James Webb s James Webb Space Telescope

Webb Space Telescope, the successor to the Hubble Space Telescope, can see deeper problems.

The James Webb Space Telescope is NASA's next orbital observation and successor to the Hubble Space Telescope. An astronomical telescope the size of a tennis court is placed far beyond the orbit of the Earth's moon, the second Lagrange point of the Earth. Webb will detect infrared radiation and will have the ability to see both at that wavelength and in the visible range that the Hubble telescope can see.

In our understanding of the universe, infrared targets are crucial. We can find farther objects, cooler objects, and see things that are invisible to the human eye through infrared light, which means that a new generation of space telescopes will be able to explore the universe farther away, ignoring the interference of dust. Weber's successful operation will open the door to a flood of new discoveries, a new beginning that expands human knowledge and consciousness and forms new parts of the universe.

Scientists and engineers put Weber together to innovate observations through advanced creative techniques. In 2018, the Webb telescope will be launched into space, and sailing into distant, isolated orbits will also begin to be pursued.

Weber will help reveal some answers to the biggest astronomical mysteries.

Dark matter is a hypothetical substance due to the existence of phenomena that cannot be explained by existing theories, it is smaller than electrons and photons, has no electric charge, does not interfere with electrons, can pass through electromagnetic waves and gravitational fields, and is an important part of the universe. Dark matter is very dense but in large quantities, so its total mass is large, and they represent 26% of the matter content in the universe, of which the human visible only accounts for less than 5% of the total matter in the universe (approx. Dark matter cannot be directly observed, but it can interfere with the light waves or gravitational pull emitted by stars, and its presence can be clearly felt.

The earliest evidence for the existence of dark matter** is the observation of the rotational velocity of dwarf ellipsoid galaxies. Modern astronomy has shown through gravitational lensing, large-scale structure formation in the universe, astronomical observations, and expanding cosmology that the density of the universe may be composed of about dark energy, baryonic matter, and dark matter.

New computer model: Dark matter is not made up of heavy particles.

Scientists published a report on Jan. 29 in a preprint of Achif that data from NASA's Chandra X-ray Observatory showed that excessive X-rays emitted at a specific energy caused a bulge on the graph. X-ray lines are known to reveal the presence of dark matter. Dark matter is an unknown substance that scientists believe the universe is made up of mostly of.

The James Webb telescope can see a distance of 20 billion light-years.

The James Webb telescope can see such a distance, which can be described as a miracle in science, 20 billion light years, that is, the distance of 20 billion years of travel at the speed of light, which is indeed an astronomical number in the astronomical number, and many people may not even dare to think about it. The author believes that the original intention of this telescope to see so far was not to observe galaxies.

Rather, I want to explore the boundaries of the universe as much as possible, and I want to verify the hypotheses that have been put forward and prove the newly proposed theories of the universe, such as the grand theory of the universe and the theory of the expansion of the universe. Because these theories deal with the limits of the universe, it is necessary to increase the number of astronomical telescopes as much as possible.

If it is just for observing starlight, it does not need to be that far away, in addition to photographing starlight, the James Webb telescope also has the following three functions:

1. James WebbSpace telescopeIn addition to photographing starlight, there is also detectionCosmic raysFeatures:The rays here are not just the kind of chaotic rays that fill the universe, the sensitive capture device carried by the James Webb telescope can capture the ancient rays radiated from the edge of the universe, and then analyze the attenuation of these rays, so as to derive the time of the universe's existence, so the James Webb space telescope has the function of detecting and analyzing cosmic rays.

2. In addition to shooting starlight, the James Webb Space Telescope also has the function of detecting magnetic fieldsThe purpose of the magnetic field detection instruments installed by scientists for telescopes is to detect new planets or stars, because only planets and stars have relatively constant magnetic fields, so that telescopes can detect more stars and asteroids.

3. In addition to shooting starlight, the James Webb telescope can also photograph black holes:Black holes cannot be photographed directly, but indirectly by the principle of diffraction, and the James Webb telescope can observe far enough that it can encounter a black hole with a high probability, so that there is a chance to photograph it.

The James Webb telescope can see tens of billions of light-years, which is a source of pride for mankind.

The James Webb Space Telescope, a telescope that can go deep into space and look back into space, was the first to capture the starry sleepy light. The overall ** distance is very long, and even scientists are ready to use it to observe the galaxies in which they were born. Bumper Jane.

The launch of NASA's James Webb Space Telescope has been postponed several times. NASA originally planned to have the spacecraft ready for launch as early as 2007, but a series of setbacks (and human error on the part of manufacturer Northrop Grumman) have delayed the project for more than a decade. The project cost about 20 times its original budget.

NASA has previously announced that the James Webb Space Telescope will tentatively be launched in 2021. And the good news is that the telescope's section has just completed a round of testing in a vacuum chamber at its manufacturing facility, which is designed to simulate the environment the telescope will experience in space.

The telescope is divided into two parts. One half is the telescope itself and the various scientific instruments of the wheel, and the other half is the spacecraft platform, allowing it to move and maintain its orbit. Half of the spacecraft has just been tested in a vacuum chamber, and it can withstand temperatures ranging from minus 235 degrees Fahrenheit to 215 degrees Fahrenheit.

Because the James Webb telescope is going to replace the Hubble telescope, it has attracted much attention.

The exploration of the depths of the universe has relied on the Hubble Telescope, which has explored a total of 2,650,000 galaxies, many of which are more than 13.3 billion years old. And people relied on the images of the Hubble telescope to draw a map of the universe, which shows the importance of the Hubble telescope. And because the Hubble telescope has been in service for more than 30 years, the energy block has been exhausted, so it needs a replacement, and the replacement for such an important thing is the James Webb telescope, which is why the James Webb telescope has attracted so much attention.

Here's a closer look at the mission of the James Webb Space Telescope:

1. The James Webb Space Telescope will continue to explore galaxies beyond the solar system:The James Webb telescope is different from near-Earth satellites in that it mainly looks beyond the solar system or even beyond the Milky Way. The James Webb telescope will continuously transmit data and images to the ground control center through photography and detection data, and then scientists will use these data to verify new physical theories and test old theories.

2. The James Webb Space Telescope will continue to explore dark matter:Because in the extraterrestrial environment of the vacuum, there are fewer interference factors, and the existence of dark matter can be detected more accurately, so as to draw a map of dark matter. If dark matter is discovered and further effectively used, it can be said that it is another leap in science and technology, because the discovery of dark matter is almost equivalent to the discovery of endless energy, so this telescope will actively explore dark matter.

3. The James Webb Space Mirror will try to share with the aliens:The space mirror will continue to emit long, slowly attenuating waves in an attempt to communicate with the aliens. Since the Hubble Telescope, the search for extraterrestrial civilizations has not stopped, and the James Webb Space Scope will continue to explore extraterrestrial civilizations.

The above is the mission of the James Webb Space Telescope, which shows that this telescope is more like a convenient way to provide theoretical research.

The telescope cost a lot of money, costing $9 billion. The telescope weighs 7 tons and has a diameter of meters. Its entry into space will usher in a new era of astronomical television.

Because this is a project that has been in the works for many years, this is the most powerful and complex space observatory in the world, to study exoplanets in new ways, to understand the structure and information of planets.

Because this telescope represents a different meaning, this telescope can help human beings study the starry sky, and many people pay attention to the development of society, so everyone also pays attention to it.
