The Long Journey of the James Webb Telescope

Everything in this project is huge: at a distance of 1.5 million km from Earth (at L2 Lagrange point, the gravitational force of the Earth and the Sun causes the telescope to maintain a constant position in relation to both of these bodies. The bodies are the skies). Contains tools.

Hubble’s successor is the result of more than 20 years of technological advancement and partnerships between the Canadian space agency, NASA and the European Space Agency.

Canadian researchers have developed a scientific instrument aimed at studying distant planets and galaxies: NIRISS or Near the infrared imaging spectrophotometer.

Isabelle Bourgogne talks about the space telescope and the upcoming aircraft:

Where will our guests be before Christmas, when the telescope is launched from the Gauro site in French Guiana? Is it true that a lakh and a half kilometers cannot be fixed? What could he see that the previous space telescope could not see?

One of Hubble’s missions is to see the ends of the universe. One difference with James-heat is that the latter can be seen in infrared rays, which allow us to go back to the first ages of the universe, at the time of the formation of the first galaxies. Another feature that we did not think was possible 20 years ago, Exoplanets: James Webb can detect the atmospheres of some “small” planets and estimate their chemical composition.

What a request Tropist-1 – The red dwarf of at least seven planets – and what will be the contribution of the new telescope to this parade – 40 light years away – which attracts the attention of many astronomers.

Also, is it true that we have to be patient, because the first observations only take place six months after the time of measuring all the devices?
