Herbig-Haro 46/47 Text Description
Extended Description
At the center is a thin horizontal orange cloud known as Herbig-Haro 46/47 that is uneven with rounded ends, and oriented diagonally at 45 degrees from the horizontal. It takes up about two-thirds of the length from the bottom left to the top right. At its center is a set of very large red-and-pink diffraction spikes in Webb’s eight-pointed pattern. The vertical spikes extend almost to the top and bottom of the frame. The smaller, fainter diffraction spikes in the center are aligned horizontally, but one set of the longer, more opaque spikes run along the orange cloud. At the middle of the diffraction spikes is a yellow-white blob, which hides two tightly orbiting stars.
The orange lobe to the left is fatter, ending in a rounder edge. Overall, this lobe is more continuous, though there’s an apparent absence of matter toward the bottom center. Just off the edge of this lobe is a tiny red arc that curves in the opposite direction and is fully separated from the lobe.
The right lobe is thinner overall, and ends in a smaller orange semi-circle that has a faint purple outline. Just off the edge of this lobe, also fully separated, is a slightly smaller orange sponge-like blob. A thin, undulating blue line runs from the central stars toward the upper right, through the right lobe, and a fainter one is partially covered by the red diffraction spike.
A delicate, semi-transparent blue cloud known as a nebula covers the majority of the orange lobes, but ends in a light orange line about halfway between the central stars and the end of the right lobe. It extends toward the top and fades to the left, not extending beyond the left lobe. Along the right and bottom edge, the nebula appears in a soft orange outline, like a backward L.
To the bottom right of the central red stars with prominent diffraction spikes are two large background stars that have large blue diffraction spikes. Other larger blue stars dot the scene, but their diffraction spikes are less than half or a quarter of the size. All across the image, the background is filled with tiny stars with miniature diffractions spikes, circular and spiral galaxies in whites and pinks, and tiny red dots which are distant galaxies.
There are 11 points of interest marked on the image. Each is labeled with one of three icons: a plus symbol, a picture icon, and a video play icon.
