10 mesmerising star cluster images captured by NASA Hubble Space Telescope

Westerlund 2, a giant cluster of 3,000 stars, resides in a raucous stellar breeding ground known as Gum 29.

Merging Star Clusters in 30 Doradus This Hubble Space Telescope image captures two clusters full of massive stars that may be in the early stages of merging.

In 1995, the Hubble Space Telescope spent 10 straight days in a unique experiment, staring at a dark, seemingly empty patch of sky ― about the size of a pinhead held at arm's length ― near the Big Dipper.

This image of massive galaxy cluster MACS J0416.1-2403 was part of the Hubble Space Telescope's Frontier Fields project.

The scattered stars of the globular cluster NGC 6355 are strewn across this image from the Hubble Space Telescope.

This image of Caldwell 69 includes ultraviolet, visible, and infrared observations taken in 2019 and 2020 by Hubble’s Wide Field Camera 3.

Eye in the Sky This image taken with the Hubble Space Telescope features NGC 4826 — a spiral galaxy located 17 million light-years away in the constellation of Coma Berenices (Berenice’s Hair).

This image from the Hubble Space Telescope captures a small portion of the Small Magellanic Cloud (SMC).

This 100 million-year-old globular cluster is located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way and a birthplace for billions of stars.

Many colorful stars are packed close together in this Hubble Space Telescope image of the globular cluster NGC 1805.
