What is a white dwarf?
-
A small guy with a long white beard
-
The remains of a burnt out star
Correct Answer
A. The remains of a burnt out starExplanation
A white dwarf is the remains of a burnt out star. After a star exhausts its nuclear fuel, it undergoes a supernova explosion, shedding its outer layers and leaving behind a dense core. This core, composed mostly of carbon and oxygen, collapses under its own gravity and becomes a white dwarf. White dwarfs are incredibly dense, with a mass comparable to that of the Sun but compressed into a size similar to Earth. They are extremely hot and emit a faint white glow, hence the name "white dwarf."Rate this question:

Which planet is hotter?
-
Mercury
-
Venus
Correct Answer
A. VenusExplanation
Venus is hotter than Mercury. This is because Venus has a thick atmosphere composed mainly of carbon dioxide, which creates a greenhouse effect. The greenhouse effect traps heat from the Sun, causing Venus to have a surface temperature of about 900 degrees Fahrenheit (475 degrees Celsius). On the other hand, Mercury has a thin atmosphere and is much closer to the Sun, but its lack of atmosphere means that it cannot retain heat as effectively. Therefore, Venus is the hotter planet.Rate this question:

We are made out of the stuff that stars are made out of.
-
True
-
False
Correct Answer
A. TrueExplanation
This statement is true because the elements that make up our bodies, such as carbon, oxygen, and nitrogen, were formed in the cores of stars through nuclear fusion. These elements were then released into the universe when the stars exploded in supernovae. Over time, these elements came together to form planets, including Earth, and eventually life as we know it. Therefore, we can say that we are indeed made out of the same stuff that stars are made out of.Rate this question:

What use are the constellations?
-
Navigation
-
Landmarks to other constellations
-
All of the above
-
I don't know
Correct Answer(s)
A. Navigation
A. Landmarks to other constellations
A. All of the aboveExplanation
Constellations are useful for navigation purposes because they provide a reference point for sailors, pilots, and explorers to determine their position and direction. They act as celestial landmarks, helping to guide people across the Earth's surface or through the vastness of space. Additionally, constellations can serve as landmarks to locate other constellations, aiding in celestial navigation. Therefore, the correct answer is that constellations are used for navigation, as landmarks to other constellations, and for all of the above purposes.Rate this question:

How fast does light travel?
-
30,000 km each second
-
327,896 km each second
-
299,792 km each second
-
Infinite speed
Correct Answer
A. 299,792 km each secondExplanation
Light travels at a speed of 299,792 km each second. This is the correct answer because it is a well-established scientific fact that light travels at a constant speed in a vacuum. This speed, often referred to as the speed of light, is a fundamental constant in physics and has been measured and confirmed through various experiments. It is important to note that the speed of light may vary when passing through different mediums, but in a vacuum, it travels at approximately 299,792 km per second.Rate this question:
