- The Webb Space Telescope is currently the most modern and complex astronomical observatory.
- Created by NASA in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA), it will soon be sending out the first color images.
- The enthusiasm of scientists is reaching its peak, because on July 12 we will see something that humanity has never seen before.
The Webb Space Telescope was launched aboard an Ariane 5 rocket in late December 2021. A month later, he reached his final destination, point L2.
Where is the Webb telescope? L2 is the Lagrangian point, also known as Vibration pointabout 1.5 million km from Earth, where the forces of gravity and inertia are in equilibrium.
Because of this equilibrium, the body is positioned at the point L2 He does not change his position For the other two larger organisms. Vibration point is a great place to observe the universe – L2 is always in Earth’s semi-shadow where Light from the earth and the sun does not reach. Thanks to this, it is a good place to observe the region outside the solar system.
Previously, the Herschel Space Observatory and the Planck satellite were placed in orbits near L2. Web Space Telescope He will not remain at ease. It will move around point L2, but also He will travel with the earth around the sun.
The Webb Telescope is designed to study stars that formed in the early universe. It is the remnants of the alleged third group stars that still exist before the formation of galaxies. They lived for a relatively short time, about a million years, but their radiation still spreads out into space.
How does the Webb telescope work? This does not explore outer space in visible light, but make notes In the infrared. This is due to the fact that as the universe expands, visible light from distant objects moves towards the infrared and escapes, for example, Hubblewhich explores the visible part of the universe.
The infrared signals received are very weak. Objects produced after the Big Bang can be examined because the Webb telescope remains at almost very low temperatures minus 230 degrees Celsius. Hence the five-layer sunblock Each layer is the size of a tennis court. Additionally, the Webb telescope has a cooling system that keeps individual instruments cool.
One of these devices is MIRI . Tool, which is the provision of amazing swaths of space previously unknown in extraordinary images. MIRI is the most cooling and temperature sensitive mid-infrared instrument The farthest thing in the universe.
Initial plans assumed that it would cost $500 million to buildIn the end, the astronomical instrument cost 20 times more. How much did the James Webb telescope cost? Finally, the numerator stops at the expression 10 billion dollars. Why such a big difference between assumptions and actual costs?
First of all, it should be remembered that the idea of \u200b\u200bcreating this type of telescope appeared in the minds of scientists in the early 1990s. Official work on the project began in 1996and the start is optimistically planned for 2007. None of that came, and constant delays, technical failures or even a pandemic meant it finally did. web telescope Its cost is $10 billion.
Images from the Webb Telescope are a new era that opens an exciting chapter in understanding the universe. this is the reason NASA is counting the days and hours until the first images are published. What will the Webb telescope show? The list of first targets is a mystery at the moment, as is what the images from the Webb Telescope will look like. NASA However, it portends something extraordinary:
It is known that on July 12 the Webb Telescope will display color images of unprecedented sharpness. But just as important to NASA will be the spectroscopic data that astronomers can read from the light. This is to bring you closer to the answers to the father’s questions. Galactic evolutionThe life cycle of stars or the creation of the universe.
What will the Webb telescope show? The first image will be available on July 12 at 10.30 This morning, US time. Live coverage of this event will be available to watch on the NASA website And on social media.
