Cosmos

Cosmos came together through an extensive audition and training program run by Star Hunter Entertainment. The company modeled its system after K-pop and J-pop idol agencies. After months of evaluation on singing, dancing, rapping, and stage skills, they finalized a 13-member lineup. The group made their official debut on June 15, 2023, with the digital single Shooting Star. The release featured bright cosmic visuals and sharp synchronized choreography that immediately caught attention in Thailand.

Early promotions focused on their large group size and space concept. Three members had trained in South Korea, which helped shape their performance style. By 2024 the group expanded into sub-units. COSMOS SUN took a vocal-heavy direction while COSMOS CYGNUS leaned into dance and rap. These releases let members showcase individual strengths while keeping the collective identity strong.

Their sound has evolved from upbeat cosmic pop with EDM drops to more mature urban R&B and tropical house. Later tracks mix heavier bass, trap beats, and occasional Thai folk elements. This growth mirrors the path many T-pop acts follow as they move from bright concepts to sophisticated girl crush images. Cosmos continues to perform actively with regular digital releases and live appearances as of 2025. [edit]

Star Hunter Entertainment launched a large-scale project to create a major Thai girl group. They held nationwide auditions and brought in trainees from different backgrounds. The process lasted several months and tested vocals, dance, rap, and overall presence. The final 13 members stood out for their chemistry and range of skills. Three of them had spent time training in South Korea, adding professional polish to the team.

The company revealed the full lineup shortly before debut. They chose the name Cosmos through fan voting from a shortlist of options. The debut single Shooting Star dropped on June 15, 2023. Its music video was filmed inside a real planetarium to match the celestial theme. The high-energy choreography and space-inspired styling helped the track quickly climb Thai digital charts. [edit]

Cosmos built their early sound around bright cosmic pop. EDM drops, sparkling synths, and upbeat tempos defined their first releases. Shooting Star and Eclipse showcased this style with heavy dance beats and catchy hooks. From 2024 onward they explored new territory. Urban R&B tracks, mid-tempo grooves, and tropical house elements appeared more often. Their 2025 single Orbit added trap influences and subtle Thai folk motifs.

Lyrics often touch on self-discovery, friendship, and chasing dreams using space metaphors. Production leans on electronic elements but keeps strong focus on vocal harmonies given the large group. They emphasize equal line distribution so every member gets moments to shine. This approach sets them apart from many other large idol groups. [edit]

Cosmos has helped push T-pop further into regional consciousness. Their 13-member structure stands out in Thailand and inspires newer idol trainees. The group became youth ambassadors for Thailand’s Ministry of Culture in 2024, promoting creative industries to young people. Their futuristic concept mixed with traditional Thai design elements has influenced fashion trends among fans.

They achieved an important milestone as the first Thai girl group to chart on Korea’s Circle Chart with a non-Korean song. The track Stellar reached the top of Gaon’s international digital chart for a week. Their sold-out concert in Singapore within 18 months of debut also marked a first for T-pop girl groups. These accomplishments open doors for other Southeast Asian acts looking beyond their home markets. [edit]

Stellar, the official fandom name, reflects the group’s cosmic theme. Fans wave Cosmic Orb lightsticks that display LED galaxy patterns during concerts. The lightstick has a special mode that creates star patterns only when all 13 members perform together. Audiences often form constellation shapes with their lights during chorus moments.

Stellar Day happens once a year and focuses on charity work. Fans organize donation drives and environmental campaigns tied to the group’s space motif. They have funded billboards in Bangkok and run streaming parties that support good causes. The fandom also values the group’s emphasis on equal treatment of members and often celebrates each member’s individual strengths online. [edit]

The group’s debut concept film was shot inside an actual planetarium. Three members trained in South Korea for 18 months before the lineup formed. Sophie speaks Vietnamese, Thai, English, and Korean fluently and often handles messages for international fans. The Cosmic Orb lightstick hides a star-pattern feature that activates only with the full group on stage. Fans chose the final group name through voting among three options. [edit]
