This Hubble image shows the globular cluster NGC 2005. The color composite was assembled from images taken in visible and near-infrared light by Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This image shows a region near the center of our Milky Way Galaxy in X-ray and radio light. At the bottom of the image, near the center, is a brilliant, tangled knot of material that resembles a paint splatter. This is the brightest region in the image, and it contains the supermassive black hole at the center of our Galaxy, known as Sagittarius A*. The lower third of the image resembles an angry firestorm. Streaks of red and orange are scattered in every direction, as if a legion of embers from a fire crackled and popped into the air all at once. Flame-like structures lick toward the center from our right. Much of the image is infused with wispy blue clouds showing X-rays detected by Chandra. At a few points, the wispy blue clouds seem to form into balls of teal colored light and are known as dust halos. They are caused by X-rays from bright X-ray sources reflecting off dust surrounding the sources. These dust halos resemble underwater lights glowing in a cloudy swimming pool at night. Rising up from Sagittarius A* in the center of the image is a pillar of blue light referred to as a chimney. This chimney of hot gas is surrounded by red clouds that are filled with stars, presenting themselves as tiny red flecks. Near the top of the blue pillar is a streak of light blue, outlined by an illustrated, gray box. This streak is referred to as the chimney exhaust vent. Just to our left is another illustrated box that shows the close-up image of the chimney vent as observed by Chandra.
