Cocoon Nebula (IC5146) and Dark Nebula B168 in Cygnus
This faint emission nebula is located 2°20' SSE of p2 Cygni (see finder chart below). A 2° long complex of dark filaments extending NW and W of Cocoon corresponds to B168 dark nebula.

Magnetic cocoon. MESSENGER found Mercury's magnetic field to be different from the Mariner observations.
The cocoon of gas and dust surrounding them blocks the visible light. The surrounding dust warms up enough to produce copious amounts of infrared and the cooler dust further out glows with microwave energy.

Apparently, some of the stars are already so hot that they emit large amounts of ultraviolet radiation, which is mostly absorbed by a "cocoon" of dust surrounding the central star.
Stars are born within cocoons of dust and dense molecular gas, and are mostly hidden from view at visible wavelengths.
Minutes later, its airbag-cocooned lander bounced to a stop on the Martian surface. The Pathfinder Lander, now known as the Sagan Memorial Station, carried onboard a robotic rover named Sojourner.

The H-beta filter transmits only the H-beta emission line and is only useful on a handful of objects, with the most popular being the Horsehead nebula, the California nebula, and the Cocoon nebula.
It is only when the radiation pressure from a star drives away its 'cocoon' that it becomes visible.
The term planetary nebula is a misnomer; dying stars create these cocoons when they lose outer layers of gas. The process has nothing to do with planet formation, which is predicted to happen early in a star's life.
NGC 4485 and NGC 4490 are two splendid galaxies in the same field: 4485 is more compact (this one is sometimes called the Cocoon Galaxy), while 4490 is larger and brighter. Located less than one degree northwest of beta CVn.
First the star begins to condense from inside but generally near one edge of a dense molecular cloud, or "cocoon." This condensation initiates a period of contracting and internal heating followed by a long period as a main-sequence star.

It grows by accretion as the surrounding matter falls toward it, attaining stellar mass within 105 years after it forms. At this stage, it is a protostar - a large cocoon of contracting matter that is radiating predominantly in the far infrared.

Note that jet simulations indicate that the visible sources are probably surrounded by a cocoon, including backwards-flowing material, which is only seldom detectable.
