This image from NASA’s Spitzer Space Telescope shows a star formation region in molecular cloud NGC 6334, also known as the Cat's Paw Nebula. The colors correspond with emission at 3.6 microns (blue), 4.5 microns (green), and 8 microns (red). This cloud is actively forming massive stars, and is located in the constellation Scorpius, between 4,200 to 5,500 light-years from Earth. ALMA data overlaid on the image shows details of four specific areas that were observed (NGC6334I, NGC6334I(N), NGC6334IV and NGC6334V), revealing invisible forces of magnetism and gravity as they wrestle and shape the formation of stars deep within the giant molecular cloud. The color scale in the ALMA images represents the intensity of the dust emission at 1.3mm and the drapery lines represent the orientation of the magnetic field.

The bright star in the center, Fomalhaut, is surrounded by an ancient debris disk of uneven brightness. The disk is closer to the star in the south, where the disk is wider and fainter, and further from the star in the north, where the disk is narrower and brighter. The dotted ring shows the possible orbit of a planet implied by Lovell et al.

Origins of Earth’s Water. Terrestrial H2O is thought to have been delivered several billion years ago, by a combination of cometary, asteroidal and meteoritic impacts. In contrast to previous findings, new work using the ALMA telescope shows that the isotopic (D/H) ratio in Earth’s water is consistent with delivery by Halley-type comets.
