NASA Administrator Bill Nelson said Wednesday the agency will release the "deepest image of our Universe that has ever been taken"
"If you think about that, this is farther than humanity has ever looked before," Nelson declared in a press conference in the Space Telescope Science Institute
Webb is able to look further into the universe than any telescope because of its huge primary mirror as well as its instruments that focus on the infrared which allows it to look through gas, dust.
"It's going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own," - Nelson
"It may answer some questions that we have: Where do we come from? What more is out there? Who are we? Also, it's going to answer some questions that we don't even know what the questions are."
Since Universe expanded, light of early stars shifted from visible and ultraviolet wavelength that they were emitting, to infrared wavelength that are longer which Webb can detect with high resolution
The good news is that NASA vice-administrator Pam Melroy revealed that, because of the efficient launch conducted by NASA's partner Arianespace the telescope can remain operational for 20 years.
NASA plans to also release Webb's first-ever spectroscopy of the distant planet known as an exoplanet on the 12th of July. NASA's chief researcher Thomas Zurbuchen.
The planetary spectrum helps determine its atmosphere as well as other aspects like whether or not it is surrounded by water and what its ground is similar to.
"Right from the beginning, we'll look at these worlds out there that keep us awake at night we look into the sky and wonder as we're looking out there, is there life elsewhere?" said Zurbuchen.
"It's like being in a room that is very dark and you only have a little pinhole you can look through," With Webb, "You've opened a huge window, you can see all the little details."
