A few weeks ago NASA's DART mission crashed into an asteroid. Followup observations from Hubble show a surprising finding: the asteroid now has a second tail. A few weeks ago NASA's DART mission crashed into an asteroid. Followup observations from Hubble show a surprising finding: the asteroid now has a second tail. Such tails are more commonly associated with comets (made of ice and dust) than asteroids (made primarily of rock). As comets typically travel around the sun in elliptical orbits, they come closer to the sun at some times than at others. As a comet approaches the sun, it heats up and gives off dust and gas which forms a distinctive tail. In the case of the Dimorphos asteroid, the tails are composed of material thrown up by the DART impact called ejecta. The first tail from Dimorphos was observed a few days after the initial impact on September 26 as debris was left behind the asteroid. But as Hubble continued to observe the asteroid with a series of 18 observations, researchers saw a second tail form between October 2 and October 8. Read more:

NASA’s Double Asteroid Redirection Test, or DART , mission crashed a probe into space object in September. For a moment I thought it was video-copilot's optical flare! Hi videocopilot 😊 What is the course this asteroid is on? Impact images show ejecta spewing in half a dozen or more directions. If it’s still boiling off from the impact site, the ejecta streams should form the usual cometary two tails due to solar wind interaction with gas (small-blows straight) and dust (heavier-follows the orbit).

Asteroid NASA Smashed a Spacecraft Into Grew Two 'Unexpected' TailsNASA has announced that after successfully smashing its Double Asteroid Reduction Test ( DART ) into an asteroid, the space rock ejected two comet tails. Hubble captures an 'unexpected' twin tail produced by NASA's spacecraft asteroid impactThe DART mission successfully altered Didymos' motion, meaning NASA has a working planetary defense system on its hand. A few weeks ago NASA’s DART mission succeeded in changing the orbit of the Dimorphos asteroid in a first-of-its-kind test of potential planetary defense systems.that DART was successful and shortened Dimorphos’ original 11-hour and 55-minute orbit around Didymos by about 32 minutes.Sign up for CNN’s Wonder Theory science newsletter.Asteroid impact: Here's the last thing NASA's DART spacecraft saw before it crashed If the asteroid itself is the center of a clock, DART came in from 10 o'clock. The DART spacecraft deliberately crashed into the asteroid and the impact was observed by telescopes around the world, including the James Webb and Hubble space telescopes. Now, follow-up observations from Hubble show a surprising finding: the asteroid now has a second tail. The observations show that the ejected material, or “ejecta,” has expanded and faded in brightness as time went on after impact, largely as expected. Such tails are more commonly associated with comets (made of ice and dust) than asteroids (made primarily of rock). The image, released Thursday, is one of 18 observations that the Hubble telescope has made of the Didymos-Dimorphos asteroid system since NASA’s Double Asteroid Redirection Test, or DART, mission crashed a probe into Dimorphos in September. As comets typically travel around the sun in elliptical orbits, they come closer to the sun at some times than at others. The latest Hubble observations provide the best-quality image of the double-tail to date. As a comet approaches the sun, it heats up and gives off dust and gas which forms a distinctive tail. 8, the NASA statement notes. In the case of the Dimorphos asteroid, the tails are composed of material thrown up by the DART impact called ejecta. At the top right of the image, there are arrows indicating the direction of impact by the DART spacecraft. “The twin tail is an unexpected development, although similar behavior is commonly seen in comets and active asteroids. The first tail from Dimorphos was observed a few days after the initial impact on September 26 as debris was left behind the asteroid. But as Hubble continued to observe the asteroid with a series of 18 observations, researchers saw a second tail form between October 2 and October 8. The ‘to Sun’ arrow points in the 8 o’clock direction. “Repeated observations from Hubble over the last several weeks have allowed scientists to present a more complete picture of how the system’s debris cloud has evolved over time,” Hubble scientists write. NASA noted that it’s the northernmost tail that was newly created, and scientists will use data from Hubble in the coming months to examine more closely how it may have formed. “The observations show that the ejected material, or ‘ejecta,’ has expanded and faded in brightness as time went on after impact, largely as expected. Imagery indicates the second tail formed between October 2 and October 8. The twin tail is an unexpected development, although similar behavior is commonly seen in comets and active asteroids. The Hubble observations provide the best-quality image of the double-tail to date. The north arrow points directly straight up. But NASA revealed this month that it was able to cut its trajectory down by 32 seconds — from an orbit of 11 hours and 55 minutes to 11 hours and 23 minutes.” As this is the first time such an impact has been observed, there is a lot we still have to learn about the long-term effects on the asteroid and its orbit. Researchers will continue to look at the Hubble data on the asteroid to gather more information about it, and the European Space Agency will launch its Hera mission in 2024 to visit the asteroid system and see the effects of the impact up close.
