No 2022. gada ekonomisko sadārdzinājumu dēļ, Meteorītu muzejs ir spiests ieviest minimālo sensa apmeklējuma maksu 10,00€ apmērā! Cenšoties saglabāt plašu mūsu zinātnisko resursu pieejamību, esam priecīgi arī turpmāk 2023. gadā nodrošināt ģimenes un vairāku apmeklētāju grupas gadījumā iepriekšējās cenu atlaides!

GADA METEORĪTS
2023
Meteoriti.LV vietne tiks pakāpeniski papildināta ar plašu pamatinformāciju par meteorītiku un ar to saistitām astronomijas nozarēm. Uzzināsiet, vai "meteorīti dabā sastopami retāk par dimantiem", cik tie ir veci un kāda ir to izcelsme. Atradīsiet atbildes uz jautājumiem: Vai meteorīti ir bīstami? Kādi meteorīti atrodami Latvijā un kur tos var apskatīt? Vai Latvijā ir vērts meklēt meteorītus? Ko meteorītu izpēte pastāsta mums par Zemes un Saules sistēmas izcelšanos? Ceram, ka tas radīs vēlmi arī jums pašiem novērot Zemes kosmiskos viesus - meteorus, un, varbūt, pat kļūt par īstiem meteorītu medniekiem!
Veiksmīgu novērošanu!
