This ALMA image shows the planet-forming disk around the young star RU Lupi. The inset image (lower left, red disk) shows the DSHARP observation of the dust disk with rings and gaps that hint at the presence of forming planets. The new observation shows a large spiral structure (blue), made out of gas, that spans far beyond the compact dust disk. Image credit: ALMA / ESO / NAOJ / NRAO / J. Huang and S.

An artist’s impression of the atmosphere of Antares. As seen with the naked eye (up until the photosphere), Antares is around 700 times larger than our sun, big enough to fill the Solar System beyond the orbit of Mars (Solar System scale shown for comparison). But ALMA and VLA showed that its atmosphere, including the lower and upper chromosphere and wind zones, reaches out 12 times farther than that. Image credit: NRAO / AUI / NSF / S. Dagnello.

This ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary system HD 101584. The colors represent speed, going from blue (gas moving the fastest towards us) to red (gas moving the fastest away from us). Jets, almost along the line of sight, propel the material in blue and red. The stars in the binary are located at the single bright dot at the center of the ring-like structure shown in green, which is moving with the same velocity as the system as a whole along the line of sight. Astronomers believe this ring has its origin in the material ejected as the lower mass star in the binary spiraled towards its red-giant partner.

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.
