Write. Hubble's constant is.
True.
Terms in this set (24) Compared to the spirals, elliptical galaxies tend to be more dusty.
False.
The two galaxies are: Large Magellanic Cloud (LMC), approximately 163,000 light-years away Our Milky Way Galaxy is one of three large galaxies in the Local Group of Galaxies. The Magellanic Clouds (or Nubeculae Magellani) are two irregular dwarf galaxies visible in the Southern Celestial Hemisphere; they are members of the Local Group and are orbiting the Milky Way galaxy.Because both show signs of a bar structure, they are often reclassified as Magellanic spiral galaxies.
Once in every couple hundred years, and we are overdue. courtney_crick.

Satellites of the Milky Way In the southern hemisphere of the Earth, one can look up at the sky and see …
What two quantities did Edwin Hubble compare for a sample of galaxies to discover the expansion of the Universe? The Local Group is the galaxy group that includes the Milky Way. Which property is common to spiral galaxies?
False 24) M31 in Andromeda is a bigger version of our Galaxy, and the largest member of the Local Group. There are more giant elliptical than dwarf galaxies. Unlike spirals, elliptical galaxies do not contain a flattened disk. Astronomy Chapter 15. Gravity Electromagnetic Weak Strong. What type of galaxy can look like one huge star but is really a group of tightly packed stars?
Roughly how many galaxies make up our Local Group?
One of the largest known spiral galaxies is NGC 6872, which is 522,000 light-years across from the tips of its outstretched spiral arms — that's about 5 times the size of the Milky Way. No, because galaxies in the Local Group are gravitationally bound together. The Local Group is about 3 million light years across with the two large spirals, the Milky Way and Andromeda Galaxy, dominating the two ends.
Andromeda . Compared to spiral galaxies elliptical galaxies have. stellar parallax. A spiral galaxy that is called an Sa galaxy has... a central bulge that is very spread out.

Learn. about 60 or so millions thousands only three many hundreds Which of the following is not true about the Local Group of galaxies (of which the Milky Way is a member)?

The four forces are. Learn. The Local Group has much more than 10 galaxies, though. alexia_carolyn. False.
The Local Group includes the galaxies of our "immediate neighborhood" (a few million light-years distance at most!). Flashcards. All of these motions, although not felt by us on Earth, are observed by watching the sky and prove that we are not "just sitting here." Irregulars typically have very few blue stars. PLAY.
