This Hubble image shows NGC 1022, a face-on barred spiral galaxy located in the constellation of Cetus, approximately 62 million light-years away. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Seth.

This infographic shows the key results from a study that has revealed the interstellar thread of phosphorus. The background of the infographic shows a part of the night sky in the constellation of Auriga, where the star-forming region AFGL 5142 is located. The ALMA image of this object is on the top left of the infographic, and one of the locations where the team found phosphorus-bearing molecules is indicated by a circle. The most common phosphorus-bearing molecule in AFGL 5142 is phosphorus monoxide, represented in orange and red in the diagram on the bottom left. Another molecule found was phosphorus nitride, represented in orange and blue. The astronomers also found phosphorus monoxide on 67P/Churyumov-Gerasimenko, shown on the bottom right.
