NASA’s APOD Showcases the 20‑Light‑Year‑Long Elephant’s Trunk Nebula in Cepheus

On August 20 2026, NASA’s Astronomy Picture of the Day (APOD) featured the Elephant’s Trunk Nebula, a striking 20‑light‑year‑long structure within the IC 1396 emission region of the Cepheus constellation. The nebula, also known as vdB 142, lies roughly 3,000 light‑years from Earth and is part of a young star‑cluster complex that spans over five degrees of sky. The high‑resolution image reveals bright, swept‑back ridges and pockets of cool interstellar dust and gas. The dark, tendril‑shaped clouds contain the raw material for star formation and hide protostars, offering a vivid glimpse into the early stages of stellar birth. The view covers nearly one degree of the sky—just under the angular size of two full moons—highlighting the nebula’s impressive scale.
