Madurga-Favieres also noted that no transiting companion had been detected there before.<\/p>\n\n<p class=\"wp-block-paragraph\">For people who\u2019ve followed the Tabby\u2019s Star mystery, this also fits the bigger picture. Citizen scientists with Planet Hunters first flagged the star in <strong>2015<\/strong> using NASA\u2019s Kepler data. The alien megastructure speculation lost momentum later, once follow-up observations showed that more blue light was being blocked than red. In 2016, astronomer Tabetha Boyajian raised more than $100,000 through <a href=\"https:\/\/kickstarter.en.softonic.com\/\" rel=\"noopener\">Kickstarter<\/a> for follow-up work. And over time, other ideas, from comet swarms to a destroyed exomoon, stellar changes, and a nearby companion, have more and more given way to explanations built around dust and debris.<\/p>\n\n<p class=\"wp-block-paragraph\">You can read the new findings in the latest study, though the paper is careful on one point: a single transit still doesn\u2019t confirm the <strong>planet<\/strong>.<\/p>","protected":false},"excerpt":{"rendered":"<p>A new study on KIC 8462852, better known as Tabby\u2019s Star, has just come out, and it points to a possible giant planet that could help explain the star\u2019s long-running, irregular fading.
