Space photo of the week: James Webb telescope catches baby stars roaring to life

What it is: The Serpens Nebula

Where it is: 1,300 light-years away, in the constellation Serpens

When it was shared: Aug. 12, 2024

Why it's so special: This is a new image of an old favorite, the Serpens Nebula, where a cloud of gas and dust is lit up by starlight. Using its infrared capabilities, the James Webb Space Telescope (JWST) now reveals the source of that light: newborn stars.

The place to look in this image, taken with JWST's Near Infrared Camera, is the top-left corner. The bright-red streaks are jets of gas from newborn stars smacking into the surrounding gas and dust, creating shock waves. Crucially, they all slant in the same direction.

That's important because it provides evidence for the theory that when clouds of dust and gas collapse to form stars, all of those stars spin in the same direction. The trouble is, before JWST was around to observe in the infrared — to pierce thick clouds of dust and gas — it wasn't possible to see newborn stars or their jets in optical wavelengths, so it was impossible to confirm that theory.
