===Planetary formation===
An image of the protoplanetary disc surrounding [[HL Tauri]] (a very young [[T Tauri star]]<ref>{{cite journal |title=In Search of HL Tauri |journal=The Astrophysical Journal Letters |first1=David A. |last1=Weintraub |first2=Joel H. |last2=Kastner |first3=Barbara A. |last3=Whitney |volume=452 |issue=2 |pages=L141–L145 |date=October 1995 |bibcode=1995ApJ...452L.141W |doi=10.1086/309720|doi-access= }}</ref> in the constellation [[Taurus (constellation)|Taurus]]) was made public in 2014, showing a series of concentric bright rings separated by gaps, indicating protoplanet formation. {{As of|2014}}, most theories did not expect planetary formation in such a young (100,000-1,000,000-year-old) system, so the new data spurred renewed theories of protoplanetary development. One theory suggests that the faster accretion rate might be due to the complex magnetic field of the protoplanetary disc.<ref>{{cite journal |title=Spatially resolved magnetic field structure in the disc of a T Tauri star |journal=[[Nature (journal)|Nature]] |first1=Ian W. |last1=Stephens |first2=Leslie W. |last2=Looney |first3=Woojin |last3=Kwon |first4=Manuel |last4=Fernández-López |first5=A.

In 2022 ALMA initiated a program called exoALMA, a very detailed survey of 15 protoplanetary disk systems with the aim of finding still forming exoplanets.<ref>{{Cite web |title=exoALMA |url=https://www.exoalma.com/home |access-date=2025-05-15 |website=www.exoalma.com |language=en-US}}</ref><ref>{{Cite web |title=Workshops |url=https://www.exoalma.com/workshops |access-date=2025-05-15 |website=www.exoalma.com |language=en-US}}</ref>
