A Lua está na fase Nova nesta quinta-feira. Ela aparece muito pouco no céu, marcando o início de mais um ciclo lunar.

Nesse momento, a Lua se posiciona entre a Terra e o Sol. Por isso, sua parte iluminada fica voltada para longe da nossa visão.

Nos próximos dias, um pequeno arco luminoso começará a surgir. A fase Crescente chega em 23 de maio.

Todo ciclo da Lua leva, em média, 29 dias e meio. Durante esse período, o satélite muda sua aparência no céu.

Maio de 2026 terá um detalhe especial: duas luas cheias no mesmo mês. A primeira ocorreu no início de maio. A próxima será no dia 31.

As fases lunares são observadas há milhares de anos. Elas ajudam a entender os movimentos do espaço e continuam despertando curiosidade até hoje.
