Summary
[edit]
| Description |
Countdown to a new star ⏳ Hidden in the neck of this “hourglass” of light are the very beginnings of a new star — a protostar. The clouds of dust and gas within this region are only visible in infrared light, the wavelengths that Webb specializes in. This protostar is a hot, puffy clump of gas that’s only a fraction of the mass of our Sun. As it draws material in, its core will compress, get hotter, and eventually begin nuclear fusion — creating a star! See that dark line at the very center of the “hourglass”? That’s an edge-on view of a protoplanetary disk, or the disk of material being pulled into the star as it forms. It’s about the size of our solar system and may eventually clump into planets, giving us a window into our solar system’s history. Light from the protostar is illuminating cavities in the dust and gas above and below its disk. (Think of flashlights pointing in opposite directions, each shining a cone of light.) The blue areas are where dust is thinnest, while orange represents thicker layers of dust. Read more: www.nasa.gov/feature/goddard/2022/nasa-s-webb-catches-fie...

This cloud of dust and gas is illuminated by light from a protostar, a star in the earliest stages of formation. The upper “bulb” of the hourglass is orange, while the lower “bulb” transitions from white to dark blue. Together, the two bulbs stretch out like butterfly wings turned 90 degrees to the side. Extending from the upper and lower bulbs are long, wispy filaments of color, looking almost like burning fire. In the center of the hourglass shape is a small, dark demarcation line. This line is an edge-on view of a protoplanetary disk, a disk of material being pulled into a star as it forms.] |
