Serpens (NIRCam Image) In this image of the Serpens Nebula from the Near-Infrared Camera (NIRCam) on NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). In the Webb image, these jets are signified by bright clumpy streaks that appear red, which are shockwaves from the jet hitting surrounding gas and dust. The Serpens Nebula, located 1,300 light-years from Earth, is home to a particularly dense cluster of newly forming stars (~100,000 years old), some of which will eventually grow to the mass of our Sun. This region has been home to other coincidental discoveries, including the flapping “Bat Shadow,” which earned its name when 2020 data from NASA’s Hubble Space Telescope revealed a shadow from a star’s planet-forming disc to flap, or shift. This feature is visible at the centre of the Webb image. To the right of the “Bat Shadow” lies another intriguing feature—an eye-shaped crevice, which appears as if a star is bursting through. However, astronomers say looks may be deceiving here. This could just be gases of different densities layered on top of one another, similar to what is seen in the famous Pillars of Creation. And to the right of that, an extremely dark patch could be a similar occurrence. This gas and dust are so dense in comparison to the rest of the region, no near-infrared light is getting through.
