Astronomers Capture Images: The Formation of a Newly Born Star
The James Webb Space Telescope (JWST) continues to provide unique images of the universe. Most recently, a fascinating image of the HH30 protostar was obtained. This object, initially discovered by the Hubble Space Telescope, was examined with unprecedented details thanks to the advanced technology of the JWST.
As the James Webb Space Telescope (JWST) continues its exploration of the universe, it has unveiled the mesmerizing details of the HH30 protostar located in the Taurus constellation.
Initially spotted by the Hubble Space Telescope, this young star was examined in a way never seen before, thanks to the powerful infrared detectors of JWST.
This discovery revealing the shaping process of a newborn star provides significant clues about planet formation.
LOCATION AND CHARACTERISTICS
Located in the Taurus constellation about 450 light-years away from Earth, HH30 is a system hidden within the dark molecular cloud LDN1551. This system hosts a newly born star surrounded by a dense gas and dust disk. HH30 is classified as a Herbig-Haro object, a bright nebula formed by the collision of fast ionized gas jets emitted from new stars with surrounding matter.
DETAILED EXAMINATIONS
The strong infrared detectors of the JWST allowed for a detailed examination of HH30’s structure. The obtained images revealed a cone-shaped outflow made of gas and dust ejected from the protostar, as well as a very narrow jet flow. JWST’s precise equipment enabled the tracking of the movements of dust particles within the protostar.
DUST PARTICLES AND PLANET FORMATION
The dynamics of the gas and dust outflows in HH30’s structure became clearer through observations supported by the ALMA telescope. Studies showed that larger dust particles moving within the disk created a thin layer. This process is considered a critical stage of planet formation, as dust particles come together to form larger rocks and eventually planets.
JET FLOW AND SCIENTIFIC EVIDENCE
The presence of a narrow and fast jet originating from the center of HH30 was revealed through examinations. Around this jet, a wider, cone-shaped gas flow exists. These observations not only shed light on the formation of HH30 but also provide important insights into the birth of our solar system and other planetary systems.
