Three days ago, NASA’s DART spacecraft slammed into asteroid Dimorphos at 14,000 mph.
The dramatic impact expelled a cloud of dust and turned the asteroid into a type of comet.
“Dimorphos now has a tail,” reports Ernesto Guido who photographed the structure during the early hours of Sept. 28th:
“This shows the asteroid about 29 hours after impact,” says Guido, who used a remotely-controlled 0.61-m telescope in El Sauce, Chile. “It developed a beautiful narrow tail 80 arcseconds long.”
When NASA’s DART spacecraft slammed into asteroid Dimorphos on Sept. 26th, almost every telescope in the Solar System was watching. Here is what Hubble saw:
In these visible-light images, the asteroid tripled in brightness after DART struck. The glow remained steady for more than eight hours after impact.
Oh, and Webb saw it too.
