Hubble Eyes a Brilliant Star Cluster

A field of blue-white, reddish-gold, and white stars fills the view
ESA/Hubble & NASA, R. Cohen

This image taken with the NASA/ESA Hubble Space Telescope shows Terzan 1, a globular cluster that lies about 22,000 light-years from Earth in the constellation Scorpius. It is one of 11 globular clusters that were discovered by the Turkish-Armenian astronomer Agop Terzan between 1966 and 1971 when he was working in France, based mostly at Lyon Observatory.

Terzan 1 is not a new target for Hubble. An image of the cluster was released back in 2015, taken by Hubble’s Wide Field and Planetary Camera 2 (WFPC2). That instrument was replaced by the Wide Field Camera 3 (WFC3) during the 2009 Hubble servicing mission. WFC3 has both superior resolving power and a wider field of view than WFPC2, and the improvement is obvious in this fantastically detailed image.

A bright, white galactic core shines near the center of the image with a faint bar of stars extending from it, diagonally to the right. Faint, hazy spiral arms encircle the core, with several distant stars and bright blue foreground stars with diffraction spikes scattered throughout the image, all against black space.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
