An object in space that is a mixture of gas, dust, and ice is known as a comet. Comets originate from the outer regions of the solar system, such as the Kuiper Belt or the Oort Cloud, and are composed of volatile substances that can vaporize as they approach the Sun, creating a glowing coma and often a tail. This distinctive behavior makes comets fascinating subjects of study in astronomy.
It sounds like you are describing a nebula, which is a cloud of gas and dust in outer space. Nebulae can be illuminated by nearby stars, and their colors and shapes can vary depending on the composition of the gas and dust within them.
Dust can be considered a colloid because it consists of small solid particles dispersed in a gas (air). These solid particles are not completely dissolved in the gas but are suspended and evenly distributed throughout it, creating a heterogeneous mixture.
No, 'atmosphere' is NOT a change at all! It is a mixture of gasses and dust, mist or rain.
The point on the capnographic waveform that represents a mixture of alveolar gas and dead space gas is known as the "initial upstroke" or the "beginning of the expiratory phase." This occurs at the start of expiration when exhaled air first contains carbon dioxide from the alveoli, mixed with air from the conducting airways or dead space. This mixture results in a gradual rise in the capnography trace before achieving a plateau during the exhalation of primarily alveolar gas.
A comet is made of ice, rock, and dust, and as it approaches the sun, the heat causes the ice to vaporize, releasing gas and dust that forms a glowing tail. This tail is what gives comets their spectacular appearance as they travel through space.

It is mostly hydrogen and helium.

Clouds of gas and dust
A comet is an object that consists of a frozen mass of ice and dust. Comets have tails of gas and dust that form when they approach the Sun and their ice begins to vaporize.
A small object made of frozen gas and dust is called a comet. Comets are often referred to as "dirty snowballs" and travel through space in elongated orbits around the sun. When comets come closer to the sun, the frozen gases begin to vaporize, creating a glowing coma and tail.
The visible cloud of dust and gas in space is called a nebula. Nebulas are often regions where new stars are forming, and they can vary in size, shape, and color.

This gas envelope is likely the object's atmosphere. It plays a crucial role in protecting the object from space debris and radiation, and helps regulate its temperature. Additionally, it may interact with the surrounding space environment, such as solar wind.
No, a nebula is not a galaxy. A nebula is a cloud of gas and dust in space, while a galaxy is a collection of stars, gas, dust, and dark matter held together by gravity. Galaxies can contain nebulae, among other structures.
That would be a nebula, which is a large cloud of gas and dust in outer space. Nebulae are often regions where new stars are forming, and they come in various shapes and sizes.
