The first pictures of the immediate aftermath of NASA's first-ever experiment on Monday, which involved crashing a spaceship into an asteroid, were made public by the Italian space agency on Tuesday.
The images were taken by the agency's LICIACube micro-satellite, which had two cameras and was launched by DART a few days before impact. Just a few minutes after the collision, the little satellite flew by asteroid Dimorphos, which was the target of the impact, to gather the pictures.
The photos show what looks to be a crater and large ejecta streaks, which are surface debris on Dimorphos.

Despite the rarity of asteroid collisions, a large space rock's impact could cause significant local or regional devastation.
The intention of the impact was to alter the orbit of the moonlet asteroid Dimorphos around the larger space rock Didymos. Neither poses a threat to our planet anytime in the future. About 11 million kilometers separate the Earth from this pair of asteroids.
Before the collision, experts predicted that the DART crash would blast between 9,979 and 99,790 kilograms of ejecta into space and carve a crater on the asteroid.
More photographs of the collision's aftermath may be published since the Hubble Space Telescope, James Webb Space Telescope, and other ground telescopes were aimed at the system to observe the impact.
To precisely assess how much the impact changed Dimorphos' orbit around Didymos, weeks of observation of the asteroid pair will be necessary, according to NASA.
