In my opinion, it's the Webb's most beautiful image so far. What do you think? 🤩🤔
Astronomers focused three of Webb’s high-resolution infrared instruments on the Tarantula. Viewed with Webb’s Near-Infrared Camera (NIRCam), the region resembles a burrowing tarantula’s home, lined with its silk. The nebula’s cavity centered in the NIRCam image has been hollowed out by blistering radiation from a cluster of massive young stars, which sparkle pale blue in the image. Only the densest surrounding areas of the nebula resist erosion by these stars’ powerful stellar winds, forming pillars that appear to point back toward the cluster. These pillars contain forming protostars, which will eventually emerge from their dusty cocoons and take their turn shaping the nebula.

Is that a butterfly?🦋
👉Butterfly nebula is a bipolar planetary nebula located about 4,000 lightyears away in the Scorpion (Scorpius) constellation. It's wingspan covers over 3 light-years.
👉The nebula has a very complex structer. It's central star is one of the hottest known stars with a surface temperature in excess of 250,000 degrees Celsius. It means that the originating star must have been massive.
🌟The central star is encapsuled by a dense equatorial disc of gas and dust. Thus the shining bright nebula is hidden from direct view. The disc may have caused the star to ouflow and form the wings or the hourglass shape. In the featured image, light emitted by iron is highlighted in red.
🤨Good to know: Planetary nebulas evolve from outer atmospheres of stars like the Sun, but usually fade in about 20,000 years.
