The biggest explosions in the universe, ranked

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.
