NASA has released new photos of the Hartley 2 comet, up-close, high-resolution images of the approximately 1.4-mile-long comet core.
The images, taken millions of miles from Earth, show the comet somewhat resembling a peanut or chicken drumstick, NPR reports.
NASA Mission Scientist Don Yeomans observed about the comet, "It's hyperactive, small and feisty."
The AP reports that Hartley 2 passed within 11 million miles of Earth on Oct. 20 -- the closest it has been to our planet since its discovery in 1986.
