    • C.

      Twirl

    • D.

      Spiral

    Correct Answer
    D. Spiral
    Explanation
    Spiral galaxies are characterized by their spiral arms that extend outwards from a central bulge. These arms are made up of young stars, gas, and dust, giving them a distinct appearance. Our galaxy, the Milky Way, is a spiral galaxy, as it also has a central bulge and spiral arms. Therefore, the correct answer is spiral.

    • A.

      An elliptical galaxy

    • B.

      An arm galaxy

    • C.

      A spiral galaxy

    • D.

      An irregular galaxy

    Correct Answer
    C. A spiral galaxy
    Explanation
    A spiral galaxy is the correct answer because it is characterized by its distinct arms and a central bulge. The arms of a spiral galaxy are long, curving structures that extend from the center, giving it a spiral-like appearance. These arms are formed by the concentration of stars, gas, and dust, and they often contain young, hot stars and star-forming regions. The central bulge of a spiral galaxy is a dense, spherical region at the center, composed of older stars. This combination of arms and a central bulge is unique to spiral galaxies.

      Irregular

    Correct Answer
    B. Elliptical
    Explanation
    Elliptical galaxies are the largest type of galaxies. They are characterized by their smooth and featureless appearance, lacking the spiral arms seen in spiral galaxies. These galaxies are primarily made up of older stars and have a more spherical or elliptical shape. They can range in size from relatively small to massive giant ellipticals that can contain trillions of stars. The absence of any other specific information in the question suggests that the correct answer is elliptical.

      An irregular galaxy

    Correct Answer
    C. An elliptical galaxy
    Explanation
    The given picture is of an elliptical galaxy. This can be determined by observing the shape of the galaxy in the picture. Elliptical galaxies are characterized by their smooth and elongated shape, resembling an ellipse. They lack the spiral arms seen in spiral galaxies and the irregular shape seen in irregular galaxies. Therefore, based on the shape of the galaxy in the picture, it can be concluded that it is an elliptical galaxy.

    • C.

      An elliptical galaxy

    • D.

      An irregular galaxy

    Correct Answer
    D. An irregular galaxy
    Explanation
    The given answer is "an irregular galaxy". This is because irregular galaxies do not have a defined shape or structure like spiral, elliptical, or lenticular galaxies. They are often chaotic in appearance, with no distinct spiral arms or central bulge. Irregular galaxies are typically smaller and contain a mix of young and old stars, as well as large amounts of gas and dust. Therefore, based on the description, the picture is most likely of an irregular galaxy.

    • C.

      A big bang

    • D.

      A small sun

    Correct Answer
    B. Giant black hole
    Explanation
    The correct answer is a giant black hole. This is because black holes are known to exist at the center of most, if not all, galaxies. They are extremely dense objects with a gravitational pull so strong that nothing, not even light, can escape from them. The presence of a giant black hole at the center of a galaxy helps explain the movement and behavior of stars and other celestial objects within the galaxy.

    ___________________ galaxies can form when two other galaxies collide.

    • A.

      An elliptical galaxy

    • B.

      An irregular galaxy

    • C.

      A collision galaxy

    • D.

      A spiral galaxy

    Correct Answer
    B. An irregular galaxy
    Explanation
    An irregular galaxy can form when two other galaxies collide. During the collision, the gravitational forces between the galaxies cause them to merge and disrupt their original structures, resulting in the formation of an irregular galaxy. Unlike elliptical or spiral galaxies, irregular galaxies do not have a defined shape or structure, and they often exhibit chaotic and disorganized patterns. Therefore, the correct answer is an irregular galaxy.

    The galaxy where few new stars are formed because of a lack of free gas is

    • A.

      An irregular galaxy

    • B.

      A spiral galaxy

    • C.

      A twirl galaxy

    • D.

      An elliptical galaxy

    Correct Answer
    D. An elliptical galaxy
    Explanation
    An elliptical galaxy is the correct answer because these galaxies are typically composed of older stars and have very little gas and dust. This lack of free gas makes it difficult for new stars to form, resulting in a low rate of star formation. In contrast, spiral galaxies have ongoing star formation due to the presence of gas and dust in their spiral arms. Irregular galaxies also have ongoing star formation, often due to interactions with other galaxies. There is no such thing as a "twirl galaxy," so that option can be ruled out.

      An irregular galaxy

    • D.

      An elliptical galaxy

    Correct Answer
    C. An irregular galaxy
    Explanation
    An irregular galaxy refers to a galaxy that does not have a defined shape. Unlike spiral or elliptical galaxies, which have more organized and symmetrical structures, irregular galaxies do not follow a specific pattern. They often have a chaotic appearance with no distinct arms or central bulge. Irregular galaxies are typically smaller and less massive compared to other types of galaxies. They can be the result of gravitational interactions with other galaxies or the remnants of galactic mergers.

    • A.

      Irregular galaxy

    • B.

      Ovular galaxy

    • C.

      Elliptical galaxy

    • D.

      Spiral galaxy

    Correct Answer
    C. Elliptical galaxy
    Explanation
    An elliptical galaxy is a type of galaxy that has an oval or egg-like shape. Unlike spiral galaxies, which have distinct arms, elliptical galaxies have a smooth and featureless appearance. They are composed mainly of older stars and contain very little gas and dust. The shape of an elliptical galaxy is due to its formation and evolution processes, such as mergers with other galaxies. Therefore, an elliptical galaxy is the correct answer for a galaxy that looks like an egg.

    • D.

      Very easy because of their color

    Correct Answer
    B. Very hard because they look like stars
    Explanation
    It is very hard to see a galaxy at night because they look like stars. Galaxies are vast collections of stars, gas, and dust, and from a distance, they appear as tiny points of light similar to individual stars. This similarity in appearance makes it difficult to distinguish galaxies from stars without the aid of telescopes or other astronomical tools.

    • D.

      The Earth

    Correct Answer
    C. A star
    Explanation
    The correct answer is a star. The center of our solar system is occupied by the Sun, which is a star. It is a massive ball of hot, glowing gases that emits light and heat, providing energy to the planets in our solar system. The Sun's gravitational pull keeps the planets in orbit around it, making it the central and most important celestial body in our solar system.

    Have we ever taken a picture of the whole Milky Way galaxy?

    • A.

      Yes

    • B.

      No, and probably not for a very long time

    • C.

      No, but we will in the near future

    Correct Answer
    B. No, and probably not for a very long time
    Explanation
    Taking a picture of the whole Milky Way galaxy is a challenging task due to its immense size and the limitations of current 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 our vantage point is not possible. Additionally, the vast distances and obstacles within the galaxy make it difficult to capture a complete picture. It is unlikely that we will be able to photograph the entire Milky Way galaxy in the near future, given the current technological limitations.
