This is a gif animation made up of false-colour images taken by ESA’s Proba-3 mission and NASA’s Solar Dynamics Observatory. Against a dark background, the Sun’s disc is shown in dark orange, as captured by NASA’s Solar Dynamics Observatory. A thin halo of yellow light surrounds the Sun, giving it a luminous outline against the dark background of space. This yellow outline shows the Sun’s inner corona, as captured by Proba-3. Also in yellow, three solar prominence eruptions are visible, resembling bright yellow wave-like outburst extending outwards from the Sun. First, we can see a smaller one in the top right corner, followed by a larger one in the top left and a third one in the bottom right. The whole animation lasts about 4 seconds and plays in a loop.

The cluster appears here as a large collection of brilliant white lights, each a distinct galaxy. A neon purple cloud stretches across the cluster’s crowded core. Many of the hundred-plus galaxies in the cluster are in two clumps of galaxies towards the top and bottom of center. Some are encircled by a faint glowing haze, while a few foreground stars gleam with diffraction spikes. Some of the smaller galaxies are tinted blue, orange, or red, and some appear more oblong than round, suggesting spiral shapes viewed edge-on. The neon purple cloud sits at the heart of the image, surrounding the most densely-packed part of the cluster. This cloud, which spreads vertically across the cluster, is multimillion-degree gas observed by Chandra. The two clumps of observable galaxies, and the spread of superheated gas, reveal that the Champagne Cluster is in fact two clusters in the process of colliding.

An image of space made by the Euclid telescope shows a bright barred spiral galaxy with two sweeping arms glowing in shades of blue and white against a deep black background dotted with stars. Its core is luminous. Its spiral arms curve gracefully outward to the left and down to the right, resembling a cosmic garland draped across the scene. A smaller, faint and round galaxy appears to the left of the barred spiral galaxy.
