It’s farther than anything mankind has looked at beforehe said during a press conference at the Space Telescope Science Institute in Baltimore, the center of operations for this $10 billion engineering gem launched in December and now at $1.5 million. kilometers from Earth.

James Webb is able to look farther into the cosmos than any telescope before it thanks to its huge main mirror and instruments that perceive infrared signals, allowing it to peer into space through clouds of dust.

It will explore solar system objects and the atmospheres of exoplanets orbiting other stars, giving us clues as to whether those atmospheres are potentially similar to our own.explained Bill Nelson.

James Webb must in particular make it possible to observe the first galaxies, formed only a few hundred million years after the big bang, and exoplanets.

A huge window

Thanks to an efficient launch by Arianespace, a NASA partner, the telescope could remain operational for 20 years, twice the lifespan originally planned, said Pam Melroy, deputy administrator of the American space agency.

On July 12, NASA intends to release the first James Webb Telescope spectroscopy of a distant planet, an exoplanet.

Spectroscopy is a tool allowing us to know the chemical and molecular composition of distant objects, and, in the case of a planet, to determine the elements of its atmosphere, to detect the presence of water or to analyze its soil.

According to Space Telescope Science Institute astronomer Nestor Espinoza, spectroscopies of exoplanets have so far been very limited compared to what the James Webb Telescope is capable of.

It’s like being in a very dark room where you only have a small pinhole to peek through., he said of the current technology. With this new telescope, you open a huge window, you can see all the little details.
