How To Calculate The Time For Telescope Need To Monitor Galaxy 13 Billion Light Years Away? (Solution found)

Where can I get information on how to compute the estimated limiting magnitude of a telescope?

  • Calculate the estimated limiting magnitude of a telescope’s aperture. Calculation formula: 7.7 + (5 X Log (Telescope Aperture in centimeters)) Calculate the light grip ratio of two telescopes in comparison to one another.

How can telescopes see billions of light years away?

An individual star 9 billion light-years away may be seen by astronomers thanks to the use of a gravitational lens. Scientists frequently employ a technique known as Gravitational Lensing when trying to understand the most distant objects in the Universe. Individual stars in faraway galaxies may now be studied using this technology, which was previously impossible.

How can we see farther than 13.8 billion light years?

Even if the fabric of space has remained same throughout time, there are a plethora of things we may observe now that could be more than 13.8 billion light-years away in distance. If a faraway object emits light and then moves swiftly away from us, it may be as far away as double the distance traveled by light at the present time.

Can we see a galaxy that is 12 billion light years away?

Even if the fabric of space has remained same over time, there are several things that we can observe now that might be more than 13.8 billion light-years away from us. If a faraway object emits light and then moves fast away from us, it might be as far away as double the distance traveled by light at the time of our observation.

How far can a 70mm telescope see?

It is quite easy to observe every planet in the Solar System using a telescope of 70mm aperture. On the Moon, you will be able to get a close look at the surface and easily discern the majority of its distinguishable features and craters. Mars is going to look fantastic.

Why is universe 13.7 billion years old?

It was around 13.7 billion years ago that our universe was formed as a result of a huge expansion that puffed space up like a big balloon. To put it another way, the Big Bang hypothesis is widely accepted among cosmologists and theoretical physicists, and it is supported by practically all of them. This view is supported by a substantial and strong body of evidence.

How do they know the universe is 13.7 billion years old?

We do not know the precise age of the universe, but we believe it to be somewhere in the neighborhood of 13 billion years – give or take a few billion years here and there. In order to figure out how old we are, astronomers use two different methods: (a) hunting for the oldest stars, and (b) calculating the rate of expansion of the universe and projecting the results back to when the cosmos first began.

How do you calculate light-years?

A light-year is the distance traveled by light in a single year. What is the distance between you and me? One light-year may be calculated by multiplying the number of seconds in a year by the amount of miles or kilometers that light travels in a second, and the result is one light-year.

How old is water in the universe?

The zircon mineralogy has revealed that liquid water and an atmosphere must have existed 4.404 0.008 billion years ago, which is quite close to the time of Earth’s origin.

How many ly away is Andromeda?

The Andromeda galaxy, which is the nearest big galaxy to us, is 2.5 million light-years away. As a result, we get to view Andromeda as it was 2.5 million years ago today. There are billions of galaxies in the cosmos, all of which are far further away than this one. Some of these galaxies are thousands of light years distant.

How can the universe be 46 billion light-years?

You may believe that in a Universe where the speed of light is limited, that would be 13.8 billion light years: the age of the Universe multiplied by the speed of light. However, that is not the case in reality. In reality, humans can see for a total of 92 billion light years in all directions, which is a total of 46 billion light years in all directions.

How far away is Hubble telescope?

Because of Hubble’s low-Earth orbit, astronauts were able to visit the telescope on several occasions over the years to repair and update its components. Hubble is now situated 340 miles (547 kilometers) above the surface of the Earth.
