Nebula.

=== A nebula is an interstellar cloud of dust, hydrogen gas and plasma. Originally //nebula// was a general name for any extended astronomical object, including galaxies beyond the Milky Way. In these regions the formations of gas, dust and other materials 'clump' together to form larger masses which attract further matter, and eventually will become big enough to form stars. The remaining materials are then believed to form planets, and other planetary system objects. Nebula was founded by Edwin Hubble’s Tele scope. ===
