A brand new beautiful picture exhibits that two days after NASA’s Double Asteroid Redirection Check (DART) spacecraft slammed into the asteroid Dimorphos, the space rock had grown a tail of glowing particles extending hundreds of miles.Â
The comet-like tail is made from dust and particles was blasted from the floor of Dimorphos, a part of a double asteroid system, by the intentional impression of DART, the primary mission designed to check whether or not such a collision might divert a hypothetical asteroid threatening to hit Earth. Dimorphos’ new tail was imaged by astronomers Teddy Kareta from the Lowell Observatory and Matthew Knight from the U.S. Naval Academy utilizing the 4.1-meter Southern Astrophysical Analysis (SOAR) Telescope, on the Nationwide Science Basis-funded NOIRLab’s Cerro Tololo Inter-American Observatory in Chile.
“It’s superb how clearly we have been in a position to seize the construction and extent of the aftermath within the days following the impression,” Kareta mentioned in a statement (opens in new tab).Â

Observing the ejected materials might enable scientists to raised decide the character of the floor of Dimorphos by revealing simply how a lot materials the collision with DART ejected, the pace at which the fabric was launched and the scale of the ejected particles. This data might finally assist space businesses like NASA defend Earth from asteroid impacts as a result of a greater understanding of asteroid construction and composition helps scientists mannequin how finest to divert them.Â
The fabric within the dust path was initially ejected on Sept. 26 when DART hit Dimorphos, forming a cloud across the asteroid. The tail-like construction fashioned when radiation strain from the sun pushed the particles away from the physique of the asteroid, simply as occurs with the tails of comets as they strategy the sun from the distant reaches of the solar system.
The SOAR picture exhibits Dimorphos’ new function extending from the middle of the picture to the right-hand fringe of the picture. Utilizing Dimorphos’ distance from Earth on the time the picture was captured, the astronomers estimated the tail was round 6,200 miles (10,000 kilometers) lengthy. (Earlier than the impression, scientists estimated that Dimorphos itself was about 525 ft, or 160 meters, vast.)
SOAR will proceed to watch the aftermath of the DART impression, amassing information that can assist researchers assess how profitable this try to switch the orbit of an asteroid has been. SOAR is a key member of the Astronomical Occasion Observatory Community (AEON) of telescopes, which is devoted to nimbly following up on reviews of latest astronomical phenomena.
“Now begins the following phase of labor for the DART crew as they analyze their information and observations by our crew and different observers all over the world who shared in learning this thrilling occasion,” Knight mentioned. “We plan to make use of SOAR to watch the ejecta within the coming weeks and months. The mix of SOAR and AEON is simply what we’d like for environment friendly follow-up of evolving occasions like this one.”
