Horsehead Nebula

[4] Using NASA's James Webb Space Telescope, astronomers have captured the nebula's "mane" in unprecedented detail, revealing the complexity of the photodissociation region where ultraviolet light interacts with gas and dust.

[5][6] The nebula was discovered by Scottish astronomer Williamina Fleming in 1888 on a photographic plate taken at the Harvard College Observatory.

Magnetic fields channel the gases, leaving the nebula into streams, shown as foreground streaks against the background glow.

[10] A glowing strip of hydrogen gas marks the edge of the enormous cloud, and the densities of nearby stars are noticeably different on either side.

[13] The visible dark nebula emerging from the gaseous complex is an active site of the formation of "low-mass" stars.
