The nebula is one of the largest diffuse nebulae in our skies.

It contains many dark nebulae in addition to the emission diffuse nebulae.

Higher density regions of the interstellar medium form clouds, or diffuse nebulae, where star formation takes place.

This hinders the galaxy from forming diffuse nebulae except through mergers with other galaxies.

Shetland had watched diffuse nebulae coalesce into thick dust clouds that gave birth to bright new star clusters.

Diffuse nebulae.

Most nebulae can be described as diffuse nebulae, which means that they are extended and contain no well-defined boundaries.

Interstellar dust is found between the stars, and high concentrations produce diffuse nebulae and reflection nebulae.

Bright and dark diffuse nebulae are shown, and the actual outlines of those larger than 10' in diameter are painstakingly drawn.

Reflection nebulae and emission nebulae are usually seen together and sometimes are called diffuse nebulae.

An Orion variable is a variable star which exhibits irregular and eruptive variations in its luminosity and is typically associated with diffuse nebulae.

Maffei found Maffei 1, together with its companion spiral galaxy Maffei 2, while searching for diffuse nebulae and T Tauri stars.

According to Dr. Samuel Lewis Ziegler, indications for this purpose might include albinism, aniridia, coloboma, iridodialysis, keratoconus, or diffused nebulae of the cornea.

Slipher and Edwin Hubble continued to collect the spectra from many diffuse nebulae, finding 29 that showed emission spectra and 33 had the continuous spectra of star light.

However, because of this fact, there are few open clusters (except for the Coma Berenices Cluster, which dominates the northern part of the constellation), diffuse nebulae, or planetary nebulae.

He provided spectral characteristics, luminosities and dimensions for the five brightest "diffuse nebulae" (giant H II regions) that included the Bubble Nebula and the Ring Nebula.

In contrast to spirals, an elliptical galaxy loses the cold component of its interstellar medium within roughly a billion years, which hinders the galaxy from forming diffuse nebulae except through mergers with other galaxies.

The Messier catalogue comprises nearly all the most spectacular examples of the five types of deep sky object - diffuse nebulae, planetary nebulae, open clusters, globular clusters and galaxies - visible from European latitudes.

There is now little dust remaining to form the diffuse nebulae where new stars are created, so the stellar population is dominated by old, population II stars that contain relatively low abundances of elements other than hydrogen and helium.

Here he wrote a famous paper, An Application of the Quantum Theory to the Luminosity of Diffuse Nebulae, which for the first time provided a quantitative method (the "Zanstra method") for understanding the luminosity of nebulas and comets.

Let us start with an initial very large diffuse nebula.

A typical diffuse nebula is a few hundred light-years across.

The expanding shell of gas forms a supernova remnant, a special diffuse nebula.

Spock had chosen to conceal the powerful sensor relay next to a small diffuse nebula.

Binoculars are great for wide field, bright observations of the emission and diffuse nebula in our Milky Way Galaxy.

A lane of cooler dust connects NGC 1748 to a larger more diffuse nebula seen on the right.

This star is surrounded by a diffuse nebula called IC1318, or the Gamma Cygni region.

Because the device was triggered in a diffuse nebula of highly charged gas and radioactive debris, the result was a highly unstable planet.

Reflection nebulae and emission nebulae are usually seen together and sometimes are called 'diffuse nebulae'.

NGC 1579 (also known as the Northern Trifid) is a diffuse nebula located in the constellation of Perseus.

The Orion Nebula, also known as M42, is a diffuse nebula situated south of Orion's Belt in the constellation of Orion.

Slipher and Edwin Hubble continued to collect the spectra from many diffuse nebulae, finding 29 that showed emission spectra and 33 had the continuous spectra of star light.

August is also a great time to see the wonders of the central Milky Way directly overhead at Grove Creek Observatory with wonderful globular clusters and stunning diffuse nebula, so we will be showing other celestial wonders as well.

Here he wrote a famous paper, An Application of the Quantum Theory to the Luminosity of Diffuse Nebulae, which for the first time provided a quantitative method (the "Zanstra method") for understanding the luminosity of nebulas and comets.

Look in particular for the complicated Tarantula Nebula (30 Doradûs), which is the most brilliant part of the whole Cloud and can be identified even with the naked eye: it is the largest known diffuse nebula, and if it were as close to us as M42 in Orion it would cast strong shadows.
