Vast general impression and the pride universe is got earth occupant with look at sky evening clear without moonlight. star sowing full appear sky likely untold jumlah-. structure and vast universe very difficult imagined human, and progres perception and human rationality about it need time for centuries.
Universe scenery description even also various. formerly nature se-mesta memodelkan as space measure far smaller than reality should. earth diameter size (12.500 km) new known in century ke- 3 (by eratosthenes), distance to month (384.400 km) century ke-16 (tycho brahe, 1588), distance to sun (around 150 million km) century ke-17 (cassini, 1672), star distance 61 cygni century ke-19, distance to century galaxy centre ke-20 (shapley, 1918), distance to galaksi-luar (1929), quasar and big bang (1965). this covering ground is still going on delivers generation.

proximate sky thing with earth month. month gravity style moves sea water ebb under the sun, uninterruptedly during bermiliar year. because orbit period and month rotation same, human under the sun not ever can see one of [the] technology unassisted month surface side to orbed month. another month side secret, new got with aviation luna 3 in the year 1959.
in the day time, sky scenery limit of blue sky and sun or too late month; at moment dawn and twilight, red sky at horizon east and west. sunlight interaction with earth sky describes coloured sky atmosphere.
sun self one between various star at galaxy. there star hotter than sun (sun surface temperature 5.800o k), like hot star (can achieve 50.000ok) that send out light more many lights ultraviolet--cahaya dangerous for life. there star cooler, more many memancar- red light and infra-red compared appear light many is used human.
human can achieve vast universe erudition limits, know allah creation never identified on earth like black hole, star netron, pulsar, star dies, star explosion nova or supernova, galaxy kernel explosion and as it. but, various phenomenon very terrible that is unlikely is juxtaposed with alive being susceptible towards damage. although such, there road for that want to try seriously to elaborate it.
