on Monday, a month after it lifted off on a quest to behold the dawn of the universe.
What are the 4 main telescopes in space?
Great Observatories, a semiformal grouping of four U.S. satellite observatories that had separate origins: the Hubble Space Telescope, the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
Are there microwave telescopes?
The result from the most recent space-born microwave telescope, the Wilkinson Microwave Anisotropy Probe (WMAP), has helped to accurately determine the age of the universe within 1% accuracy (13.7 billion years), and also gave an idea of what the universe looked like less than 400,000 years after the big bang.
Can I see Pluto with a telescope?
And yes, dwarf planet Pluto is visible as well for advanced observers. All you need is a cloud-free area, a modest telescope and some patience, but the upshot is astronomy is a quarantine-friendly activity.
How much does a real telescope cost?
An entry-level astrophotography telescope costs between 800 and 1,500 dollars, and between 1,500 and 3,000 dollars (or considerably more) for higher-end models. Small apochromatic telescopes are the best choice when it comes to astrophotography: they are light, compact, easy to use and provide a wide field of vision.

How many galaxies are there?
In total, Hubble has discovered about 100 billion galaxies in the Universe. However, after James Webb is fully operational, this number will probably increase to 200 billion. Moreover, scientists are not sure that even 200 billion galaxies is the final figure.
What is the cost of a telescope?
The most expensive product is Celestron 114 LCM Computerised Telescope (31150) priced at Rs. 45,788. Contrary to this, the lowest priced product is Celestron Impulse 5×30 Binocular available at Rs. 599.
How far can the biggest telescope see?
You can attach 9 more zeros to the end of this to get 1 billion light-years and another one for 10 billion light-years. 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.
Where is Hubble telescope now?
Launched on April 24, 1990, aboard the Space Shuttle Discovery, Hubble is currently located about 340 miles (547 km) above Earth's surface, where it completes 15 orbits per day — approximately one every 95 minutes.
Can a telescope blind you?
A telescope will not hurt your eyes unless you observe the Sun without proper filters. Even solar viewing, like during an eclipse, is safe if you use an appropriate and high-quality solar filter. You may find other celestial objects (like the full moon) a little uncomfortably bright, but they are not dangerous.
Does Neptune have a moon?

Can you see a galaxy with a telescope?
If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to use a telescope with an aperture of 8 inches or more. Bode's Galaxy (M81) glows brightly enough to show up through binoculars, but the larger the telescope you can point at it, the better.
How much does a NASA telescope cost?
The James Webb Space Telescope cost over $10 billion and took more than 20 years to build. NASA recently launched it to a point nearly a million miles from Earth.
How much is a professional telescope?
A professional telescope can go from $1500 all the way to $8000. You should filter the options with the amount you are comfortable spending and think hard on the intended use.
Is the space infinite?
The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
How many black holes are there?
Most stellar black holes, however, are very difficult to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone.
How far can a telescope see?
76mm/3-inch telescope: about 2.5 million light-years (such as the Andromeda Galaxy) 102mm/4-inch telescope: about 110 million light years (such as NGC 5350) 200mm/8-inch telescope: about 2 billion light years away (quasars) Hubble Space Telescope: about 13 billion light-years (the earliest stars close to the Big Bang)
Can you see the flag on the moon through a telescope?
Yes, the flag is still on the moon, but you can't see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
How far is space from Earth?
62 miles A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.
What’s the farthest satellite in space?
Voyager 1 At approximately 2:10 p.m. Pacific time on February 17, 1998, Voyager 1, launched more than two decades ago, will cruise beyond the Pioneer 10 spacecraft and become the most distant human-created object in space at 10.4 billion kilometers (6.5 billion miles.)
