Although he did not specify what objects in the early universe the telescope focused on, nor how old those targets were, Nelson said the images would show the first objects ever observed. “This is something humanity has never seen before, and we are just beginning to understand what the web can and will do,” he said.


Until then, the oldest scientific data ever acquired is a series of deep imaging fields from the Space Telescope. Hubble Showing the formation of galaxies in our universe a few hundred million years later big BangWhich happened about 13.7 billion years ago.

The remarks from a NASA administrator were given at a media event at the Space Telescope Science Institute, which manages both Hubble’s operations and the new space telescope.

Another image will be the first spectrum of exoplanets taken by the instrument during Webb’s science unveiling, according to Thomas Zurbuchen, associate administrator for NASA’s Science Mission Direction, who spoke at the same event.

Such spectra, which measure the amount of light emitted at certain wavelengths, usually provide clues to a planet’s chemistry by pointing to its formation history.

“Let’s look at these worlds that keep us awake at night, while we look up at the starry sky and ask ourselves: is there life anywhere else?”, said Zurbuchen, the philosopher of the historical site.
