Hubble celebrates its 33rd anniversary with NGC 1333

Astronomers are celebrating the NASA/ESA Hubble Space Telescope’s 33rd launch anniversary with an ethereal photo of a nearby star-forming region, NGC 1333. The nebula is in the Perseus molecular cloud, and is located approximately 960 light-years away.

Hubble’s colourful view, showcasing its unique capability to obtain images in light from ultraviolet to near-infrared, unveils an effervescent cauldron of glowing gases and pitch-black dust stirred up and blown around by several hundred newly forming stars embedded within the dark cloud. Even then, Hubble just scratches the surface; most of the star-birthing firestorm is hidden behind clouds of fine dust — essentially soot — that are thicker toward the bottom of the image. The black areas of the image are not empty space, but are filled with obscuring dust.

To capture this image, Hubble peered through a veil of dust on the edge of a giant cloud of cold molecular hydrogen — the raw material for fabricating new stars and planets under the relentless pull of gravity. The image underscores the fact that star formation is a messy process in a rambunctious Universe.

Ferocious stellar winds, likely from the bright blue star at the top of the image, are blowing through a curtain of dust. The fine dust scatters the starlight at blue wavelengths.

Farther down, another bright super-hot star shines through filaments of obscuring dust, looking like the Sun shining through scattered clouds. A diagonal string of fainter accompanying stars looks reddish because the dust is filtering their starlight, allowing more of the red light to get through.

The bottom of the picture presents a keyhole peek deep into the dark nebula. Hubble captures the reddish glow of ionised hydrogen. It looks like the finale of a fireworks display, with several overlapping events. This is caused by pencil-thin jets shooting out from newly forming stars outside the frame of view. These stars are surrounded by circumstellar discs, which may eventually produce planetary systems, and powerful magnetic fields that direct two parallel beams of hot gas deep into space, like a double lightsaber from science fiction films. They sculpt patterns on the hydrogen cocoon, like laser lightshow tracings. The jets are a star’s birth announcement.

This view offers an example of the time when our own Sun and planets formed inside such a dusty molecular cloud, 4.6 billion years ago. Our Sun didn’t form in isolation but was instead embedded inside a mosh pit of frantic stellar birth, perhaps even more energetic and massive than NGC 1333.

[Image description: A vertical image with colors ranging from blue at the top to golden in the middle and red at the bottom. At the top, a bright blue star is illuminating surrounding clouds of gas. At the center of the image, a brighter yellow star illuminates surrounding gas. The bottom of the image is noticeably darker than the rest, with the exception of a dramatic splash of red.]
