The beams hint at the true scale of the massive star that spawned them.

"Capturing another satellite like this in an Earth-observation image is extremely rare."

Though NGC 7456 looks like a modest spiral galaxy, new Hubble and XMM-Newton observations reveal a bustling system with star-forming regions and an active core.
