APOD is Six Years Old Today
16.06.2001

Welcome to the seventh year of Astronomy Picture of the Day (APOD). Editors Robert Nemiroff and Jerry Bonnell are extremely grateful for the continued large volume of gracious e-mail and APOD submissions (and also for the "occasional" critical note!). Today we would like to offer a very sincere thank you to all.

APOD: 2025 July 1 Б Eye Sky a Dragon

What do you see when you look into this sky? In the center, in the dark, do you see a night sky filled with stars? Do you see a sunset to the left? Clouds all around? Do you see the central band of our Milky Way Galaxy running down the middle?

Diffuse starlight and dark nebulae along the southern Milky Way arc over the horizon and sprawl diagonally through this gorgeous nightscape. The breath-taking mosaic spans a wide 100 degrees, with the rugged terrain of the Patagonia, Argentina region in the foreground.

APOD: 2024 August 5 Б Milky Way Over Tunisia
5.08.2024

That's no moon. On the ground, that's the Lars Homestead in Tunisia. And that's not just any galaxy. That's the central band of our own Milky Way galaxy. Last, that's not just any meteor. It is a bright fireball likely from last year's Perseids meteor shower.

APOD: 2023 March 26 Б Wanderers

How far out will humanity explore? If this video's fusion of real space imagery and fictional space visualizations is on the right track, then at least the Solar System. Some of the video...
