A faint, cloudlike, self-luminous mass of matter situated beyond the solar system among the stars. The term was originally applied to any diffuse luminous region. Now, technically, it is applied to interstellar clouds of dust and gases (diffuse nebula). However distant galaxies and very distant star clusters often appear like them in the telescope, such as the spiral nebula in Andromeda, known now to be a distant galaxy.
Cloud of glowing gas in space, lit up by hot young stars within it.
A generic term for a fuzzy, diffuse astronomical object. Astronomers have observed four different types of nebulae: H II regions, reflection nebulae, planetary nebulae, and supernova remnants. See also: supernova remnant
A spread-out cloud of interstellar dust or gas.
An immense cloud of dust and gas, composed mainly hydrogen, in interstellar space.
A giant cloud of gas and dust in the universe
(plural=nebulae) A mass of gas and dust in space. This image is the Crab nebula.
cluster of stars, or a cloud of dust particles and gases.
Bright or dark cloud of gas and dust, which may contain stars.
A large cloud of gas and dust in space. Most are dark and obscure the light from background stars. Others glow brilliantly from the energy of hot star within them.
A cloud of interstellar dust that is faintly visible from Earth.
An immense, diffuse body of interstellar gas and dust that has not condensed into a star.
This term is used in astronomy to describe fuzzy patches seen in the sky! Nebulae are often vast clouds of dust and gas - some are remnants of a supernova explosions, others are stellar maternity units, where young stars are born.
A large cloud of gas and dust in space, much smaller than a galaxy. They can actually be a star producing region. They can emit, reflect, and/or absorb light and radiation from nearby stellar radiation. Ex. M42 - The Orion Nebula.
rarefied cloud of gas or dust observed in interstellar space.
Latin for 'cloud'. A fuzzy, or cloudlike patch in the sky. Nebulae (plural form) may be dark clouds of interstellar material which obscure the stars behind them, glowing clouds of heated interstellar gas, clouds of dust reflecting the light of nearby stars, or groups of stars (clusters or galaxies) which are simply too far away to see as individual objects.
(plural: nebulae) tenuous cloud of gas and dust in interstellar space
A term used to describe celestial objects which have a fuzzy or cloudy appearance. Nebula is Latin for cloud.
Cloud of interstellar gas or dust.
The term originally applied to any extended (i.e., fuzzy, non-stellar) object in the sky. More recently, it is used to describe clouds of gas in space. Some nebulae are illuminated by nearby stars (bright nebulae), while others remain dark and are only seen if they obscure a brighter object (dark nebulae).
A region of gas and dust in a galaxy. They appear to be fuzzy.
Nebulae (plural of nebula) are large interstellar clouds of dust and gas. There are two main types of nebula: diffuse nebulae and planetary nebulae. You can find more information at The Columbia Encyclopedia. Be sure to check out some spectacular Hubble Space Telescope photos of nebulae.
A cloud of interstellar gas. One of the most famous nebula is the Great Orion Nebula, which can be seen with the unaided eye. It is the middle 'star' of the sword of Orion. For excellent nebulae pictures, check out HST Images. The Great Orion Nebula
A cloud of hydrogen gas and carbon and silicate dust in space. Nebulae can be very large, spanning 100s of light years. They tend to be either red, green, or blue, depending on whether we are seeing the hydrogen, oxygen, or scattering off of interstellar dust.
a large cloud of gas and dust in space that is the beginning of a star outer planets - the five planets farthest from the Sun - Jupiter, Saturn, Uranus, Neptune, Pluto.
an interstellar diffuse cloud of dust particles and gases.
(pl. nebulae) cloud of interstellar gas and dust. (This term was also formerly applied to objects now called galaxies.) There are two basic types: bright (which include both emission nebulae and reflection nebulae) and dark nebulae ( absorption). Nebulae are also categorized by form including diffuse nebulae (often "protostellar nebulae"), planetary nebulae and supernova remnants.
A diffuse collection of interstellar dust and gas.
a cloudlike group of stars, too far away to be seen singly
a cloud of intergalactic dust, consisting of up to several thousand micrometer-sized grains per cubic kilometer of space
a diffuse mass of interstellar dust or gas, or both, visible as luminous patches or areas of darkness depending on the way the gas and dust absorb or reflect radiation
a dust and gas cloud formed fundamentally by hydrogen, the more abundant chemical element in the universe
a interstellar gas cloud
a mass of dust or gas between stars that can either appear as patches of light or dark depending on whether it absorbs or reflects radiation from the stars
a small star
a vast cloud of gas and dust
A term used by optical astronomers to denote any object that resembles a cloud, either bright or dark, and is not stellar in appearance.
a collection of gas and/or dust
(Latin for "Cloud") A cloud of interstellar cloud or dust.
derived from the Latin word for "cloud," a fuzzy patch of light in the night sky. Nebulae appear in many forms and are thought to be clouds of dust and gas, frequently the remains of exploded stars.
Any one of dim, fizzy, non-stellar objects usually illuminated clouds of dust and gas in space.
A cloud of gas or dust in space, either between the stars or expelled by a star. There are many kinds of nebulae.
Originally referring to any fuzzy celestial object, it now applies to any cloud of interstellar gas and dust, either luminous (emission) or dark (absorption).
A huge cloud of gas and dust in space.
A cloud of interstellar gas and dust. The term was formerly also used for objects now know to be galaxies (e.g. the “great nebula” in Andromeda, now usually called the Andromeda Galaxy).
An interstellar cloud of dust and gas. Often solar systems form when something causes these clouds to coalesce. These can be formed by the death of a star.
A term used to describe celestial objects which have a fuzzy, or nebulous, appearance (from the Latin for cloud.), such as gas, or dust, clouds. Galaxies were once described thus.
An immense cloud-like mass of interstellar gas and dust, generally in the spiral arms of a galaxy.
a cloud of interstellar gas and dust; some nebulae represent stellar nurseries, others represent stellar graveyards
A cloud of dust and gas in space, usually illuminated by one or more stars. Nebulae represent the raw material the stars are made of.
An area of dust and gas in space. A nearby star can make a nebula shine, either through reflected starlight, or because energy from the star makes the nebula itself glow. The plural is nebulae.
bright or dark mass of interstellar gas and dust among the stars
The breeding ground for new stars. Cluster of glowing matter pulled together by gravity.
A low density cloud of gas and dust in which a star is born. OORT CLOUD A huge cloud which is thought to surround our solar system and reach over halfway to the nearest star. Comets originate in the Oort Cloud.
a cloud of interstellar gas and dust made up mostly of hydrogen and helium. Nebulas come in different forms; planetary nebulas, supernova remnants, and diffuse nebulas. When stars form, they form as a result of a nebula condensing
A large, deep-space object comprised of gas and dust. A nebula that glows with its own light is called an emission nebula while one lit from nearby stars is called a reflection nebula. A nebula that blocks light is called a dark nebula.
A cloud of gas, dust, or both, often charged to glow by the energetic radiation of hot stars near it.
This is a cloud of dust and gas inside a galaxy. Nebulae become visible when the gas begins to glow or if a nearby star is reflected against the cloud.
the name indicates a generic mass of gas, more or less rarefied, and dust. There are many kinds of Nebulae, with different origins. They can be dark, or they can have a luminous source in the centre (like the stars), or they can reflect the light coming from an external source. The Protosolar Nebula is the cloud of primordial gas from which the Solar System originated, by gravitational contraction.
A glowing cloud of gas or dust reflecting the light of nearby stars. Here is an example of the ring nebula taken here with the Ultima 2000 telescope and a CCD camera.
An immense cloud of gas (mainly hydrogen) and dust in interstellar space.
(Latin for "cloud") A cloudof interstellar gas and dust.
An interstellar cloud of gas and dust.
A diffuse mass of interstellar dust and gas.
General term used for any "fuzzy" patch on the sky, either light or dark.
A cloud of dust and gas in space. Some are luminous and some nebulae are dark.
Any of many immense bodies of highly rarefied gas or dust in interstellar space.
any of numerous clouds of gas or dust in interstellar space. SF - a galaxy other than the Milky Way
Latin for "cloud." Bright nebulas are great clouds of glowing gas lit up by stars inside or nearby. Dark nebulas are not lit up and are visible only because they block the light of stars behind them.
A cloud of gas and dust lying between the stars. Some are bright whilst others are dark. Bright ones shining because of reflected light are called reflection nebulae. Bright ones shining because the gas is exited by radiation from nearby stars are called emission nebulae. Dark nebulae appear like holes in the starry background because they are not illuminated by nearby stars. Nebulae are often the birthplaces of stars.
A nebula (Latin: "mist"; pl. nebulae or nebulÃ¦, with ligature; from Greek nephele, "cloud") is an interstellar cloud of dust, gas and plasma. Originally nebula was a general name for any extended astronomical object, including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy is sometimes referred to as the Andromeda Nebula).
