Astronomy Picture of the Day (APOD)
A daily astronomy image or video with a short explanation by a professional astronomer, with a full archive back to 1995 and a JSON API.
Three decades of the sky in one archive: every day a new image, each with a short story and links that send you down a rabbit hole.
