What type of galaxy is this?
Explanation
Make sure that you have spelled it correctlyRate this question:
- 3.
IF you look outside at night to see a galaxy it is
-
Very easy because of their shape
-
Very hard because they look like stars
-
Very hard because they are invisible
-
Very easy because of their color
Correct Answer
A. Very hard because they look like starsExplanation
It is very hard to see a galaxy at night because they look like stars. Galaxies are massive systems of stars, gas, and dust, and from a distance, they appear as faint, hazy patches of light that can easily be mistaken for individual stars. Since galaxies are incredibly far away from Earth, their light is spread out and diluted, making them difficult to distinguish from the countless other stars in the night sky. Therefore, it is challenging to identify and observe galaxies amidst the vast number of stars visible at night.Rate this question:

Correct Answer
A. Elliptical galaxyExplanation
An elliptical galaxy is a type of galaxy that has an oval or egg-like shape. Unlike spiral galaxies, which have distinct arms, or irregular galaxies, which lack a defined shape, elliptical galaxies have a smooth and symmetrical appearance. They are often described as being round or elongated, resembling the shape of an egg. This is why a galaxy that looks like an egg is called an elliptical galaxy.Rate this question:

-
An irregular galaxy
-
An elliptical galaxy
Correct Answer
A. An irregular galaxyExplanation
An irregular galaxy is a type of galaxy that does not have a defined shape. Unlike spiral or elliptical galaxies, irregular galaxies lack the organized structure and symmetry typically seen in other types of galaxies. They often appear chaotic and disordered, with no distinct spiral arms or elliptical shape. Irregular galaxies can vary greatly in size and can contain a mix of young and old stars. They are thought to have been formed through interactions with other galaxies or through disruptions caused by gravitational forces.Rate this question:

What galaxy has arms and a center bulge?
-
An elliptical galaxy
-
An arm galaxy
-
A barred spiral galaxy
-
An irregular galaxy
Correct Answer
A. A barred spiral galaxyExplanation
A barred spiral galaxy is the correct answer because it is a type of galaxy that has distinct arms and a central bulge. Unlike a regular spiral galaxy, a barred spiral galaxy has a bar-like structure that extends through its center, connecting the arms. This bar is formed by dense concentrations of stars and can be seen as a straight or curved feature. The arms of a barred spiral galaxy spiral out from the ends of the bar, giving it a unique appearance.Rate this question:

Our galaxy's shape is called a _________________ galaxy
-
Irregular
-
Elliptical
-
Twirl
-
Spiral
Correct Answer
A. SpiralExplanation
The correct answer is spiral because our galaxy, the Milky Way, is classified as a spiral galaxy. Spiral galaxies have a distinct spiral structure, with arms that extend outwards from a central bulge. These arms are formed by the concentration of stars, gas, and dust. The spiral shape is a result of the rotation of the galaxy.Rate this question:

Correct Answer
A. Solar system. galaxy, universeExplanation
The correct order of the objects from smallest to largest is solar system, galaxy, universe. The solar system refers to the sun and all the objects that orbit around it, such as planets, moons, asteroids, and comets. A galaxy is a large system of stars, gas, and dust held together by gravity, with billions of stars and other celestial bodies. The universe is the entirety of space, time, matter, and energy, including all galaxies and other forms of matter and energy. Therefore, the solar system is the smallest, followed by the galaxy, and then the universe.Rate this question:

Have we ever taken a picture of the whole Milky Way galaxy?
-
Yes
-
No, and probably not for a very long time
-
No, but we will in the near future
Correct Answer
A. No, and probably not for a very long timeExplanation
Taking a picture of the whole Milky Way galaxy is currently not possible due to its immense size and our limited technology. The Milky Way is a spiral galaxy with a diameter of about 100,000 light-years, and we are located within it. Therefore, capturing an image of the entire galaxy from an external perspective is challenging. Additionally, the vast distances and the presence of interstellar dust further hinder our ability to obtain a complete picture. It would require significant advancements in technology and space exploration to capture an image of the entire Milky Way, which is unlikely to happen in the near future.Rate this question:
