Not exact matches

More accurate distances between the most common type of «planetary nebulae» and the Earth can be estimated simply with three sets of data: firstly, the size of the object on the sky taken from the latest high resolution surveys; secondly, an accurate measurement of how bright the object is in the red hydrogen - alpha emission line; and thirdly, an estimate of the dimming toward the nebula caused by so called interstellar - reddening.

That phase is called the proto - planetary nebula, and is so short that only a few of these objects are known.

As well as this black hole, Messier 15 is known to house a planetary nebula, Pease 1 [4]-- and it was the first globular known to contain one of these objects [5].

The model we propose can help explain the presence of bipolar planetary nebulae, the presence of knotty jet - like structures in many of these objects, and even multipolar planetary nebulae.

The final stages of life for a star like our Sun result in the star blowing its outer layers out into the surrounding space, forming objects known as planetary nebulae in a wide range of beautiful and striking shapes.

Planetary Nebula Messier 76 (M76, NGC 650/651) is one of the faintest Messier Objects, and one of only four planetary nebulae in Messier's catalog, situated in the Eastern part of constellationPlanetary Nebula Messier 76 (M76, NGC 650/651) is one of the faintest Messier Objects, and one of only four planetary nebulae in Messier's catalog, situated in the Eastern part of constellationplanetary nebulae in Messier's catalog, situated in the Eastern part of constellation Perseus.

The first of these are planetary nebulae, so called because they're round objects that resemble planets.

Construct whole planetary systems, nebulae, galaxies or fictional objects.

The name «planetary nebula» refers only to the round shape that many of these objects show when examined through a small telescope.

An analysis of the data indicated the presence of 10 times the amount of brown dwarfs and very - low - mass planetary objects than would be expected in line with current theories on star formation in the nebula.

This planetary nebula is certainly the most impressive object of its kind in the sky, as the angular diameter of the luminous body is nearly 6 arc minutes, with a faint halo extensing out to over 15», half the apparent diameter of the Moon (Millikan 1974).

Occasionally these objects look something like planetary nebulae, as in the case of the Crab Nebula, but they differ from the latter in three ways: (1) the total mass of their gas (they involve a larger mass, essentially all the mass of the exploding star), (2) their kinematics (they are expanding with higher velocities), and (3) their lifetimes (they last for a shorter time as visible nebulae).

This allows it to study a variety of astronomical objects, such as the molecular gas in planetary nebulae, molecules on active comets, the heating mechanisms of red giants and the afterglows of gamma - ray bursts.

On about the western edge of M24, 12th - magnitude planetary nebula NGC 6567, of about 8 arc minutes diameter, can be found, a foreground object at a distance of about 4,000 light - years.
