What would the night sky look like on the edge of the galaxy?
There aren’t many stars out there, so the night sky away from the galactic disk would be fairly dark. Toward the galaxy you you have an edge on view of the galactic disk. As for a sky full of galaxies, you might see a few but probably not.
What would the night sky look like in the center of the Milky Way?
If you lived in the center of the Milky Way, you would look up at a sky thick with stars, up to 1 million times denser than we’re used to seeing. The closest star to our sun is about four light-years away; in the center of the galaxy, stars are only 0.4–0.04 light-years apart.
What is at the edge of the Milky Way galaxy?
Looking at the dwarf galaxies around the Milky Way, Deason concluded that the edge of the Milky Way’s dark matter lies almost one million light-years from the centre of the Galaxy. The Andromeda Galaxy is about two million light-years from the Milky Way, and observations suggest that its mass is comparable to our own.
What are the terrestrial planets?
The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.
When we look into the band of light in our sky?
When we look into the band of light in our sky that we call the Milky Way, can we see distant galaxies? Why or why not? No, because the stars, gas, and dust of the Milky Way block us from seeing them.
Is there a black hole at the center of every galaxy?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas. This chart shows the relative masses of super-dense cosmic objects.
What universe do we live in?
the Milky Way
Our home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
What would Earth look like if the Sun was a red dwarf?
The goldilocks zone around a red dwarf is much closer and here on Earth we would likely freeze. Trying to live around this new red dwarf star would also mean that we had more intense magnetic fields and violent solar flares to deal with. Red dwarfs stars are smaller and cooler than our relatively average star, the Sun.
