This groundbreaking finding is the most ancient galaxy of its kind every observed and the discovery of a galaxy with a spiral structure at such an early stage is crucial evidence in being able to resolve the long unanswered question of astronomy: \u201cHow and when did spiral galaxies form?\u201d<\/p>\n
\u201cI was excited because I had never seen such clear evidence of a rotating disk, spiral structure, and centralised mass structure in a distant galaxy in any previous literature,\u201d said Takafumi Tsukui, a graduate student at SOKENDAI and the lead author of the research paper published in the journal Science. \u201cThe quality of the ALMA data was so good that I was able to see so much detail that I thought it was a nearby galaxy.\u201d<\/p>\n
Spiral galaxies, such as the Milky Way, are essential objects in the Universe, accounting for up to 70% of the number of galaxies in the Universe. Interestingly, some research has indicated that the ratio of spiral galaxies decreases quickly when looking back through the history of the Universe. This, therefore, raises the question of when exactly the spiral galaxies were formed.<\/p>\n
Tsukui, together with Satoru Iguchi, his supervisor and professor at SOKEDAI and NAOJ<\/a> observed a galaxy called BRI 1335-0417 in the ALMA Science Archive. This galaxy existed 12.4 billion years ago and contained a big quantity of dust, which obscures the starlight, thus making it challenging to examine the galaxy precisely and with visible light.<\/p>\n
