Hubble Captures Baby Stars and Planet Nurseries 950 Light-Years Away

A cosmic nursery where stars are being born and planets take shape is putting on a dazzling show for NASA's Hubble Space Telescope.

The new image captures a collection of young stellar objects in NGC 1333, a star-forming region about 950 light-years away in the Perseus molecular cloud. It's like catching baby photos of the universe's newest residents.

On the left side of the image, a protostar (a star still forming) glows brightly as it pulls in material from its surroundings. Two dark stripes mark its protoplanetary disk, the spinning region where planets could eventually form, along with the disk's shadow stretching across the cloud.

The center right reveals something equally remarkable: two young stars, HBC 340 and HBC 341, blasting stellar winds that carve out a fan-shaped cavity in the surrounding cloud. These winds clear away gas and dust like cosmic snowplows, creating a reflection nebula that literally fluctuates in brightness over time.

These stars belong to a class called Orion variables, named for their connection to regions like the famous Orion Nebula. They change brightness irregularly and unpredictably, possibly due to stellar flares and matter erupting from their surfaces. Eventually, they'll settle down into stable, non-variable stars.

The brightness changes in the reflection nebula happen because HBC 340, the brighter and more active of the pair, fluctuates dramatically. Researchers are watching these variations to understand how young stars behave during their wild adolescence.

Scattered throughout the image are several more beaming Orion variable stars. Four cluster near the bottom of the frame, and one shines in the top right corner. Each represents a star system in its infancy, still growing and evolving.

Why This Inspires

This image reminds us that star birth is happening all around us in the universe, even as we go about our daily lives. The same forces that created our own Sun and the planets we call home are playing out in real time, just close enough for us to witness.

Scientists captured this image to learn more about how circumstellar disks and stellar outflows work during star formation. Understanding these baby stars helps us piece together how our own solar system formed billions of years ago.

The universe is constantly creating new worlds and possibilities, 950 light-years at a time.
