I saw Casseopeia in the northeastern sky between two evergreen trees. I wondered, if we observe a star, are we getting photons that bounced from more distant stars and planets, perhaps even an older Earth?

Cassiopeia (constellation) (Wikipedia)Cassiopeia is a constellation and asterism in the northern sky named after the vain queen Cassiopeia, mother of Andromeda, in Greek mythology, who boasted about her unrivaled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today. It is easily recognizable due to its distinctive ‘W’ shape, formed by five bright stars.
