An asteroid-circling spacecraft has captured a cool snapshot of home.
NASA's Osiris-Rex spacecraft took the picture days before going into orbit around asteroid Bennu on New Year's Eve.
The tiny asteroid—barely one-third of a mile (500 meters) across—appears as a big bright blob in the long-exposure photo released last week. Seventy million miles (110 million kilometers) away, Earth appears as a white dot, with the moon an even smaller dot but still clearly visible.
Osiris-Rex is the first spacecraft to orbit such a small celestial body, and from such a close distance—about a mile (1,600 meters) out.
Next year, Osiris-Rex will attempt to gather some samples from the carbon-rich asteroid, for return to Earth in 2023.
Osiris-Rex launched from Florida in 2016.
