The James Webb Space Telescope (JWST) continues to provide stunning insights into the universe.
A recent image of the protostar HH30 showcases an unprecedented level of detail, thanks to JWST’s advanced infrared capabilities. First discovered by the Hubble Space Telescope (HST), HH30 is a Herbig-Haro object, a young stellar system characterized by jets of ionized gas colliding with interstellar material.
The JWST, launched on December 25, 2021, orbits the Sun at the second Lagrange point, approximately 1.5 million kilometers from Earth. With a 6.5-meter gold-coated mirror and powerful infrared instruments, it can peer through cosmic dust to study the formation of stars, galaxies, and exoplanet atmospheres.
Studying HH30 in Detail
Recently, JWST was used to observe HH30, located 450 light-years away in the constellation Taurus within the dark cloud LDN1551. At the system’s center lies a newborn star, embedded in a dense disk of gas and dust that fuels its formation. HH30’s bipolar jets, emerging at high speeds, create shock waves that heat the surrounding gas, causing it to glow in visible and infrared wavelengths.
Astronomers combined images from JWST, HST, and the Atacama Large Millimeter Array (ALMA) to examine the disk across multiple wavelengths. These observations resulted in a detailed new image, which has been named Picture of the Month.
Revealing the Structure of Planetary Formation
JWST’s infrared sensitivity enabled researchers to track sub-millimeter-sized dust grains, while ALMA provided insight into millimeter-sized grains. The findings revealed that smaller dust grains are widely distributed, whereas larger grains settle into a narrow region within the plane of the disk. This marks a key stage in planetary system formation, as dust particles begin clumping together into small rocks and eventually planets.
The study also uncovered intricate structural details within HH30. A high-velocity jet emerges from the central disk, surrounded by a broader, cone-shaped gas outflow. These observations not only enhance our understanding of exoplanetary system formation but also provide valuable insights into the origins of our own Solar System.
