NASA Astronomy Picture of the Day
Read an astronomy image and its daily explanation.
What it is
Read an astronomy image and its daily explanation. The January 1, 2026 Auroral Corona entry explains an aurora image and gives image information.
Why it is selected
A compact caption can start a focused astronomy question rather than leaving an image unexplained.
Who it suits and when to use it
Good for science reading and class openers; describe the phenomenon before reading the caption.
Usage note
Only that entry was read; full-image downloads and reuse terms were not checked.
