Webb Sees Gassy Baby Stars

NASA’s James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20, 2024, image are aligned protostar outflows – jets of gas from newborn stars that all slant in the same direction. This image supports astronomers’ assumption that as clouds collapse to […]

Webb Sees Gassy Baby Stars
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.
In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.

NASA’s James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20, 2024, image are aligned protostar outflows – jets of gas from newborn stars that all slant in the same direction.

This image supports astronomers’ assumption that as clouds collapse to form stars, the stars will tend to spin in the same direction. 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.
