Overview

• Webb’s infrared image shows highly collimated, antipodal jets spanning about 8 light-years from a protostar roughly 15,000 light-years away on the Milky Way’s outskirts.
• The team estimates the central source at around 10 times the Sun’s mass and argues the jet’s scale supports a mass–jet size relationship.
• Fine filamentary structure reveals knots, bow shocks and linear chains where the outflow impacts surrounding dust and gas.
• Researchers say the nearly 180-degree, ordered geometry favors core accretion over competitive accretion for massive-star formation in this low-metallicity environment.
• The study has been accepted by The Astrophysical Journal and includes ALMA evidence of another dense core in Sh2-284 targeted for follow-up.
