Milky Way season in Athens

The bright core of the Milky Way stays low, so you need a clear southern or northern horizon. It climbs at least 20° above the horizon during astronomical darkness in April, May, June, July, August, peaking in June at about 23°.

• The north celestial pole stands 38° above the horizon, so stars within 38° of it never set from here.
• About 80.8% of the whole sky rises above the horizon at some point in the year from this latitude.
• The Milky Way's core in Sagittarius culminates about 23° up, staying low, so a clear southern horizon matters.
• At 70 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
