VERDICT: MIXED The viral claim is correct about what the system is and which telescope data it came from, but the "most beautiful one in the universe" superlative is subjective hype with no basis in any primary source — no scientist or agency ranks HD 110067 that way. **Claim-linked finding 1 — The system exists exactly as referenced, and NASA's TESS is the right data credit.** HD 110067 is a real star about 100 light-years away in Coma Berenices, and it hosts six "sub-Neptune" planets locked in a rare resonant chain (3:2 and 4:3 orbital ratios) that has been "performing this same rhythmic dance since the system formed billions of years ago." NASA's own Science article on the discovery states the first hints came from TESS (with the two outer planets later recovered from scattered-light-corrupted TESS data), and the peer-reviewed study in *Nature* (Luque et al., Nov. 29, 2023) confirms "the observations of six transiting planets around the bright nearby star HD 110067… follow a chain of resonant orbits." - https://science.nasa.gov/missions/tess/discovery-alert-watch-the-synchronized-dance-of-a-6-planet-system/ - https://www.nature.com/articles/s41586-023-06692-3 **Claim-linked finding 2 — The "most beautiful in the universe" ranking is not supported by any primary source, and TESS wasn't the sole discoverer.** No NASA, ESA, university, or peer-reviewed document calls HD 110067 "the most beautiful" exoplanet system; that is an opinion/superlative invented for the video. What primary sources actually say: NASA describes the resonance chain as creating "a mesmerising geometric pattern," and ESA's Cheops page calls it a rare "pristine configuration of a planetary system that has survived untouched" — scientifically remarkable, not aesthetically ranked. Additionally, the discovery attribution is slightly incomplete: TESS provided the key photometry, but ESA's Cheops satellite and ground-based observatories were essential to pinning down and confirming the six planets (NASA notes the third planet was identified "with the help of data from CHEOPS," and ESA states "Without that detection from Cheops, it would have been impossible"). Saying "using NASA's TESS" is accurate for the underlying light-curve imagery but omits that the full characterization was a TESS + Cheops + ground-based effort. - https://www.esa.int/Science_Exploration/Space_Science/Cheops/ESA_s_Cheops_helps_unlock_rare_six-planet_system - https://news.uchicago.edu/story/scientists-discover-rare-6-planet-system-moves-strange-synchrony Bottom line: If the TikTok means "a real, genuinely beautiful-to-watch six-planet system found with TESS data" — true. If it implies scientists actually rank HD 110067 as the most beautiful system in the universe — that claim appears nowhere in the primary literature and is unverifiable opinion. Hence MIXED.
