A dark field has a single, colorful, blurry structure in its center. Red-colored jets extend out from the center toward the top and bottom of the frame. A dark disk covers the center. Blue outflows appear on both sides of the horizontal disk. To the lower left, a larger blue outflow extends. Więcej szczegółowych informacji w opisie poniżej.

HH 30: A Star System with Planets Now Forming

Opis: How do stars and planets form? New clues have been found in the protoplanetary system Herbig-Haro 30 by the James Webb Space Telescope in concert with Hubble and the Earth-bound ALMA. The observations show, among other things, that large dust grains are more concentrated into a central disk where they can form planets. The featured image from Webb shows many attributes of the active HH-30 system. Jets of particles are being expelled vertically, shown in red, while a dark dust-rich disk is seen across the center, blocking the light from the star or stars still forming there. Blue-reflecting dust is seen in a parabolic arc above and below the central disk, although why a tail appears on the lower left is currently unknown. Studying how planets form in HH 30 can help astronomers better understand how planets in our own Solar System once formed, including our Earth.
