This figure illustrates how an interstellar object is rapidly approaching our solar system. Ejected from its home planet system long ago, the object traveled through interstellar space for billions of years before passing briefly in our cosmic neighborhood. The Robin Observatory will reveal many of these unknown interstellar visitors.

When the DART spacecraft crashed into the dimorphous asteroid, the body of the spacecraft hit between two large rocks and the two solar panels hit the rocks themselves. The yellow surface is a digital ground model of the impact site prepared from DART images, and the image of the DART spacecraft shows its position a few tens of milliseconds before impact. The white line coming out of the back of the spacecraft shows the trajectory of the spacecraft. The length of the spacecraft's body was about 1.30 meters from front to back.

These dark spots on the Sun, visible in ultraviolet light, are called coronal holes and are areas where fast solar wind bursts out into space. By chance, they managed to take a photo that looked like the sun was smiling.
