This was published early in October, but it is quite remarkable: DG Taurus has a very smooth proto-planetary disk, without any grooves, which means it is in an state prior to planet formation…

However, polarized observations showed some structure in the outer regions, which might be the beginning of planet formation!

Multiple panels with Observations on top, and Simulations on the bottom. On the top, there are two rows: the first row shows images in 0.87, 1.3, and 3.1 mm, and the bottom row shows the polarization at 0.87 and 3.1 mm (no polarization image is shown for 1.3 mm). On the bottom, there are also two rows: the first row shows simulated images for both 0.87, 1.3, and 3.1 mm, and the bottom row shows the simulated polarization at 0.87 and 3.1 mm. There is much agreement between the images, but the polarization seems different, specially for 3.1 mm.

The power of multiwavelength astronomy in action: A research group led by Philipp Weber of the Universidad de Santiago de Chile (USACH) and Millennium Nucleus on Young Exoplanets and their Moons (YEMS) used ALMA to check on a young star, V960 Mon. Beyond the dust detectable with SPHERE, ALMA showed spiral arms of gas that are fragmenting, and have masses that can be progenitors of future giant planets.

This result is remarkable: ALMA has found in the PDS 70 system a cloud of debris which is in trojan formation with a potential exoplanet, which might be another forming planet in a Lagrange point with respect to the previously detected exoplanet. This work is trying to collect evidence for more exotrojan bodies.
