19 Spiral Galaxies by James Webb Space Telescope

Staggering In depth Images of 19 Galaxies by NASA’s Webb Telescope

A new set of stunning images of 19 spiral galaxies has been released by the James Webb Space Telescope, showcasing the galaxies in near- and mid-infrared light.

Red dual opposing jets coming from young stars fill the darker top half of the image. At bottom center is a glowing pale yellow, cave-like structure, its top tilted toward two o’clock, with a bright star at its center. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave, 3 groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the cloud. The largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges. At top center, a star displays another, larger pinched dark shadow, this time vertically. To the left of this star is a more wispy, indistinct region.

James Webb Telescope and the images it has taken l Video

Here is the James Webb Telescope orbiting the Sun about 1 million miles from Earth and some of the iconic images it has taken in this Video.

An active star-forming region. Red dual opposing jets coming from young stars fill the darker top half of the image, while a glowing pale-yellow, cave-like structure is bottom center, tilted toward two o’clock, with a bright star at its center. The dust of the cave structure becomes wispy toward eight o’clock, trailing off and allowing stars and distant galaxies to show through. Above the arched top of the dust cave three groupings of stars with diffraction spikes are arranged. Smaller stars are scattered around the image. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the dark cloud. The image’s largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges. At the top center of the image, a star displays another, larger pinched dark shadow, this time vertically. To the left of this star is a more wispy, indistinct region, like this star is also beginning to clear out space around itself like the one at the center of the dusty cave below.

Researchers used the Atacama Cosmology Telescope to create this new map of the dark matter. The orange regions show where there is more mass; purple where there is less or none. The typical features are hundreds of millions of light years across. The whitish band shows where contaminating light from dust in our Milky Way galaxy, measured by the Planck satellite, obscures a deeper view. The new map uses light from the cosmic microwave background (CMB) essentially as a backlight to silhouette all the matter between us and the Big Bang.

This mosaic is composed of images covering the entire sky, taken by the Wide-field Infrared Survey Explorer (WISE) as part of WISE’s 2012 All-Sky Data Release. By observing the entire sky, WISE can search for faint objects, like distant galaxies, or survey groups of cosmic objects. Credits: NASA/JPL-Caltech/UCLA
