This pageBlink 30 SPHEREx images of one patch of sky: stars hold still, anything that jumps is moving.
A moving dot in Aquarius
A small patch of sky on the ecliptic, the path the planets follow, in the constellation Aquarius. SPHEREx photographed it again and again over two days in June 2025. Watch for the dot that jumps between frames.

The same patch, with time as the third dimension
Stack every image of this patch in the order it was taken, 36 hours from bottom to top. A star sits at the same spot in each, so it would draw a vertical line. The moving object leans across the stack: each dot is one measured position, and the faint line on the floor is the path on the sky.
