Left: this image from the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope shows the parent cloud LHA 120-N 180B in which the HH 1177 system was first observed. Center: this image shows the jets that accompany HH 1177; the top part of the jet is aimed slightly towards us and thus blueshifted; the bottom one is receding from us and thus redshifted. Right: this image from ALMA shows the rotating disk around the star, similarly with sides moving towards and away from us. Image credit: ESO / ALMA / NAOJ / NRAO / McLeod et al.

This composite image shows V960 Mon, a young star located over 5,000 light-years away in the constellation of Monoceros. Observations obtained using the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument on ESO’s VLT, represented in yellow in this image, show that the dusty material orbiting V960 Mon is assembling together in a series of intricate spiral arms extending to distances greater than the entire Solar System. Meanwhile, the blue regions represent data obtained with ALMA. The ALMA data peers deeper into the structure of the spiral arms, revealing large dusty clumps that could contract and collapse to form giant planets roughly the size of Jupiter via a process known as gravitational instability.

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.
