Urantia Book 15:3. The Superuniverse of Orvonton

15:3.1 Practically all of the starry realms visible to the naked eye on Urantia belong to the seventh section of the grand universe, the SuperUniverse of Orvonton. The vast Milky Way starry system represents the central nucleus of Orvonton, being largely beyond the borders of your local universe. This great aggregation of suns, dark islands of space, double stars, globular clusters, star clouds, spiral and other nebulae, together with myriads of individual planets, forms a watchlike, elongated-circular grouping of about one seventh of the inhabited evolutionary universes.

What Is a Satellite Galaxy?

Our sun is part of a massive collection of stars in the Milky Way galaxy. These hundreds of billions of stars orbit the galaxy’s center. But did you know that there are things that are even bigger orbiting the Milky Way’s center? Other galaxies orbit it too!

These less massive galaxies have their own impressive collection of stars, which all orbit their own center; but the galaxies and everything in them orbit our galaxy too. It’s as if our galaxy is the sun and those other galaxies are planets. Astronomers call them “satellite galaxies.”

The Nearest Galaxies

The Large and Small Magellanic clouds were thought to be the closest galaxies to ours, until 1994, when the Sagittarius Dwarf Elliptical Galaxy (SagDEG) was discovered. In 2003, the Canis Major Dwarf Galaxy was discovered - this is now the closest known galaxy to ours! …

The Canis Major Dwarf Galaxy

The Canis Major Dwarf Galaxy is only 25,000 light years from the Sun, and 42,000 light years from the Galactic center. It too, is well-hidden by the dust in the plane of the Milky Way - which is why it wasn't discovered until recently.

This galaxy is also being pulled apart by the Milky Way's gravity - as it orbits the Milky Way, it is leaving a long filament of stars, gas, and dust in its wake. This 200,000 light year-long filament is known as the Monoceros Ring, and actually wraps three times around our galaxy! The Canis Major Dwarf galaxy was discovered in the course of the investigation of this Ring, which was first discovered in 2002.

Distance Information

The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.

The Large Magellanic Cloud, 1,690,000,000,000,000,000 km (179,000 light years) away, was once considered the nearest galaxy outside of the Milky Way. The Small Magellanic Cloud is 1,980,000,000,000,000,000 km (210,000 light years) away.
How Do We Calculate Distances of This Magnitude?

Astronomers primarily use Cepheid and/or RR Lyrae Variables to measure distances to the LMC, the SMC, and the Dwarf Galaxies. The distance to the LMC has come to play such a crucial role in establishing the extragalactic distance scale that several research groups are applying a variety of methods other than the Cepheids and RR Lyraes. These alternative techniques, which include the use of SN 1987A, the so-called red clump stars, and eclipsing binaries are used to check the accuracy of the period-luminosity relationships. By using several different methods to determine distances, astronomers can increase the accuracy of and our confidence in the RR Lyrae and Cepheid methods, and the distances determined by them.

For more information about Cepheids and RR Lyrae, please read the section on calculating distances in the Milky Way.
Why Are These Distances Important To Astronomers?

If you measure the distance to one object in the LMC, for example, you know the distances to all the millions of objects in the LMC fairly accurately. Of course, there are not all exactly the same, but the thickness of LMC, as seen from the Earth, is much smaller than the typical uncertainties in the distances to individual objects in the Milky Way. Astronomers therefore often study LMC objects then calculate their true brightness from their apparent brightness and the latest (the most accurate) distance to the LMC. For example, astronomers have studied the supernova remnants to compare with theoretical models, or to derive a relationship between their size, energy, and brightness.
Travel Time

To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager's speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!

Urantia Book 15:3. The Superuniverse of Orvonton

15:3.2 From the astronomical position of Urantia, as you look through the cross section of near-by systems to the great Milky Way, you observe that the spheres of Orvonton are traveling in a vast elongated plane, the breadth being far greater than the thickness and the length far greater than the breadth.

15:3.3 Observation of the so-called Milky Way discloses the comparative increase in Orvonton stellar density when the heavens are viewed in one direction, while on either side the density diminishes; the number of stars and other spheres decreases away from the chief plane of our material superuniverse. When the angle of observation is propitious, gazing through the main body of this realm of maximum density, you are looking toward the residential universe and the center of all things.

15:3.4 Of the ten major divisions of Orvonton, eight have been roughly identified by Urantian astronomers. The other two are difficult of separate recognition because you are obliged to view these phenomena from the inside…

15:3.5 The rotational center of your minor sector is situated far away in the enormous and dense star cloud of Sagittarius, around which your local universe and its associated creations all move, and from opposite sides of the vast Sagittarius subgalactic system you may observe two great streams of star clouds emerging in stupendous stellar coils.

15:3.6 The nucleus of the physical Local System to which your sun and its associated planets belong is the center of the onetime Andronover Nebula. This former spiral nebula was slightly distorted by the gravity disruptions associated with the events which were attendant upon the birth of your Solar System, and which were occasioned by the near approach of a large neighboring nebula. This near collision changed Andronover into a somewhat globular aggregation but did not wholly destroy the two-way procession of the suns and their associated physical groups. Your solar system now occupies a fairly central position in one of the arms of this distorted spiral, situated about halfway from the center out towards the edge of the star stream.

15:3.7 The Sagittarius sector and all other sectors and divisions of Orvonton are in rotation around Uversa, and some of the confusion of Urantian star observers arises out of the illusions and relative distortions produced by the following multiple revolutionary movements:

1. The revolution of Urantia around its sun.

2. The circuit of your Solar System about the nucleus of the former Andronover nebula.

3. The rotation of the Andronover stellar family and the associated clusters about the composite rotation-gravity center of the star cloud of Nebadon.

4. The swing of the local star cloud of Nebadon and its associated creations around the Sagittarius center of their minor sector.

5. The rotation of the one hundred minor sectors, including Sagittarius, about their major sector.

6. The whirl of the ten major sectors, the so-called star drifts, about the Uversa headquarters of Orvonton.

7. The movement of Orvonton and six associated superuniverses around Paradise and Havona, the counterclockwise processional of the superuniverse space level.

15:3.15 These multiple motions are of several orders: The space paths of your planet and your solar system are…inherent in origin. The absolute counterclockwise motion of Orvonton is also…inherent in the architectural plans of the master universe. But the intervening motions are of composite origin, being derived in part from the constitutive segmentation of matter-energy into the superuniverses and in part produced by the intelligent and purposeful action of the Paradise Master Force Organizers.
