Gealach de chuid Iupatair i Europa , agus i ar an seachtu satailit is congarai don phlainead sin. Ceann de Ghealacha Galileo ata ann, is e sin, na gealacha a d'aithin Galileo Galilei roimh aon duine eile sa bhliain 1610 . Is i Europa an ceann is lu den cheathrar seo.

Ta se de chuma ar Europa nach bhfuil ann ach liathroid oighir , ach le firinne, creideann na saineolaithe go bhfuil forsai imtharraingthe Iupatair agus na ngealach eile ag coinneail an uisce leaite faoi dhromchla na gealai seo, ionas gur feidir go bhfuil farraige iomlan istigh ansin. Tathar ag deanamh, fiu, go bhfeadfadh miocrorganaigh a bheith beo san fharraige sin.

Fuair Europa a hainm o Simon Marius , an realteolai Gearmanach a thug le fios gurbh eisean, seachas Galileo, ba thuisce a chonaic an ghealach. Ni raibh na realteolaithe sasta na hainmneacha a thug Marius ar na gealacha a usaid, agus ar feadh i bhfad, thugaidis "Iupatar a Do" ar Europa, agus iad ag baint usaide as coras ainmnithe na ngealach a bhi ceadcheaptha ag Galileo fein. Mar sin, nior eirigh "Europa" coitianta mar ainm ach san fhichiu haois.

Ta Europa ainmnithe as "Europa", inion Agenor i miotaseolaiocht na Greige. B'e ri na Tire e, mar Agenor. Seanchathair Fheiniceach i an Tir ata suite i Liobain an lae inniu. Deirfiuir le Cadmus ab ea Europa freisin - b'e Cadmus a bhunaigh an Teib sa Ghreig .

Ta reigiun ar Europa ata ainmnithe as Conamara in Eirinn - Conamara Chaos . Is e is bri le chaos sa chomhtheacs seo na reigiun a bhfuil cuma anorduil ( chaotic ) air.
