What is a comet?

• large objects made of dust and ice that orbit the Sun. Best known for their long, streaming tails, these ancient objects are leftovers from the formation of the solar system 4.6 billion years ago.

• an area of such immense gravity that nothing -- not even light -- can escape from it.

• Planets that orbit around other stars

• the biggest explosion that humans have ever seen.

What is a black hole?

• when one object crosses in front of another in space

• an area of such immense gravity that nothing -- not even light -- can escape from it.

• a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity.

• how astronomers explain the way the universe began.

What is the mission of the James Webb telescope?

• The first person who discovered the stars

• an infrared observatory in space to help the discoveries of the Hubble Space Telescope.

• a planet that is far away from space

What is a solar flare?

• huge bubbles of radiation and particles from the Sun.

• sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots.

• areas that appear dark on the surface of the Sun.

• space weather can affect Earth and the rest of the solar system.

How Earth rotates?

• Earth rotates on its own axis around every 24 hours and around the Sun every year

• Earth rotates on its own axis around the milky way every 24 hours and around Jupiter every year

• Earth rotates on its own axis around every year and around a blackhole every 24 hours

How was the universe created? 

• the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

• the distance light travels in one Earth year.

• how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now

• area of such immense gravity that nothing -- not even light -- can escape from it.

Who is in charge to study the universe?

• Astronomers

• Teachers

• Kids

• The president
