Elon Musk & NASA Reveals The James Webb Space Telescope – Elon Musk Power


    James Webb Space Telescope

    In the beginning our universe was very hot and dense, as the universe cooled down, a few hundred million years later electrons interacting with the nucleus that made up the first atoms and finally galaxies appeared but how did they form this thing.
    We understand a $10 billion time machine that’s been in development for over 20 years, imagine you’re somewhere 65 million light years away from Earth, in Virgo. And you have a very powerful telescope, which you can use to study the Earth.

    Can dinosaurs be seen with this?

    Through the telescope you will be able to see how dinosaurs looked like on our planet, of course we will have to face many obstacles along the way, but we are talking about an incredibly powerful telescope, the James Webb Space Telescope Well, that’s 100 times more.
    Take a look at the size correlation of their primary mirror, even more powerful than the Hubble Telescope, and yet James Webb’s mirror weighs 113 kilograms 249 pounds. As much as a telescope operates in the infrared spectrum, infrared radiation can penetrate the dust cloud.
    In addition to what allows us to shape stars, Einstein’s theory of relativity states, that the space between objects in our universe expands, and so light already occurs in the form of light, stars and Galaxies travel in our direction.


    What is the Red Shift known as?

    Its waves get longer, and the light becomes infrared, also known as red shift, every time you look at the night sky, just know that there are many stars and galaxies whose Light spread and became invisible or greatly reduced.
    Here’s a question for you to see, how the James Webb Space Telescope would detect that light, assisted by a giant mirror that would increase the amount of light collected, the more light the more detailed the image mirror 18 hexagonal has been created with.
    Each segment 1.32 by 4.3 ft in diameter this size will enable the crew to bend the mirror on Earth and reveal it in space, then focus the various segments with an accuracy of one to ten thousandths of a tenth the thickness of a human hair. The mirror will be calibrated by moving it.

    Are hypersensitive infrared detectors focused?

    The light is then collected on the secondary mirror, at which point, it is reflected, and sent to the scientist. After being filtered the instrument is then focused onto hypersensitive infrared detectors, at which point the photons are converted into electrical voltages.
    The actual telescope is equipped with four tools, the NERCAM is the telescope’s primary imager in the near-infrared range, tens of sensitive detectors allow it to be detected, the first is equipped with the NERCAM chronograph in addition to the light of stars and galaxies and what they visualize. That you are blocking the sun by blocking the bright light with your hand.
    You can see the road ahead of you, a coronagraph follows a similar principle, this function will allow researchers to see more low-light galaxies and even take pictures of exoplanets, but near the cam Can’t show us everything, g we need to know about physical properties of a planet.

    Who is called Near Spece?

    It is impossible to say whether water is air, so another instrument called Near Spece would be working with the same range, by studying the spectrum of light emitted by an object we can tell its mass, temperature and chemical .
    Analyzing dim light required telescopes to look at the article for more than a hundred hours, but of course the scientists did not, working for 10 years to avoid wasting telescope resources on a single object , is equipped with a superpower to provide near-imagination spectroscopy of hundreds of objects simultaneously.
    Which was achieved by developing a new technology called the micro shutter system, the system has created 250,000 shutters that open and close In the countryside you can see at night, you can probably tell the difference because of the high amount of light in the city.


    Will the irrelevant block out the light?

    The micro shutter system will block out irrelevant light, allowing us to see the least illuminant object, which diffuses the light, the spectrum is a great deal in outer space, and allows the telescope to capture only the relevant light. Constantly have to be directed at different goals.

    Fine Guidance Sensor FGS Additionally scientists from the Canadian Space Agency have developed a near-infrared imager and stiltless spectrograph, which also takes pictures in near-infrared light, and captures spectroscopy, but not how we deal with dense dust clouds.

    Those obstructing visible near infrared light may not be able to distinguish them, and this is where the final instrument at MIRI is also equipped with a camera and a spectrograph. which has long waves that can penetrate dense dust clouds.

    Which cooling system has been developed by scientists?

    Sensitive detectors will allow us to observe the red light of newly forming stars in distant galaxies, and to issue comets with Miri, 6.7 Kelvin or negative 266.5 Celsius as it begins to capture its heat, scientists have developed an additional cooling system called a cryo cooler.

    In essence it is a sophisticated refrigerator in which helium will travel along the pipe as a result of cooling Miri, but now we have a different Sun, Moon and Earth heat problem and as a solution to this problem engineers have developed telescopes. Developed an incredible passive cooling system for the Sun Shield The size of this shield is 21 meters long and 14 meters across.

    With space in between each layer of material so that they can cool efficiently, each layer is made from a special film that can withstand very high temperatures, this material is called Kapton, in addition each layer Coated in aluminum, the first two have an additional coat of dope.

    How many kilometers from Earth must the Moon and Earth be hidden together?

    Silicon must be 1.5 million kilometers from Earth for the Sun’s shield to be able to withstand even higher temperatures to be able to simultaneously hide the Moon and Earth from the Sun, with the Hubble Space Telescope as a reference only At a distance of 547 kilometres, the James Webb Space Telescope will travel to a special location, known as Laraji.

    It is one of the five places in the solar system where the forces of gravity allow objects to remain in a fixed position relative to the earth, remember what we talked about, a folding mirror likewise sunshield and many others The components will be foldable, so scientists can fold the telescope, and pack it into the Ariane rocket.

    Which is the most reliable rocket capable of delivering telescopes into space, and now let’s talk about the most exciting thing about the James Webb Space Telescope’s ability to capture the faint infrared light emitted by the first stars in galaxies we’ve already seen. Has been mentioned.

    for example :-

    1. You can see a bumblebee’s heat signature, but why should you care about a bumblebee, did you know, that Saturn isn’t the only planet that has rings like Uranus Neptune, and Jupiter also has it just in the visible spectrum They have rings.
    2. Dark and fuzzy telescopes using the transit method in the infrared range will help us understand how well the rings around these four planets form, researchers about a detailed analysis of the atmosphere of an exoplanet in the habitable zone Are interested in located planets which means they may contain water.
    3. Using binoculars we can know the chemical composition of those planets, atmosphere scientist Machio Kaku thinks, that the chances of meeting an alien civilization are quite strong.
    4. The telescope will be able to tell us much more about the birth of stars and planets in galaxies.
    5. It could completely change science, as we know the universe holds many mysteries, but the use of the James Webb space telescope is rare.

    Hope you got the information.
    Have a nice day!!
