can telescope see back in time ?

It is accepted that when it finally launches , the james webb telescope will be able to look even future back in time and observe events which happened long ago in galaxies far away

James webb telescope

james webb is space telescope which is go in space after the hubble telescope , it is mcuh better than hubble telescope the cost of james webb telescope is $ 9.8 billion it is a very expensiv project and in james webb telescope misson many agencies were aded lilke nasa , esa and csa.

This telescope can see back in time webb will be able to see what universe looked like around a quarter of a billion years (possible back to 100 million years ) after the big bang , when the first stars and galaxies started to from .

comparison of james webb and hubble telescope ?

Webb will primary look at the universe in the infrared ,while hubble studies it primarily at optical and ultraviolet wavelength .... Hubble is in a very close orbit around the earth , while Webb will be 1.5 million kilometers away at second Lagrange point Webb will observe primarily in the infrared and will have four science instruments to capture image and spectra of astronomical objects . these instruments will provide wavelength coverage from 0.6 to 28 micrometers the infrared part of electromagnetic spectrum goes from about 0.75 microns to a few hundred microns . the instruments in Hubble can observe a small portion of the infrared spectrum from 0.8 to 2.5 microns , but its primary capabilities are in the ultra violet and visible parts of the spectrum from 0.1 to 0.8 microns .

how many light years can the james webb telescope see ?

NASA webb telescope to see 13 billion light years away .

What come after james webb telescope ?

The wide field infrared survey telescope (WFIRST).

Why james webb telescope is so expensive ?

The JWST has a history major cost overruns and delays which have resulted in part from outside factors such as delays in deciding on a launch vehicle and adding extra funding on a launch contingencies . By 2006 , us$1 billion had been spent on developing JWST , with the budget at about us$4.5 billions at that time .

what if we don't have a brain

The brain is the most complex and important organ in the human body. The brain is made of soft nervous tissues which control all body functions. It is the center of the nervous system in all invertebrates and vertebrates. It is located in the head and functions as the coordinating center of intellectual, sensation and the nervous system. So can we live without a brain? Well, let’s see if it’s possible or not. The brain is divided into two parts: the cerebrum and the cerebellum. The cerebrum controls important functions like our learning ability, emotion, etc. while on the other hand, the cerebellum controls activities such as balance and our muscle movements, etc. But the brain also determines our personality. There are several cases that show that a brain trauma can change someone’s personality. But back to our main question which is “Can we live without a brain?” To understand this, let us look at a case. In 2014, a 24 years old Chinese woman complained in a hospital about her ...

Kardashev scale

The Kardashev scale is a method of measuring a civilization ' s level of technological advancement based on the amount of energy it is able to use. The measure was proposed by Soviet astronomer Nikolai Kardashev in 1964. The scale is hypothetical , and regards energy consumption on a cosmic scale. Various extensions of the scale have since been proposed, including a wider range of power levels (types 0, IV through VI) and the use of metrics other than pure power. Categories The Kardashev scale has three designated categories, these are: A Type I civilization , also called a planetary civilization , can use and store all of the energy available on its planet. A Type II civilization , also called a stellar civilization , can use and control energy at the scale of its planetary system. A Type III ...

Andromeda Galaxy

The Andromeda Galaxy , also known as Messier 31 , M31 , or NGC 224 and originally the Andromeda Nebula (see below), is a Barred spiral galaxy approximately 2.5 million light-years (770 Kiloparsecs ) from Earth and the nearest large galaxy to the Milky way . The galaxy's name stems from the area of Earth's sky in which it appears, the Constellation of Andromeda , which itself is named after the Ethiopian (or Phoenicia) who was the wife of Perseus in Greek mythology . The virial masses of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses (2.0 × 10 42 kilograms). The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy is more massive than the Milky Way by a margin of some 25% to 50%. This has been called...
