The Elephant Trunk Nebula
IC 1396 or SH2-131
IC 1396 is a large and fascinating emission nebula located in the constellation Cepheus, about 2,400 light-years from Earth12. Here are some key details about it:
Structure and Composition
Size: IC 1396 spans over 100 light-years across23, making it a vast region of glowing gas and dark dust clouds.
Central Star: The nebula is energized by a bright, bluish central star known as HD 2062673. This star’s intense radiation ionizes the surrounding gas, causing it to glow.
Dark Nebulae: Within IC 1396, there are several dark nebulae, including the well-known Elephant Trunk Nebula (IC 1396A), which is a site of active star formation14.
Observation
Interesting Facts
Star Formation: IC 1396 is a rich star-forming region, with many young stars and protostars embedded within its clouds14.
Appearance: The nebula appears as a mix of glowing gas and dark dust lanes, creating a stunning visual contrast2.

IC 1396 is located about 2,400 light-years from Earth123. This vast distance places it well within our Milky Way galaxy, in the constellation Cepheus.
IC 1396 hosts a variety of stars, including:
Young Stellar Objects (YSOs)
Protostars: These are young stars still in the process of forming. They are often found within dense regions of gas and dust1.
T Tauri Stars: These are very young stars that have recently emerged from their protostellar phase. They are characterized by strong stellar winds and variability1.
