Light and Color in the Universe Quiz - Vox

What is the primary function of the Hubble Space Telescope?

• To search for signs of extraterrestrial life

• To study the behavior of comets

• To capture images of black holes

• To measure the brightness of light reflecting off objects in space

What is the guiding principle in colorizing black and white images?

• Applying random colors to the image

• Using only the primary colors of light

• Converting the image to grayscale

• Combining red, green, and blue in different proportions

What is the main reason for using narrowband filtering in Hubble's images?

• To study the behavior of black holes

• To create visually appealing images

• To track the presence of specific elements in the universe

• To capture images of distant galaxies

What is the purpose of assigning different elements to red, green, and blue in narrowband filtering?

• To visually separate the elements and create a full color image

• To highlight the similarities between the elements

• To produce a true color image of the elements

• To create a grayscale representation of the elements

What is the main advantage of recording light outside of the visible spectrum using the Hubble Space Telescope?

• To reveal information about objects that are not visible in visible light

• To search for signs of intelligent life in the universe

• To capture images of planets in our solar system

• To study the behavior of asteroids

What is the purpose of using computer programs like Photoshop in adding color to Hubble's images?

• To create true color images based on filtered exposures

• To enhance the brightness of the images

• To convert the images to grayscale

• To add random colors for aesthetic appeal

What is the visible spectrum and how is it perceived by the human eye?

• It is the range of radio frequencies that are detectable by human-made devices

• It is the range of sound frequencies that are audible to the human ear

• It is the range of light frequencies that are invisible to the human eye

• It is the range of light frequencies that are visible to the human eye

What is the primary reason for using filters for specific colors of light in early color photography?

• To create a monochromatic image

• To enhance the contrast of the image

• To add artistic effects to the image

• To capture different color components of the image separately

What is the purpose of mapping out how different gases interact in the universe using color?

• To study the behavior of black holes

• To create visually appealing images of galaxies and nebulae

• To visualize the chemical makeup of an object or an area in space

• To search for signs of extraterrestrial life

What is the significance of using color to track the presence of specific elements in Hubble's images?

• It allows for the detection of alien civilizations in the universe

• It provides critical information about how stars and galaxies form over time

• It creates beautiful images for public viewing

• It helps in identifying potential locations for future space missions
