    In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of never-before-seen young stars that were previously shrouded in cosmic dust. The most active region appears to sparkle with massive young stars, appearing pale blue. Scattered among them are still-embedded stars, appearing red, yet to emerge from the dusty cocoon of the nebula. NIRCam is able to detect these dust-enshrouded stars thanks to its unprecedented resolution at near-infrared wavelengths.

    Ever heard of centaurs? ☄️ #shorts

    In mythology, centaurs are half-human, half-horse creatures, but in space, they’re celestial objects orbiting the Sun between Jupiter and Neptune.

    Centaurs are “hybrid” objects in the sense that they share characteristics with trans-Neptunian objects from the Kuiper Belt reservoir and short-period comets.
    A team of scientists used the James Web Telescope to study Centaur 29P.

    While data from previous observations of Centaur 29P showed a carbon monoxide (CO) gas jet pointed toward Earth, Webb parsed the jet’s composition in greater detail, and also detected multiple never-before-seen features of the centaur: two jets of carbon dioxide (CO2) emanating in the north and south directions, and another jet of CO pointing toward the north.

    Centaur 29P’s different CO and CO2 abundances suggest that the body may be composed of different pieces that coalesced together during its formation. However, other scenarios to explain Centaur 29P’s outgassing activity are still being considered.
