Sh2-171 – The Question Mark Nebula in Cepheus. A two-panel mosaic covering over 100 light-years of active star formation, powered by Berkeley 59 — a cluster just 2 million years old. Its O5V star BD+66 1673 burns at 45,000 Kelvin, sculpting the dark pillars visible throughout the frame. Processed in Hubble Palette (HSO).

The Question Mark Nebula
====================

2,600 light-years away in Cepheus, a cosmic question mark is being written in gas and dust. Sharpless 171 (NGC 7822) is an active stellar nursery spanning over 100 light-years, powered by Berkeley 59 — a star cluster just two million years old. Its brightest member, BD+66 1673, burns at nearly 45,000 Kelvin, sculpting the surrounding cloud into the elephant trunks and dark pillars you see here. A two-million-year-old star carving a hundred-light-year nebula. The universe doesn't do things small.

The foreground scatter of stars in the upper part of the frame belongs to NGC 7762 — an unrelated open cluster that is 2.5 billion years old and just happens to share the same patch of sky. Ancient stars looking on as new ones are born.

Two-panel mosaic captured over two nights from Chemnitz, processed in Hubble Palette (HSO). 🔭
