Webb Telescope: What will scientists learn?
Wednesday, 13 July 2022 06:49
The James Webb Space Telescope's first images aren't just breathtaking—they contain a wealth of scientific insights and clues that researchers are eager to pursue.
Here are some of the things scientists now hope to learn.
Into the deep
Webb's first image, released Monday, delivered the deepest and sharpest infrared image of the distant universe so far, "Webb's First Deep Field."
The white circles and ellipses are from the galaxy cluster in the foreground called SMACS 0723, as it appeared more than 4.6 billion years ago—roughly when our Sun formed too.
The reddish arcs are from light from ancient galaxies that has traveled more than 13 billion years, bending around the foreground cluster, which acts as a gravitational lens.
First JWST images excite and relieve astronomers

NASA released the long-anticipated first science observations from the James Webb Space Telescope July 12, the culmination of decades of work and the start of a new era in astrophysics.

Baby stars, dancing galaxies: NASA shows new cosmic views
Tuesday, 12 July 2022 20:30
A sparkling landscape of baby stars. A foamy blue and orange view of a dying star. Five galaxies in a cosmic dance. The splendors of the universe glowed in a new batch of images released Tuesday from NASA's powerful new telescope.
The unveiling from the $10 billion James Webb Space Telescope began Monday at the White House with a sneak peek of the first shot—a jumble of distant galaxies that went deeper into the cosmos than humanity has ever seen.
Webb delivers deepest infrared image of Universe yet in special briefing
Tuesday, 12 July 2022 20:30
The international NASA/ESA/CSA James Webb Space Telescope has delivered the deepest, sharpest infrared image of the distant Universe so far.
U.S. President Joe Biden unveiled the image of galaxy cluster SMACS 0723, known as Webb’s First Deep Field, during a White House event on Monday 11 July.
OneWeb backs up Starlink 5G interference warning

Plans to use the 12 GHz band for terrestrial 5G would severely disrupt non-geostationary orbit (NGSO) broadband across the United States, OneWeb said July 11 in analysis supporting an earlier study from SpaceX.

Webb reveals cosmic cliffs, glittering landscape of star birth
Tuesday, 12 July 2022 14:34
This landscape of "mountains" and "valleys" speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA's new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.
Called the Cosmic Cliffs, Webb's seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest "peaks" in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.
The blistering, ultraviolet radiation from the young stars is sculpting the nebula's wall by slowly eroding it away. Dramatic pillars tower above the glowing wall of gas, resisting this radiation. The "steam" that appears to rise from the celestial "mountains" is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation.
Webb captures dying star's final 'performance' in fine detail
Tuesday, 12 July 2022 14:30
Some stars save the best for last.
The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA's James Webb Space Telescope has revealed for the first time that this star is cloaked in dust.
Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away.
Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one—clouds of gas and dust expelled by dying stars. Understanding which molecules are present, and where they lie throughout the shells of gas and dust will help researchers refine their knowledge of these objects.
This observation shows the Southern Ring Nebula almost face-on, but if we could rotate it to view it edge-on, its three-dimensional shape would more clearly look like two bowls placed together at the bottom, opening away from one another with a large hole at the center.
Webb reveals “Cosmic Cliffs” – a glittering landscape of star birth
Tuesday, 12 July 2022 14:22
The NASA/ESA/CSA James Webb Space Telescope reveals emerging stellar nurseries and individual stars in Carina Nebula that were previously obscured.
The new images showcase how Webb’s cameras can peer through cosmic dust, shedding new light on how stars form. Objects in earliest, rapid phases of star formation difficult to capture, but Webb’s extreme sensitivity, spatial resolution, and imaging capability can chronicle these elusive events.
