Telescópio Espacial Hubble captured high-definition images of the AFGL 5180 region, a star-forming zone located in the constellation Gêmeos, approximately 6,500 light-years from Terra. The observation reveals complex structures of gas and dust where new stars are being born, in a process that offers clues about the origin of Sistema Solar.
The images combine visible and infrared light data obtained by the Hubble’s WFC3 camera (Wide Field Camera 3). Este capture type allows you to penetrate the dense veil of dust that normally obstructs the observation of the interior of these regions, revealing details previously invisible to conventional telescopes.
Internal Estrutura and violent star jets
At the bright center of the AFGL 5180 region is a massive star in the process of formation, with more than eight times the mass of Sol. Essa young star accumulates large amounts of surrounding material while expelling pairs of high-speed gas jets in opposite directions — specifically toward the upper right and lower left corners of the image.
Stellar jets create cavities within the molecular cloud. Agência Espacial Europeia (ESA) compares the phenomenon to the light from a lighthouse that passes through storm clouds to illuminate the sea surface. Most of the radiation emitted by newly formed stars passes through these cavities, allowing the light to reach Terra and be detected by Hubble’s instruments.
Why infrared light is essential for observation
Regiões of star formation, known as star cradles, have extreme abundance of cosmic dust. Esse material serves as a fundamental raw material for the origin of new stars, but at the same time represents a significant obstacle to direct observation.
Visible light is easily absorbed and scattered by dust, making it impossible to view the interior of dense clouds with telescopes that capture only the visible spectrum. Infrared radiation, however, can penetrate this veil, as it has wavelengths that are less obstructed by dust particles. Essa capability allowed the Hubble to capture such a clear representation of AFGL 5180’s internal structure for the first time.
Observations include:
- Nuvens of gas and dust in red and orange coloration from infrared data
- Brilho of countless young stars in cloud gaps
- Jatos of matter ejected by the massive central star
- Cavidades created by the action of stellar jets
- Detalhes of previously hidden inner layers
Conexão with the story of Sistema Solar
Acredita The structures observed in AFGL 5180 are believed to contain valuable information about processes that occurred during the formation of Sistema Solar, approximately 4.6 billion years ago. The study of distant star-forming regions acts as a temporal window to understand how our own planetary system was born and evolved.
By observing these star cradles, astronomers trace humanity’s own cosmic roots. Cada detail revealed by Hubble offers new clues about the universal mechanisms of star creation, processes that continue to occur in galaxies near and far.
The image of AFGL 5180 was initially released by ESA/Hubble on March 8, 2021. Novas analysis of the data continues to reveal previously unknown aspects of this fascinating region of space.
