Wonder of Wonders -- Behold the Universe!

"From the data I've seen so far, from the work we've seen in commissioning and then this first week of science, yeah, this is going to be revolutionary."
"These are incredible capabilities we've never had before."
Jane Rigby, Webb operations project manager, Goddard Space Flight Center, Greenbelt, Maryland.
 
"Those releases represented five days of observation with this observatory."
"And they include something that is a deeper infrared image than has ever been taken in history, deeper than Hubble images that required weeks to acquire. That was done in half a day with Webb."
Randy Kimble, Webb project scientist, Goddard. 
 
"I am so thrilled, and so relieved."
"It's just impossible to convey how hard it really was. We risked so much to say we're going to go do this, and it's so near impossible. But we did it."
John Mather, Nobel Prize winner, senior scientist, Webb project.

 Astronomers have awaited the results of the first photographs to be released, taken by the James Webb Space Telescope, the most powerful such telescope yet to search the Universe beyond our solar system, beyond our Milky Way Galaxy. The clarity of the photographs and the wide scope of far distant galaxies will in due time explain much about the Universe. Photographs are now being seen that reflect the birth and death of stars, nature's most mysterious secrets now on the verge of being unlocked through observation of what could never be imagined might be possible to analyze.
 
Graphic titled “Hot Gas Giant Exoplanet WASP-96 b Atmosphere Composition, NIRISS Single-Object Slitless Spectroscopy.” The graphic shows the transmission spectrum of the hot gas giant exoplanet WASP-96 b captured using Webb's NIRISS Single-Object Slitless Spectroscopy with an illustration of the planet and its star in the background. The data points are plotted on a graph of amount of light blocked in parts per million versus wavelength of light in microns. A curvy blue line represents a best-fit model. Four prominent peaks visible in the data and model are labeled “water, H 2 O.”

Webb captured the signature of water on giant gas planet WASP 96-b, which orbits a star 1,150 light-years away. For the first time, we've detected evidence of clouds in this exoplanet's atmosphere: nasa.gov/webbfirstimages #UnfoldTheUniverse
"[The initial deep look unveiled on July11 is] proof of concept ... whetting our appetite for the record-breaking results we now know will come from this exceptional facility."
Heidi Hammel, planetary astronomer, scheduled to use the Webb

"[The telescope, the successor to the Hubble which is still in operation] has capabilities that far surpass my most optimistic dreams."
"The capabilities of Webb are truly out of this world."
Garth Illingworth, astronomer, University of California, Santa Cruz
A world-achievement, expectations were high for the success of this new eye in the sky that would send back messages and photographs from the most distant areas of the Universe. And what was revealed in those exceptional photographs of never-imagined detail was beyond extraordinary and exciting beyond measure to the fertile, now febrile minds of the world's greatest astronomers and astrophysicists. The $10-billion investment in the James Webb Telescope sent the world of space science into orbit yesterday.
 
The first image to be revealed at the White House is that of a cluster of galaxies called SMACS 0723. which only the massive lens of the Webb could have penetrated and portrayed so stunningly. Behind the magnification of the cluster are seen faint objects of vast cosmic distance. The "highest resolution images of the infrared universe ever captured", in the words of the American president who presided over the unveiling of the images.

The European Space Agency and the Canadian Space Agency partnered with NASA, maintaining a close grasp on the first images derived from the Webb during its initial sequence of observations as it orbits the sun a million miles from Earth. A few testing-phase images of the telescope were previously released, astounding astronomers with their detailed clarity. The newly-released photographs, however, were in full colour.

This initial first scrutiny deep into the universe by the Webb has excited the appetite of the world of astronomy for what is yet to come; revolutionary views of the universe crossing cosmic distances with unrivalled resolution. The coming months will transform what is currently known and assessed as an expansion of the understanding of the most basic rules and origin of the universe will gradually be resolved.

Now the formation of the earliest galaxies will be enabled by the Webb toward more intensive study along with the evolution of the expanding universe. Even our own solar system, hosting small worlds we hardly are aware of beyond the orbit of Neptune will come under scrutiny as nature's genius is examined and understood in time and space.
