How do stars form? It’s a question that’s fascinated researchers for a long time.


Today, we know that clouds of gas give birth to stars, but the early stages of formation are still a mystery.

That’s why it helps to capture images of stars when they’re young, so researchers can better understand their chemical composition and how they develop.

Recent images by astronomers at the European Southern Observatory and Max Planck Institute in Germany capture baby stars in stunning composites of our nearby galaxies.

Here are a few gorgeous snapshots:

The photos weren’t captured in a single snap — rather, multiple telescopes on Earth and in space took shots at different wavelengths: radio, visible light, and near-infrared.

Here’s a demonstration of how researchers layered images of NGC 4303 to create a single composite.

This helps researchers capture a more complete picture of our neighboring galaxies.

Here’s a visual representation, below, of how colors across the electromagnetic spectrum are layered for each image.

Seeing the universe in richer detail will give astronomers new insight into the many mysteries we have yet to solve.
