Meet Sh 2-140, a beautiful H ii region that lies on the southeast edge of Lynds 2304 — a dark nebula. Also pictured nearby is the star cluster, dubbed a [IC 1396](<http://antwrp.gsfc.nasa.gov/apod/ap050908.html>) (also known as [Trumpler 37](<http://simbad.u-strasbg.fr/simbad/sim-id?Ident=trumpler+37&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id>)), which, in turn, is situated near the edge of the [Cepheus bubble ](<http://simbad.u-strasbg.fr/simbad/sim-id?Ident=Cepheus+bubble&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id>)(this immensely large expanding shell of interstellar materials, like gas and dust, surrounds something called the [Cep OB2](<http://simbad.u-strasbg.fr/simbad/sim-id?Ident=Cep+OB2&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id>) association). The [whole lot](<http://apod.nasa.gov/apod/ap100909.html>), including the famous [Elephant's Trunk nebula](<https://futurism.com/apod-elephants-trunk-nebula>), can be found about 3,000 light-years from Earth in the constellation of Cepheus.
