$This Webb image shows a pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center. The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars. Image credit: NASA / ESA / CSA / Joseph DePasquale, STScI.$

SPT-CL J2215-3537 resembles a blue cloud with a hazy golden light at its core. The cluster is set against the blackness of space, which is dotted with white, orange and blue specks of light. A combination of X-ray, ultraviolet, optical, and infrared light, was used to create the image. The blue cloud represents X-ray gas observed by NASA’s Chandra X-ray Observatory. The cloud is soft, and uniform in texture. Over time, galaxy clusters often merge or collide. These collisions cause disturbances and sharp features in a cluster’s gas. When a cluster takes on a smooth, calm appearance, as found here in SPT-CL J2215-3537, it indicates that no such collisions have occurred for a very long time. Astronomers call these galaxy clusters ‘relaxed.’ The hazy golden light at the heart of the cloud represents a massive central galaxy with a large amount of star formation. This central galaxy is quite isolated within the blue gas cloud. There are relatively few nearby specks of light near the central galaxy, and none are as bright or as large. No other large galaxies have been found within 600,000 light-years of the central galaxy. This implies that SPT-CL J2215-3537 has not experienced a galaxy merger in the last billion years.

This ALMA image shows the young planetary system PDS 70. The system features a star at its center, around which the planet PDS 70b (highlighted with a solid yellow circle) is orbiting. On the same orbit as PDS 70b, indicated by a solid yellow ellipse, Balsalobre-Ruza et al. detected a cloud of debris (circled by a yellow dotted line) that could be the building blocks of a new planet or the remnants of one already formed. The ring-like structure that dominates the image is a circumstellar disk of material, out of which planets are forming. There is in fact another planet in this system: PDS 70c, seen at 3 o’clock right next to the inner rim of the disk. Image credit: ALMA / ESO / NAOJ / NRAO / Balsalobre-Ruza et al.

This Hubble image shows Arp 263, an irregular galaxy located 27.1 million light-years away in the constellation of Leo. The color image of Arp 263 was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys and Wide Field Camera 3. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
