A slew of rocky material was smashing together in a maelstrom that would eventually become the baby protoplanets, comets and asteroids that make up our cosmic neighborhood.<\/p>\n And now NASA\u2019s Hubble Space Telescope has captured a similar violent clash occurring around another star some 25 light-years away. The star, Fomalhaut, stands out as one of the brightest in the night sky and is known to be shrouded in bands of dust and debris.<\/p>\n Back in 2008 astronomers examining Fomalhaut discovered a potential planet orbiting the star\u2014subsequent observations, however, showed that the orb was fading, leading some to question whether it was a planet or the debris left over from a collision between two smaller objects. By 2014 it had disappeared. And in a new study published in Science, astronomers describe how, in 2023, they found a different point of light that resembles the previously discovered object.<\/p>\n If you’re enjoying this article, consider supporting our award-winning journalism by subscribing.

The observations cut against older hypotheses about such crashes, according to Paul Kalas, an astronomer at the University of California, Berkeley, and a co-author of the new study.<\/p>\n \u201cPrevious theory suggested that there should be one collision every 100,000 years, or longer. Here, in 20 years, we\u2019ve seen two,\u201d Kalas said in a statement. \u201cIf you had a movie of the last 3,000 years, and it was sped up so that every year was a fraction of a second, imagine how many flashes you\u2019d see over that time. Fomalhaut\u2019s planetary system would be sparkling with these collisions.\u201d<\/p>\n In the future, Kalas and his colleagues hope to use the James Webb Space Telescope to glean the composition of the dust left over from the crash, including any evidence it contains water ice. These and other observations of Fomalhaut and its surrounding debris could offer new clues to how planetary systems like our own coalesce and evolve.<\/p>\n If you enjoyed this article, I\u2019d like to ask for your support.
