Accepted Answer

Water is important because all living things on Earth need it to survive. Scientists think that life elsewhere might also need water to live.

Question 8

How many exoplanets have been found?

Accepted Answer

Thousands of exoplanets have been found so far! And scientists are finding more all the time.

Accepted Answer

The Kepler Space Telescope is a spacecraft used to look for exoplanets. It helped find many of the exoplanets we know about today.

Question 13

Is there another Earth out there?

Accepted Answer

Scientists are looking for planets that are similar to Earth, but they haven't found one exactly like ours yet. However, they have found some that are close!

A telescope is a tool that makes things that are far away look closer. It's like super powerful binoculars for looking at stars and planets.

Question 15

What is the James Webb Space Telescope?

Accepted Answer

The James Webb Space Telescope is a big telescope in space that helps us see even more distant things. It's designed to learn more about stars, galaxies, and possibly exoplanets.

Question 16

Can exoplanets be different sizes?

Accepted Answer

Yes, exoplanets can be big, like Jupiter, or small, like Earth. They come in all sorts of sizes, some even bigger than our biggest planets.

Question 17

What are alien life forms?

Accepted Answer

Alien life forms are living things that might exist on other planets. They could be very different from what we know on Earth, maybe even in ways we can’t imagine!

Question 18

Are there other solar systems?

Accepted Answer

Yes, there are many other solar systems out there. Each one has a star, and some have planets that orbit them, just like ours.

Question 19

Why can't we see exoplanets directly?

Accepted Answer

Exoplanets are very far away, and they're often hidden by the bright light of their stars. It’s like trying to see a tiny dot next to a bright light bulb from across a room.

Question 20

What makes earth special for life?

Accepted Answer

Earth has water, air, and the right temperature, which are just right for life. Scientists look for similar conditions on other planets to see if life could be there too.
