Photo: NASA, ESA, CSA, Cristina Thomas, Ian Wong An image of the aftermath of DART's collision with Dimorphos, the target asteroid, captured by LICIACube. In photos: An image from NASA’s James Webb Space Telescope shows Dimorphos in near infrared 4 hours after impact. The Hubble Space Telescope plans to monitor the Didymos-Dimorphos system 10 more times over the next three weeks to understand how the ejecta cloud behaves over time, so more images of the aftermath may be released.What's next: It will take weeks of observing the asteroid duo to precisely determine how much the impact altered Dimorphos’ orbit around Didymos. Before the collision, scientists estimated that DART's crash would excavate a crater on the asteroid and blast between 22,000 and 220,000 pounds (between 9,979 and 99,790 kilograms) of ejecta, into space.Large streaks of Dimorphos' surface material, also called ejecta, can be seen in the images, as well as what appears to be a crater.They will also be able to detect the durational changes in its orbit around the larger asteroid to measure the effects of the impact.

Given the huge size of Didymos and its moon, ground-based telescopes will be able to detect the asteroid very soon. The Italian space agency released the first images from LICIACube on Tuesday. The killer asteroid will be accompanied by its 500-foot-wide moon, which will be orbiting it.

The small satellite, which was produced by the Italian Space Agency, flew past Dimorphos just minutes after the crash to collect the images.

The big picture: Many of the photos were captured by the miniature satellite, LICIACube, which was equipped with two cameras and was deployed by DART several days before impact.

The asteroid duo are roughly 6.8 million miles (11 million kilometers) away from Earth.

Neither poses an immediate threat to Earth. How it works: The goal of the crash was to change the orbit of a moonlet asteroid, called Dimorphos, around a larger space rock called Didymos.

Asteroid strikes are rare, but an impact from a large space rock could cause significant citywide or regional damage.

The technology tested in the DART mission could one day be used to redirect an asteroid on a collision course with Earth.

Why it matters: NASA's undertaking - called the Double Asteroid Redirection Test (DART) - marked the first time humans have changed the course of a celestial body and was a major milestone in the space agency's planetary defense mission.

NASA on Thursday shared the first images captured by the James Webb and Hubble space telescopes of a spacecraft slamming into an asteroid in a first-of-its-kind experiment earlier this week.
