Hours after people around the world got a glimpse of “the deepest, sharpest infrared view of the universe” ever taken, the United States space agency has released other detailed photographs taken by the James Webb Space Telescope.

Whoops and hollers from a spritely James
Webb “cheer team” welcomed some 300
scientists, telescope engineers, politicians
and senior officials from NASA and its
international partners into a packed and
lively auditorium ahead of opening
remarks on Tuesday.
“I didn’t know I was coming to a pep rally
today,” NASA Administrator James Nelson
said from the stage, enthusing that Webb’s
“every image is a discovery.”
The “deep field” image released during a
brief White House event on Monday
evening is filled with lots of stars, with
enormous galaxies in the foreground and
faint and extremely distant galaxies
peeking through here and there.
Part of the image is light from not too long
after the Big Bang, which was 13.8 billion
years ago.
“What we saw today is the early
universe,” Harvard astronomer Dimitar
Sasselov told The Associated Press news
agency after the reveal.
Built to view its subjects chiefly in the
infrared spectrum, Webb is about 100
times more sensitive than its 30-year-old
predecessor, the Hubble Space Telescope,
which operates mainly at optical and
ultraviolet wavelengths.
The much larger light-collecting surface of
Webb’s primary mirror – an array of 18
hexagonal segments of gold-coated
beryllium metal – enables it to observe
objects at greater distances, thus further
back in time, than Hubble or any other
telescope.
One of the other images released on
Tuesday revealed a “landscape of
‘mountains’ and ‘valleys’ speckled with
glittering stars” in what’s known as the
Carina Nebula, which is located about
seven light-years away. |

wow!! so beautiful! A nebula is a distinct body of interstellar clouds. Nebulae are often star-forming regions, such as in the "Pillars of Creation" in the Eagle Nebula
