A pair of interacting galaxies. The larger of the two galaxies is slightly right of center, and composed of a hazy, bright, white center and a ring of gaseous filaments, which are different shades of red and orange. Toward the bottom left and bottom right of the ring are filaments of gas spiraling inward toward the core. At the top left of the ring is a noticeable gap, bordered by two large, orange pockets of dust and gas. The smaller galaxy to its left is made of hazy white gas and dust, which becomes more diffuse farther away from its center. To this galaxy’s bottom left, there is a smaller, more diffuse gas cloud that wafts outward toward the edges. Many red, orange, and white galaxies are spread throughout, with some hazier in composition and others having more defined spiral patterns.

Amid a field of galaxies, a repeated, elongated red galaxy forms a shape like the top of a question mark, with another galaxy positioned like the question mark’s dot. In each occurrence, another white, clumpy galaxy with an overall circular shape appears perched on top of the red galaxy. A very bright foreground galaxy appears to the right of the bottom curve of the question mark shape. To the lower right, among other galaxies, another occurrence of the galaxy pair appears, unaffiliated with the question mark shape.

What Is the Solar Wind?

An animation shows the Sun in the bottom left corner. Cascading off the Sun are lines in every direction, representing solar wind streams. As they move away, kinks form in the lines, and grow wider as they move outward.
