Se soumrakem n\u00e1s upout\u00e1 velmi jasn\u00fd bod vysoko nad jihoz\u00e1padem. Nejedn\u00e1 se o hv\u011bzdu (tak jasn\u00e1 na nebi nen\u00ed), ale o planetu Venu\u0161i, v sou\u010dasn\u00e9 roli Ve\u010dernice. Venu\u0161e je po Slunci a M\u011bs\u00edci nejjasn\u011bj\u0161\u00edm objektem oblohy a nyn\u00ed pro\u017e\u00edv\u00e1me nejlep\u0161\u00ed podm\u00ednky jej\u00ed viditelnosti – zapad\u00e1 \u010dty\u0159i a p\u016fl hodiny po Slunci a v t\u011bchto dnech dosahuje nejvy\u0161\u0161\u00ed jasnosti (nastane 27. dubna).<\/h6>\n

M\u011bs\u00edc bude po \u010dtvrte\u010dn\u00edm novu postupn\u011b dor\u016fstat. V ned\u011bli dojde ke konjunkci M\u011bs\u00edce a Venu\u0161e. Jasnou Venu\u0161i a \u00fazk\u00fd srpek M\u011bs\u00edce tak ve\u010der uvid\u00edme bl\u00edzko sebe a bude to hezk\u00fd pohled.<\/p>\n

Kdo si naopak v p\u0159\u00ed\u0161t\u00edch dnech i t\u00fddnech p\u0159ivstane, odm\u011bnou mu budou t\u0159i planety viditeln\u00e9 o\u010dima: od nejjasn\u011bj\u0161\u00edho Jupitera\u00a0p\u0159es Saturn a\u017e po Mars.

Jejich viditelnost se bude zlep\u0161ovat, Jupiter se Saturnem budou v \u010dervenci vid\u011bt celou noc, Mars si na takovou p\u0159\u00edle\u017eitost po\u010dk\u00e1 do \u0159\u00edjna.<\/p>\n
