Webb Snaps Highly Detailed Infrared Image of Actively Forming Stars

July 26, 2023 10:00AM (EDT)Release ID: 2023-131
At the center is a thin horizontal orange cloud known as Herbig-Haro 46/47 that is uneven with rounded ends, and tilted from bottom left to top right. It takes up about two-thirds of the length of this angle, but is thin at the opposite angle. At its center is a red-and-pink star with prominent, eight-pointed diffraction spikes. It has a central yellow-white blob. The orange lobe to the left is fatter. Just off the edge is a tiny red arc that curves in the opposite direction. The right lobe is thinner, and ends in a smaller orange semi-circle that has a faint purple outline. Just off the edge of this lobe is a slightly smaller orange sponge-like blob. A thin, undulating blue line runs from the central stars through the right lobe. A delicate, semi-transparent blue cloud known as a nebula drifts toward the top of the image and peters out toward the left of the frame, but toward the right and bottom, it ends in a soft ridge set off in a translucent orange. The background is filled with stars and galaxies.

Summary

Forecast: There’s a 100% chance of recurring two-sided jets for a pair of stars that are actively gathering mass.

Like kittens, actively forming stars are balls of energy. But instead of being overtaken by the zoomies, stars emit energy in the form of jets, creating fantastic, textured scenes. That’s the case for two tightly orbiting stars, known as Herbig-Haro 46/47.

NASA’s James Webb Space Telescope captured the most detailed portrait of these stars to date. The pair of actively forming stars has sent out jets in two directions for thousands of years. Although Herbig-Haro 46/47 has been studied by many telescopes, both on the ground and in space, since the 1950s, Webb is the first to capture them in high-resolution near-infrared light. With Webb, we can now understand more of the stars’ activity – past and present – and peer through the dusty blue nebula, which appears black in visible-light images, that surrounds them. Over time, researchers will be able to glean new details about how stars form.
