Space #2 👩🚀 Flashcards
Why do astronauts wear space suits?
So they can look cool and breathe in space! Just kidding, they wear space suits to protect themselves from the extreme temperature, lack of air, and radiation in space.
How are space suits made?
(Not super important)
They are made with layers of strong fabrics and materials like Kevlar, nomex, and Gore-Tex, designed to withstand extreme conditions in space.
Can you go to the bathroom in a space suit?
Yes, if you don’t mind wearing it afterwards! Astronauts have special devices that allow them to pee in their space suits when they are on long space walks.
How do space suits keep astronauts safe from radiation?
With a big magnet! Just kidding, space suits have special materials like lead, which helps shield astronauts from dangerous radiation.
How long can an astronaut stay in a space suit?
Spacewalks usually last between five and eight hours, depending on the mission.
What is the purpose of space suits?
Space suits protect astronauts from extreme temperature, lack of air, and radiation in space.
What is a refracting telescope?
Answer: A refracting telescope is a type of telescope that uses lenses to bend and focus the light.
Explain why knowing when the summer solstice occurred was important for ancient peoples.
Knowing when the summer solstice occurred was important for ancient peoples because it marked the longest day of the year and the beginning of summer, which was significant for agriculture, trade, and religious celebrations.
Describe the difference between a geocentric model of the solar system and a heliocentric model.
A geocentric model means that Earth is at the center of the solar system, and everything else, like the Sun and planets, go around it. A heliocentric model means that the Sun is at the center of the solar system, and the planets, including Earth, go around it. So, basically, it’s either Earth or the Sun at the center.
What is a reflecting telescope?
Answer: A reflecting telescope is a type of telescope that uses mirrors to reflect and focus light.
Which form of electromagnetic radiation has the shortest wavelength?
Gamma Rays
Describe two advantages that a radio telescope has over an optical telescope.
Radio telescopes can be used day or night, they are much less affected by cloudy skies, and they open a new window to observe the Universe.
Describe the three steps in solar system formation.
The solar system formed in three steps. First, a cloud of gas and dust called a nebula collapsed. Second, the center of the nebula became the sun, while the rest flattened into a disk. Finally, clumps of dust and gas in the disk stuck together to form planets.
Besides distance from the Sun, give one difference between terrestrial planets and Jovian planets.
Terrestrial planets are small and rocky, while Jovian planets are large and made mostly of gas.
Explain the difference between a meteoroid, a meteor, and a meteorite.
A meteoroid is a small rock or debris in space. When it enters Earth’s atmosphere, it becomes a meteor, also called a shooting star. If it doesn’t burn up completely and lands on Earth, it becomes a meteorite.
What would happen to a rocket that does not reach Earth’s escape velocity of 28 000 km/h?
If a rocket does not reach the escape velocity of 28,000 km/h, it will not be able to break away from the Earth’s gravity and will fall back to the ground. It will not be able to reach outer space. Then it would blow up once it hits earth

What is the universe?
The universe is everything around us, including all the stars, planets, galaxies, and even empty space.
How old is the universe?
Scientists believe that the universe is about 13.8 billion years old.
What is a galaxy?
A galaxy is a huge group of stars, planets, gas, and dust that are held together by gravity.
What is dark matter?
Dark matter is a type of matter that we can’t see or detect directly, but we know it’s there because of its effects on other things in the universe.
What is inferred light?
Inferred light is a type of light that we can’t see with our eyes, but it can be detected by special cameras and sensors.
How is inferred light used in everyday life?
Inferred light is used in many things such as remote controls, security cameras, and even to detect heat loss in homes.
Can animals see inferred light?
Some animals like snakes and bats can see inferred light. They use this for hunting.
Why is inferred light important in astronomy?
Inferred light allows astronomers to see through dust clouds and observe objects that are too cold to emit visible light.
