A nebula (Latin for 'cloud, fog'; pl.: nebulae, nebulæ, or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized...

Pelican Nebula (also known as IC 5070 and IC 5067) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions...

visible dark nebula emerging from the gaseous complex is an active site of the formation of "low-mass" stars. Bright spots in the Horsehead Nebula's base are...

The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula) is a young open cluster of stars in the constellation...

The Double Helix Nebula is a gaseous nebula in the direction of the constellation Ophiuchus, near the center of our galaxy. It is thought to have been...

planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not...

directly toward the star that powers the Trifid nebula. This stalk is a prominent example of evaporating gaseous globules, or 'EGGs'. The stalk has survived...

Way galaxy. A star's life begins with the gravitational collapse of a gaseous nebula of material largely comprising hydrogen, helium, and trace heavier elements...

Huggins noted that the spectrum of Andromeda differed from that of a gaseous nebula. The spectrum of Andromeda displays a continuum of frequencies, superimposed...

planet during the formative period when Saturn was still surrounded by a gaseous nebula. This would explain the scarcity of rocky material within the rings...

A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives...

identified astronomical phenomenon. In contrast to the typical and well known gaseous nebulae within the plane of the Milky Way galaxy, IFNs lie beyond the main...

definition, if 2M1207b formed by direct gravitational collapse of a gaseous nebula, it would be a sub-brown dwarf rather than a planet. A similar debate...

to proceed to becoming a true planetary nebula, which is another astronomical object made up mostly of gaseous materials that was originally discovered...

Russian astronomer. He worked on stellar spectroscopy and the physics of gaseous nebulas. Together with Otto Struve, he studied the rapid rotation of stars...

the presolar nebula. The oldest inclusions found in meteorites, thought to trace the first solid material to form in the presolar nebula, are 4,568.2 million...

The Necklace Nebula (PN G054.2-03.4) is a 19-trillion-kilometre-wide (2.0 light-year-wide) planetary nebula located about 15,000 light-years away in the...
