At 5,500 light-years away, Messier 4 is the closest globular cluster to Earth. Globular clusters are spherical groups of stars, held together by gravity. This image spans the wide range of wavelengths that Hubble’s instruments are sensitive to: go.nasa.gov/4uChHZ2

Welcome to Hubble's Messier Marathon: 2026 Edition! We're sharing new Hubble images of cosmic objects from the Messier catalog, compiled by French astronomer Charles Messier in the 1700s. Come back tomorrow for another new image, and catch up here ⬇️ go.nasa.gov/4sS7XYW

@NASAHubble Sounds like Messier 4 is the neighborhood's most popular hangout spot.

@NASAHubble m4 is also one of the oldest things we've found in the galaxy like 12+ billion years old basically fossil stars from when the universe was a baby

@NASAHubble I'm rather impressed how void is vast between such the congestion of celestial bodies⭐⭐⭐

@NASAHubble Sorry, I don't believe those are all stars at all, or that whatever they are are 5,500 LY away.

@NASAHubble I wonder what amazing discoveries could be made by exploring Messier 4 with the Hubble telescope.

@NASAHubble Always fascinating to hear about the UNIVERSE!

@NASAHubble So this image is when Sumer started to develop writing

@NASAHubble nuts how we think 13000 ft is high and then you see stuff like this

@NASAHubble We romanticize the stars, but even here it’s about structure and gravity, not magic. Scale reveals complexity, not simplicity, no matter how beautiful the view.

@NASAHubble 😀

@NASAHubble It’s truly amazing

@NASAHubble show us pictures of earth with people upsidedown sidewsys

@NASAHubble So real that it becomes sheer illusion.

@NASAHubble Light joins dark divides. I've heard that before...

@NASAHubble 🥰🥰🥰🥰🥰

@NASAHubble @NASAUniverse That's fascinating! Messier 4 sounds truly majestic. It's incredible to imagine a spherical group of stars held together by gravity, and even more amazing that Hubble can capture such a wide range of its wavelengths!

@NASAHubble Amazing

@NASAHubble Nebula?

@NASAHubble This is beautiful
