The DART mission will deploy a kinetic impactor to smack the small moon Dimorphos of the asteroid Didymos on the evening of Sept. 26. This is an on-orbit demonstration of asteroid deflection, a key test of NASA's kinetic impactor technology, designed to impact an asteroid to adjust its speed and path. This particular asteroid moon is NOT a threat to Earth, but is technology being explored to use for when we DO find a potentially hazardous asteroid.The Hubble Space Telescope captured these extraordinary views of the asteroid moon soon after the successful impact.For more information, visit https://nasa.gov/hubble.

NASA’s Hubble Space Telescope has determined the size of the largest icy comet nucleus ever found. And, it’s big! With a diameter of approximately 80 miles across, it’s about 50 times larger than typical comets. Its 500-trillion-ton mass is a hundred thousand times greater than the average comet.For more information, visit https://nasa.gov/hubble.

After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.For more information, visit https://nasa.gov/hubble.

TRT 2:22 NASA's Hubble Space Telescope has given astronomers their best look yet at an interstellar visitor — comet 2I/Borisov — whose speed and trajectory indicate it has come from beyond our solar system.This Hubble image, taken on Oct. 12, 2019, is the sharpest view of the comet to date. Hubble reveals a central concentration of dust around the nucleus (which is too small to be seen by Hubble).Hubble photographed the comet at a distance of 260 million miles from Earth. The comet is falling past the Sun and will make its closest approach to the Sun on Dec. 7, 2019, when it will be twice as far from the Sun as Earth.Click here for full feature about Hubble's view of comet 2I/Borisov.For more Hubble news follow us on social media:Twitter @NASAHubble Facebook NASA Hubble And Instagram look for nasa hubble For More InformationSee [https://www.nasa.gov/mission_pages/hubble/main/index.html](https://www.nasa.gov/mission_pages/hubble/main/index.html) Related pages

NASA's Hubble Space Telescope observed the farthest-discovered active inbound comet, Comet K2. K2 came from the distant Oort Cloud and is visiting our inner solar system for the first (and only) time. Since we're seeing it so far away, past the orbit of Saturn, K2 is still in its early phase of activity, likely making it the most primitive comet anyone has ever seen.Read the web story on nasa.gov.Download the Hubble images on HubbleSite.org.Read the science paper here.
