The images were captured simultaneously by two massive space telescopes
America’s space agency has released a series of photos showing the aftermath of a “planetary defense” experiment which aimed to knock an incoming asteroid off course, with giant plumes of material seen flying off the object after a deliberate collision with a spacecraft.
NASA issued the images on Thursday, revealing early results of the Double Asteroid Redirection Test (DART) conducted earlier this week, what the space agency deemed the “world’s first test of the kinetic impact mitigation technique, using a spacecraft to deflect an asteroid.” The photos were taken by the Hubble Space Telescope and the newer James Webb Space Telescope, also marking the first time the two observatories captured the same celestial body simultaneously.
“When I saw the data, I was literally speechless, stunned by the amazing detail of the ejecta that Hubble captured,” said Jian-Yang Li of the Planetary Science Institute in Tucson, Arizona, who led the Hubble team’s observations, referring to the plumes of material thrown from the asteroid Dimorphos. “I feel lucky to witness this moment and be part of the team that made this happen.”

Earlier this week, @NASA intentionally crashed a spacecraft into Dimorphos, a non-threatening asteroid moonlet in the double-asteroid system of Didymos, in a test of planetary defense: https://t.co/pe2qeFDYoS pic.twitter.com/VQ5X1pQlEy

Dimorphos can be seen to grow increasingly brighter in images captured 22 minutes, 5 hours and 8.2 hours after DART’s impact, with huge clouds thrown from its surface appearing to glow a pale blue in visible light.
