NASA's Hubble Space Telescope has captured a stunning image of the young stellar objects (YSOs) in the star-forming region NGC 1333. The breathtaking panorama reveals an assortment of newly formed stars, each with its own unique characteristics.
In the foreground, a protostar shines brightly, casting a glow on the surrounding gas and dust that forms a beautiful reflection nebula. Two dark stripes flanking the bright point are actually protoplanetary disks, where planets could form. The shadow cast across the large envelope of material around the star adds another layer of depth to this celestial scene.
Meanwhile, in the center-right, an outflow cavity reveals a fan-shaped reflection nebula, illuminated by light from nearby stars that is scattered by the surrounding gas and dust. This nebula fluctuates in brightness over time due to variations in the brightness of two Orion variable stars, HBC 340 and HBC 341.
Orion variable stars are a class of forming stars known for their irregular brightness changes, possibly caused by stellar flares and ejections of matter from their surfaces. These stars will eventually evolve into non-variable stars.
The four beaming stars near the bottom of the image and one in the top-right corner are also Orion variable stars. The rest of the cloudscape is dotted with other young stellar objects, making NGC 1333 a rich source of insights into the properties of circumstellar disks and outflows in gas and dust created by these stars.
The Perseus molecular cloud, where NGC 1333 lies about 950 light-years away, was imaged by Hubble to study young stellar objects. The images are updated daily between January 12-17, 2026, making them an excellent resource for astronomers and enthusiasts alike.
