Sa galaxies have large nuclear bulges and tightly wound spiral arms, while Sc galaxies have small bulges and loosely wound arms. Barred spiral: Obvious disk shape with elongated, bright centers and well-defined spiral arms. SBa galaxies have large nuclear bulges and tightly wound spiral arms, ...

This structure of galaxies consists of rich and poor clusters, connected by filaments and sheets, with regions largely devoid of galaxies (voids) in between 1 . Numerical simulations of the growth of initial density fluctuations through a nonlinear regime, motivated by the likely physics of the ...
How many galaxies are there in the universe? How can the universe be both infinite but expanding? How do you think the Universe is going to end? What is the Universe - space or matter? How many dimensions are needed to describe the universe? How did the mass of the universe come into...
- Objects high in the sky will look better, as there is less atmosphere in the path (technical term: "air mass"). Choose bright galaxies that are high in the sky if possible. Of course some of the brightest ones might not be so high up and still be great targets. ...
The distribution of galaxies in the universe is not arbitrary, they are arranged in groups of clusters that are bounded by gravitation. These clusters...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
8 years old doesn't give you much to work with in the realm of observing galaxies unless you're fortunate enough to live out in the middle of nowhere -- where the Milky Way is an obvious naked eye sight, and where there are no outdoor lights of any kind within sight and no bright...
One solar mass is defined as the mass of our sun. Supersized black holes This is the universe’s way of supersizing. NASA produced a clip showing the relative sizes of the sun, planets and 10 supermassive black holes. Supermassive black holes reside in the center of most large galaxies, ...
LARGE-SCALE structure in the distribution of galaxies is thought to have evolved through gravitational instabilities from small density fluctuations in the (largely homogeneous) early Universe. This structure of galaxies consists of rich and poor cluster
Though quite a bit worse for wear, the LMC still retains a compact, stubby halo of gas – something that it wouldn’t have been able to hold onto gravitationally had it been less massive. The LMC is 10 percent the mass of the Milky Way, making it heftier than most dwarf galaxies. ...
