What you need to know
What has changed
Thailand’s winter stargazing season opens tonight, Saturday 31 October, with NARIT scheduling telescope viewing and Halloween-themed activities at five public astronomy venues.
The official programme places the opening session from 18:00 to 22:00 Thai time. It covers Princess Sirindhorn AstroPark in Mae Rim, Chiang Mai, and the regional observatories in Nakhon Ratchasima, Khon Kaen, Chachoengsao and Songkhla.
A seasonal launch with a Halloween theme
The opening is billed as “Starry Halloween x Alien Night”. A fresh 30 October report describes Chiang Mai’s mix of telescope viewing, music, themed areas and hands-on family activities.
That detailed Chiang Mai programme should not be assumed to be identical at every regional site. Check the announcement for the observatory you intend to visit before travelling.
What visitors may see
The Chiang Mai report lists targets including Saturn, the Andromeda Galaxy and the Pleiades, with telescopes of different sizes available for public viewing. Actual visibility depends on the sky and the observing arrangements on the night; the list is not a promise that every object will be visible to every visitor.
Families can also look for creative astronomy activities. NARIT’s points programme allows participants in qualifying sessions to collect points towards souvenirs, subject to the arrangements at each location.
More Saturday sessions follow
NARIT’s official calendar says the Chiang Mai Public Night programme starts on 31 October and continues on Saturdays through May 2027. It describes Public Night as free, while regional observatories continue their public services and seasonal activities.
The separate TNO Open House visits to the national observatory on Doi Inthanon have their own dates, booking limits and fee. They should not be confused with simply attending tonight’s public stargazing launch.
Before leaving home
Check NARIT’s latest venue notice for weather changes, access and activity availability. Arrange the return journey as well as the outward trip, particularly when visiting a venue outside a city centre.
Follow staff guidance around telescopes and allow others time at the eyepiece. The launch begins a longer season, so visitors unable to attend tonight can consult the official calendar for later opportunities.
