We are a Goldie Loc's Planet 2 - we got the right of land to water ratio 3 - the moon is at the right size and orbit to prevent the earth from wobbling 4 - the gas giants in our solar system do a great job at cleaning up roaming ice and rock that is flying around our solar system 5 - right distance from the galactic core.

Earlier studies had suggested that the gravity of nearby stars would have ripped apart these primordial clumps, but the new simulations show that this would only happen in the crowded core of galaxies, leaving the clumps in the galactic suburbs intact (arxiv.org/abs/1006.3392).

Perhaps it is through the spiraling collision of stars or star - size black holes in the overcrowded galactic core.

The leading suspects in the half - century old mystery of the origin of the highest - energy cosmic particles in the universe were in galaxies called «active galactic nuclei,» which have a super-radiating core region around the central supermassive black hole.

He is a specialist on active galactic nuclei, superbright galactic cores thought to be caused by giant black holes sucking in and heating up quantities of gas and dust.

Perhaps it is through the spiraling collision of starsor star - size black holes in the overcrowded galactic core.

The observations validate recent simulations by research groups at Princeton, Oxford, and Rutgers universities, which suggest that as the Milky Way's spiral arms and galactic bar travel in space, they can gravitationally deflect stars into streams that run inward or outward from the galactic core, like spokes in a wheel.

Hooper and colleague Tracy Slatyer at the Institute for Advanced Study in Princeton, New Jersey, have found the signal far enough away from the galactic core to make it unlikely that it is being produced solely by the Milky Way's central hubbub (arxiv.org/abs/1302.6589).

That material may fall in a concentrated stream toward the galactic core — and it could ignite a quasar.

RX J1140.1 +0307 is such a galaxy — in fact, it is centered on one of the lowest black hole masses known in any luminous galactic core.

A lack of stars close to the galactic center distinguishes massive galaxies from standard elliptical galaxies, which are much brighter in their cores.

Those gravity waves came from two black holes more massive than any known outside a galactic core and formed in an environment different than the Milky Way.

Astronomers have yet to find one of these, but it should be possible to see up to 10 per year thanks to a new generation of telescopes capable of spotting small changes in bright galactic cores.

Such isolated black holes would be too dim to discern at the galactic core, but the x-ray binaries serve as a tracer suggesting they're there — and in really big numbers.

The halo originates from galactic «fountains» caused by star formation in the disk and a super-wind coming from the galaxy's core.

Such stars tend to have larger apparent motions, with rapid passages in highly inclined and elliptical orbits around the galactic core.

Furthermore, the global intrinsic oscillations provide a means to discern red - giant stars in the pre-helium core burning from the ones in the helium core burning phase and provide an estimate of stellar ages, a key ingredient for galactic studies.

In addition, tidal forces affecting the Oort Cloud come from the differential gravitational forces exerted by stars in the Milky Way's galactic disk and by the galactic core on the Sun and comets as a result of their relative location in the Solar System, which have been modelled with numerical simulations (Duncan et al, 1987In addition, tidal forces affecting the Oort Cloud come from the differential gravitational forces exerted by stars in the Milky Way's galactic disk and by the galactic core on the Sun and comets as a result of their relative location in the Solar System, which have been modelled with numerical simulations (Duncan et al, 1987in the Milky Way's galactic disk and by the galactic core on the Sun and comets as a result of their relative location in the Solar System, which have been modelled with numerical simulations (Duncan et al, 1987in the Solar System, which have been modelled with numerical simulations (Duncan et al, 1987).

NASA (Shock rings around Supernova 1987A)-- larger image While primordial supernovas created much of the heavier elements such as iron found in the Solar System, Sol orbits the galactic core without frequent crossings of the spiral arms where life - threatening supernovas are more common.

Astronomer Vera Cooper Rubin found over decades of radio observations that the rotational velocity of clouds of ionized hydrogen (HII regions) in spiral galaxies like the Milky Way was not decreasing at increasing distance from their galactic cores, like the velocity of the planets around the Sun.

This two light - year square image of the innermost region of the galactic core depicts hot stars in blue and cool stars in red, and two arrows pointing towards Sgr A * and S2 (more at ESO and Astronomy Picture of the Day).

Past computer modelling have shown that galactic bars and rings can be formed by gravitational interactions, and such structures in the Milky Way's core even may be related to interactions with our largest neighbor, the Andromeda Galaxy.

This region contains relatively young to intermediate - aged stars that within around five billion years old with relatively higher average metallicity than other galactic regions located outside of the galactic core, in a circular band that broadens with time.

Of course, «the system» refers to everything you have included in it but, if we idealize it as our local solar system orbiting the galactic core (and neglecting other mass in the galaxy), then the barycenter orbits the galactic core and the constituents of the solar system orbit the barycenter.

Astronomers say they found a dozen black holes in the center of the Milky Way and that thousands of others are likely at our galactic core.
