On This Day in House! Jan. 9, 1643: ‘Ashen Mild’ found on Venus

On Jan. 9, 1643, the Italian astronomer Giovanni Riccioli noticed a bizarre glowing mild on the night time facet of Venus. He named it “The Ashen Mild of Venus.” 

Astronomers have seen it intermittently since then, whereas others who’ve appeared for it haven’t been capable of finding it. To today, nobody actually is aware of what causes the Ashen Mild.
