And you thought your day was busy? we-are-star-stuff: A map of our galaxy the Milky Way, showing pulsars (red), planetary nebulae (blue), globular clusters (yellow), and the orbits of several stars. And yet our galaxy is a tiny place.
The crammed centre of Messier 22 This image shows the centre of the globular cluster Messier also known as as observed by the NASA/ESA Hubble Space Telescope. Messier 22 is one of about 150 globular clusters in the Milky Way and at just
This image captures the stunning NGC a globular cluster light-years away in the constellation of Serpens (The Serpent) that measures one light-year across. Globular clusters are tightly bound groups of stars which orbit galaxies.
Hubble Space Telescope photo taken March 16 of Messier 9 shows globular cluster of thousands of colorful stars — the blue stars are hotter while red stars are cooler. Messier 9 contains some of the oldest stars in the galaxy.
infinity-imagined: Super Star Cluster Westerlund This cluster is so massive that it is expected to eventually evolve into a globular cluster. It hosts a dozen O-class hypergiant stars, each one with a luminosity - times greater than that of our Sun.
Star cluster Messier 10 lies about 15 000 light-years from Earth, in the constellation of Ophiuchus (The Serpent Bearer). At around 80 light-years across, it should appear about two-thirds the size of the moon.
