Space missions and everything that involves astronomy may seem a bit complex to many people, but it is precisely to change that that projects such as the telescope James Webb exist! The model will be launched into space on the 18th of December and should help experts to see phenomena that not even the telescope Hubble would make it. 14101q
The project, a partnership between NASA e ESA, should also help to know if there really is life outside the Planet Earth and even another Solar system. View all telescope information James Webb and how it should revolutionize how we know space.
What is the James Webb Telescope and why is it important? 5t2j5b
Developed in a partnership between NASA (North American Space Agency) and the ESA (European Space Agency), the telescope James Webb will be responsible for allowing experts to know, for example, how the first galaxies arose. This may seem simple, but by crossing the data, it becomes easier to know whether or not there is life outside Planet Earth and the Solar System where we live.
The telescope James Webb has a primary mirror that can reach 6,5 meters, being almost 3 times larger than the part in the telescope Hubble. It was even designed to be a successor to the Hubble, giving us even greater for us to know more about life in space, as well as discover the origin of various things until we get to where we are today.

Talking more about the telescope James Webb, the same is important because its technology allows our search for life outside Planet Earth to be even more intensified. That's because the mirror has 18 gold-plated hexagonal segments, each 1,32 meters in diameter. THE NASA already informed that this is the biggest mirror that it has ever built, where it will be possible to capture more light and see further.
The new model was named in honor of James Edwin Webb. This was the name of a former programmer from NASA who worked in the Apollo space program, as well as in several space missions that were essential for the knowledge of the galaxies.
What is the cost of production and maintenance made by NASA and ESA? 59o1m
You might be imagining that putting one of the best telescopes in the world into orbit can't be too cheap, right? And you're not thinking wrong. All telescope development James Webb cost US$ 10 billion (about R$ 56,2 billion) to get off the ground, in which the NASA and ESA were involved in the project.

For comparison, the telescope Hubble had a total cost (including all manufacturing and launch steps) ranging between US$ 4,5 and US$ 6 billion. In addition, it is also known that the European Union has invested more than 593 million euros in the telescope. Hubble. like the telescope James Webb is even more ambitious, the high cost so far can be justified with the possibilities of knowledge it will provide.
An important point is that the James Webb telescope will not undergo maintenance, as happens with the Hubble. The decision was taken because the new release of NASA it will be extremely far from Earth and it would be unfeasible to spend money on replacement parts and other repairs.
What changes compared to the Hubble telescope? 6x1vt
Developed to go further and also allow great astronomy scholars to see more, the telescope James Webb is not a replacement for the Hubble telescope, but a complement. Despite being larger and having greater potency, both will work together so that the discovery of possible life outside Earth is boosted.
The telescope James Webb will be 1,5 million km of our planet, at a point that bears the name of Lagrange Earth-Sun L2. To make understanding easier: the Earth is 150 million km from the sun. The Moon, which despite appearing to be close, orbits the planet where we live at approximately 345 km. the telescope Hubble, which was launched on April 24, 1990, has an altitude of 570 km above Earth.

In a comparison between the telescope's primary mirror Hubble (2,4 meters in diameter) and that of James Webb (6,5m in diameter) is that due to being almost 3 times larger than its “predecessor”, it can go further and deliver better images.
In addition, the telescope James Webb can also “see” in infrared, a technology that is not present in the Hubble. In fact, there is minimal vision in the 90's model, already with the telescope James Webb this will be done in an integral way and without loss in the image.
Why will the telescope be so far from Planet Earth? 4m6223
Due to its infrared compatibility, the James Webb it needs to be in cold regions so that there are no problems with its parts and other components. Imagine: what would all the investment be worth if, in a short time, the launch was completely destroyed? So that astronomical signals are not affected by the infrared radiation of the James Webb, everything must be very cold. THE NASA and ESA cited that, to work without problems, it is necessary that the James Webb telescope is at least -223?°C.

The other reason why the James Webb will be so far from Earth is the gravitational pull. This can be explained because the location where the telescope will be sent, which is named after Lagrangian L2, is semi-stable with respect to Floorsaws and EARTH.
In addition to preventing it from going through problems, the developers know that by placing the product at this point, it is possible to keep both our planet and the Sun and the James Webb in orbit, where the gravitational pull of the Earth and Sun “holds” the telescope. There is also low fuel consumption in this region and there is no way to refuel due to the high costs, making the Lagrange L2 a sweet spot.
How long will the James Webb Telescope be in orbit? 4l2n6j
It is expected that the telescope that will work together with the Hubble stay in space for 5 years, but this can be extended if needed. It is important to that it will take six months for the telescope to James Webb arrives at the desired location, so with the launch happening on December 18th of this year, we will only start seeing images of what is being seen from May of next year.

Both NASA as for ESA are thinking that the time in orbit will be longer, so the telescope is expected to James Webb send photos and other data that will help in the discovery of life outside the EARTH for ten years. This is the recommended date for space equipment to be in orbit. But ing that Hubble was first launched in 1990 and is still active today, despite having received some improvements. Developers want to enjoy the “new toy” to the fullest.
