NASA was not about to miss the opportunity. capture their historic ambush of an asteroid through the eyes of its most powerful space observatories. On Thursday, NASA and the European Space Agency released new images taken by the Hubble and James Webb telescopes showing the moment. The DART spacecraft crashed into the asteroid Dimorphos.

DART was designed as humanity’s first experiment in kinetic impact mitigation, which is a lot of syllables to say that the goal was to crash a spacecraft into an asteroid to see if the collision could alter the space rock’s orbit. The technique could one day be used to protect Earth from an asteroid or comet that threatens to impact our planet.

Neither Dimorphos nor the largest asteroid orbiting the small moon, Didymos, pose any threat to us. In fact, No known asteroid poses a significant threat right now.

The effort to capture the instant of impact, as well as earlier and follow-up images of the crash site, marks the first time Webb and Hubble have made observations of the same target at the same time.

“This is an unprecedented view of an unprecedented event,” Andy Rivkin, DART research team leader, said in a sentence.


These images, Hubble on the left and Webb on the right, show observations of the Didymos-Dimorphos system several hours after NASA’s DART intentionally impacted the small asteroid.

The images are captured in different wavelengths of light, with Hubble showing the impact in visible light and Webb using an infrared instrument. The bright center of the images shows the point of impact, which maintained a high level of brightness for several hours. Also visible are plumes of material ejected from the asteroid’s surface by the collision.

“When I saw the data, I was literally speechless, stunned by the incredible detail of the ejection that Hubble captured,” said Jian-Yang Li of the Planetary Science Institute who led the Hubble observations.

Astronomers will continue to review observations and data from the event with telescopes located both in space and on the ground to get a better idea of ​​how the impact changed Dimorphos, both in structure and in terms of its path through the cosmos.
