I am a native in this world And think in it as a native thinks

Astronomy Tuesday

A slightly different sunrise than the ones I saw a few days ago.

At the South Pole, the sun should make its first appearance after the long winter at the equinox, but because of the lensing effect of the Earth's atmosphere, the first sliver appears a few weeks early. And once it finally emerges, it takes its time -- the sunrise can take up to two weeks.
