Summary
- NASA released a Hubble portrait of Messier 3 — an ancient globular cluster of more than 500,000 stars — rendered in red, white and blue to mark the US 250th anniversary.
- The colors track stellar temperature (hot blue to cooler red), combining ultraviolet, visible and infrared observations.
- It's part of a Hubble Treasury program surveying about half the Milky Way's known globular clusters to reconstruct how the galaxy formed; a companion image featured 13-billion-year-old NGC 6426.
The question
Long-running observatories like Hubble still deliver landmark science decades in.
