Astronomers capture the birth of planets around a baby sun outside our solar system

ORION NEBULA CONSTELLATION, JUL 17 – Observations reveal hot minerals condensing in HOPS-315's protoplanetary disk, marking the first direct evidence of planet formation around a sun-like star, researchers say.

  • An international team of astronomers identified the earliest moment of planet formation around the baby star HOPS-315, publishing their results on July 16 in Nature.
  • They accomplished this by examining infrared observations collected by the James Webb telescope alongside radio data obtained via the ALMA array, which uncovered the initial condensation of hot minerals within the star’s protoplanetary disc.
  • Located about 1,300 light-years away, HOPS-315 shows strong similarities to the early Solar System and offers a unique way to study planetary formation processes previously unseen outside our Sun.
  • Lead researcher Melissa McClure stated that their study marks the first occasion where the initial phase of planet formation has been observed around a star besides the Sun, while Edwin Bergin emphasized that this phenomenon has not previously been detected in any protoplanetary disk beyond our own solar system.
  • This discovery offers new insights into the origins of planetary systems and demonstrates how combined JWST and ALMA observations can effectively explore the earliest planet-forming stages.
