First-of-Its-Kind Detection Made in Striking New Webb Image ✨️

#universe #photography #space #science #stars Webb has captured a stellar phenomenon for the first time. See how those bright red, clumpy streaks in the top left are all slanted in the same direction to the same degree? They show aligned protostellar outflows, or jets of gas from newborn stars. "Astronomers have long assumed that as clouds collapse to form stars, the stars will tend to spin in the same direction,” said principal investigator Klaus Pontoppidan of NASA's Jet Propulsion Laboratory in Pasadena, California. “However, this has not been seen so directly before. These aligned, elongated structures are a historical record of the fundamental way that stars are born." Previously, the objects appeared as blobs or were invisible in optical wavelengths. Webb’s sensitive infrared vision was able to pierce through the thick dust, resolving the stars and their outflows. This area is part of the Serpens Nebula. Located 1,300 light-years from Earth, it’s only 1-2 million years old — very young in cosmic terms! It’s home to a dense cluster of newly forming stars (about 100,000 years old), seen at the center of this image. A rectangular image with black vertical rectangles at the bottle left and top right to indicate missing data. A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. The center of the image is filled with mostly blue gas. At the center, there is one particularly bright star, that has an hourglass shadow above and below it. To the right of that is what looks a vertical eye-shaped crevice with a bright star at the center. The gas to the right of the crevice is a darker orange. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.
