A typical galaxy contains hundreds of billions of stars.
A typical galaxy may contain a hundred billion stars like our Sun Geodesic.
The odds of a stellar tidal disruption in a typical galaxy are low, about one in 10,000 annually.
Using a technique akin to overlaying thousands of faint X-ray images to create one sharp picture, astronomers have discovered that typical galaxies may be twice as large and contain twice as much mass as suggested by previous measurements.
By comparison, the glittering disk of stars in a typical galaxy like the Milky Way, where Earth is located, stretches only about 50,000 light-years from center to edge and contains about 100 billion stars.
For comparison, the diameter of a typical galaxy is 30,000 light-years, and the typical distance between two neighboring galaxies is 3 million light-years.
It's somewhat comforting to hear astronomers estimate that a black hole's consumption of a star occurs only once every 10,000 years in a typical galaxy.
Given the size, calculations indicate that the water vapor is dense when compared to many other astronomical vapors-it is about one to two orders of magnitude denser and about 5 times hotter than water vapor found in a typical galaxy.
A typical galaxy contains billions of stars but looks "smooth" when viewed through a telescope, because the stars are blurred together.
A typical galaxy contains hundreds of billions of stars, and there are more than 100 billion (10) galaxies in the observable universe.
