Gravity pulls things toward bigger things, like the Sun or planets.

What shape is the Milky Way?

A spiral.

300

What are black holes?

Places in space with super strong gravity that even light can’t escape from.

300

Does size matter for gravity?

Yes! Bigger things have more gravity.

300

Where are stars born?


In the nebula, which is just a huge cloud of gas and dust.

300

What does “orbit” mean?

To go around something, like the Earth orbits the Sun.

300

What are the 3 types of galaxies?

Spiral, Elliptical, Irregular

400

How do rockets move in space?

Rockets push gas out one way to go the opposite way (like a balloon flying when you let go).

400

What causes craters on the Moon?

Space rocks hitting the Moon

400

What’s the life cycle of a star?

Stars are born, live for a long time, and can become white dwarfs or supernovas when they die.

400

Do all planets orbit the Sun at the same speed?

No, the closer planets go faster, and the farther ones go slower.

400

What are galaxies made of?

Stars, dust, gas, black holes and planets.

500

Can we see all of space? If no, why not?

No, only a tiny part because it’s so huge!

500

 What do star colors mean? (Hint: blue, white, yellow, red) You have to get all of them correct to get the points.

  • Blue = Hottest

  • White = Very Hot

  • Yellow = Hot (like our Sun!)

  • Red = Cooler

500

What are the phases of the moon?

new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent

500

Why can’t we see the whole galaxy?

Because we live inside it and can only see nearby stars.
