Galaana fi Poolisii
Maal akka ta'e? Lafee, godannoo fi calaqqisonni galaana guyyaatti nurraa bu'u, fi bu'uun kunis kuulee hin milkaa'in fakkaata. Kunis karaa kuulee dhabdootaa kan katalagoorii kuulee fi akka baay'ee isaan namatti hin mul'atu nurra bu'uu, kan akka bakka ciminaa irraa gara magaalaatti.
Akka itti fayyadamtu: Suuraa ibsaa kan akka samaa keessanii fakkaatu, ykn ji'i fuula balali'insa nuffisaa. Ji'i suura samaa si'aa fiigichaaf.
Maaliif samaan siif maraaf?
Suuraa kan akka samaa bakka jiraattutti. Sa'aa tokko tokkoon kuulee Orion kan itti dhagahamuu dandeessan agarsiisa.
Bakkawwan fi jaalala kuulee kan katalaakii Yale Bright Star irraa. Bakka keessan hin galchine.
Jijjiirra
- Jijjiiramaa 1 (site'n hin-caalu) fi gara 9tti jijjiru.Gabaasa: From about 9,000 stars across the whole sky, only about 400 are left in a city centre, and only half of the sky is above you at any time.
- Suuraa Orion fi walqabatee lamaan 4 fi 8.Gabaasa: Shakkii kan beekamu itti fufuu, garuu, kuulee ciminaan kan itti mul'atan, fi Wayyaana Galaktikaa boodatti deebi'ee, bu'aa.
- On the next clear night without a Moon, go outside away from direct lights and wait 20 minutes for your eyes to adjust.Gabaasa: Fudhachaa sajoo kana kan walfakkaatu kan argee: kan tarree Bortle kee. Sajoowwaniin naannoo Orion agarsiisa; kunis akkaataa itti itti fayyadama.
