In this Hubble image, the disk of the jellyfish galaxy JO206 is trailed by long tendrils of bright star formation that stretch towards the bottom right of the image, just as jellyfish trail tentacles behind them. The color image was made from separate exposures taken in the visible, ultraviolet and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). The image is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Ongoing star formation processes as observed by VIRCAM/VISTA in the VISIONS program. The top panel shows L1688 in the Ophiuchus star-forming complex, depicting several dozen prominent young stellar objects located within one of the closest embedded clusters to Earth. The young stars are surrounded by a highly structured cloud composed of gas and dust that is largely being shaped by young, optically revealed hot stars in the vicinity. The bottom panels further highlight the complex morphology of the gaseous, dusty neighborhood of partly concealed young stars in the Ophiuchus molecular clouds L1709 and L1689.

The left panel shows a three-color composite mosaic of NGC 346 combining Webb’s F277W (blue), F335M (green) and F444W (red) filters. The region is rich in structures of knots, arcs and filaments. Areas of bright pink and/or red emission are associated with clumpy star formation. The spatially resolved PAH emission excited by ultraviolet photons in green is brightest in regions corresponding to the edges of dense material, characteristic of a photodissociation region. Massive stars, stars belonging to the BS90 cluster (circled in green) and the Small Magellanic Cloud field population are also visible. The right panel shows a mosaic image from the F335M filter showing four different populations of stars: pre-main-sequence stars (blue circles), young stellar objects with Paα (orange diamonds), young stellar objects without Paα (red squares) and stars matched with the HST-PMS catalogue (purple stars).

This image, taken by the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope, shows the star cluster NGC 346. Webb reveals the presence of many more building blocks than previously expected, not only for stars, but also planets, in the form of clouds packed with dust and hydrogen. The plumes and arcs of gas in this image contains two types of hydrogen. The pink gas represents energized hydrogen, which is typically as hot as around 10,000 degrees Celsius (approximately 18,000 degrees Fahrenheit) or more, while the more orange gas represents dense, molecular hydrogen, which is much colder at around minus 200 degrees Celsius or less (approximately minus 300 degrees Fahrenheit), and associated dust. The colder gas provides an excellent environment for stars to form, and, as they do, they change the environment around them. The effect of this is seen in the various ridges throughout, which are created as the light of these young stars breaks down the dense clouds. The many pillars of glowing gas show the effects of this stellar erosion throughout the region. In this image blue was assigned to the wavelength of 2.0 microns (F200W), green was assigned to 2.77 microns (F277W), orange was assigned to 3.35 microns (F335M), and red was assigned to 4.44 microns (F444W).
