You can be forgiven for not caring about the science behind this image. It's like a piece of natural art you can't take your eyes off.

B-Type stars are the second most massive type of star, and one of them sits within this image. We can tell it’s there because it’s launching a massive jet in our direction, lighting up the region and generating this captivating image. The B-Type protostar’s jets are collimated, meaning that they’re parallel. As a result, they don’t spread out much and extend a great distance in straight lines.
These protostellar jets play a role in star formation, but the details aren’t clear. The type of star behind it all is sometimes called a ZAMS star, for zero-age main sequence. It’ll eventually be on the main sequence, but for now the young star is still forming and acquiring mass, yet its blasting some of it back out into space.
Researchers have made progress since then, and the picture has become clearer. While outflows from smaller stars are typically driven by magnetic forces, outflows from luminous B-Type stars are driven energetically. However, the magnetic fields still influences how the matter flows and determines much of what we can see.
