What Is a Planet?
A planet is a big, round object that orbits (or moves around) a star. Earth is a planet that orbits the Sun. There are other planets in our solar system, like Mars, Jupiter, and Saturn. Scientists have also found thousands of planets outside our solar system. These are called exoplanets!
Hello my friends!
For a quick note, welcome to Tidbits with Titus, a podcast and newsletter where we tackle the big, curious questions kids ask every day in fun, bite-sized ways! I’m Alexander Titus, but I go by Titus. I’m a scientist, adventurer, and a huge fan of making science, technology, and life accessible to all ages. From “How does electricity work?” to “What are taxes?” and even “Why is the sky blue?” I’m here to dive into these wonder-filled questions with engaging stories and simple explanations that spark curiosity and make learning a joy. This effort is all about creating a space where families can learn together, discover the magic of the every day, and find thoughtful ways to explore the world’s big mysteries. Let’s make curiosity a family tradition—one tidbit at a time!
Just so you know, these podcast episodes are all AI-generated using Google’s really cool NotebookLM technology. That means there are some errors in how words are said, but that is part of the fun!
If your little ones have questions that you want help answering, shoot me an email at questions@tidbitswithtitus.com and I’ll see what I can do!
You can subscribe to the newsletter that has this information as well at tidbitswithtitus.com.
Also please share with anyone you think would be interested. The more the merrier!
Cheers,

What Do Living Things Need?
To understand if life can exist on other planets, we need to think about what life needs to survive. Here on Earth, living things need:
Water – All animals and plants need water to live.
Air – We breathe oxygen to stay alive.
Food – Animals eat food to get energy.
The Right Temperature – If it’s too hot or too cold, it’s hard for living things to survive.
Scientists look for planets that might have these things to see if life could exist there.
Mars: Our Closest Neighbor
Mars is one of the most interesting planets when it comes to searching for life. It is cold and dry, but scientists have found signs that water used to flow there a long time ago. Some tiny creatures, like bacteria, can live in very cold or very dry places on Earth. So, could tiny life forms be hiding on Mars? Scientists are sending robots, like the Perseverance rover, to look for clues!
The Search for Life in Space
Scientists use special telescopes to search for planets that might have life. They also send space probes (machines that explore space) to study planets and moons up close. Here are some exciting places they are looking:
Europa – This is one of Jupiter’s moons. It has a thick layer of ice, and scientists think there might be a huge ocean underneath! If there’s water, there could be life.
Enceladus – A moon of Saturn that also has ice and water. Some scientists think it might have the right conditions for tiny life forms.
Exoplanets – Scientists have found planets far away that might have the right conditions for life. Some of them are in the "habitable zone," meaning they are just the right distance from their star for water to exist.
What Would Aliens Look Like?
If there is life on other planets, would it look like us? Maybe, but it could also look very different! Some aliens might be tiny, like bacteria. Others might have big eyes to see in the dark or thick skin to survive harsh weather. Scientists don’t know what aliens would look like, but it’s fun to imagine!
How Do Scientists Listen for Aliens?
Did you know that scientists use giant radio telescopes to listen for signals from space? They hope to hear a message from intelligent life. So far, they haven’t found anything, but space is very big. Maybe one day, we will hear something!
Could We Live on Another Planet?
Scientists are also looking for planets where humans could live one day. If Earth ever becomes too crowded or too hot, we might need to find a new home. Mars is one of the best options because it’s close to Earth, but it would be very hard to live there. We would need space suits, special houses, and lots of food and water.
The Mystery Continues!
Even though we haven’t found aliens yet, the search for life in space is exciting! Scientists are always discovering new things about our universe. Maybe one day, we will find out that we are not alone.
So, what do you think? Do you believe there is life on other planets? Keep looking up at the stars and wondering, because the universe is full of amazing mysteries waiting to be solved!
