Thanks to Rubin's sensitive and detailed images using color filters that span the near-infrared to near-ultraviolet, scientists will get a clear look at which galaxies are young and actively forming stars, allowing them to trace how galaxies evolve over billions of years🌀

Why blue? These galaxies are full of hot, young stars. Like the flame of a blowtorch, blue light dominates in these because the young stars burn hotter and brighter than cooler, redder stars.🔭🧪

I've had a similar problem. So suggestions for solving it, though.

This looks great! I've just submitted it as a purchase suggestion to the Multnomah County Library system.
