Astronomers have found something amazing! They have discovered 85 possible planets outside our solar system that might have just the right temperature for life to survive. These planets are called exoplanets and are similar in size to big planets like Jupiter, Saturn, and Neptune. The scientists used a special tool called NASA's Transitioning Exoplanet Survey Satellite (TESS) to make these discoveries.
TESS helps scientists study stars by looking for changes in their brightness. When something passes in front of a star, it causes a dip in its brightness. This is called a transit. Normally, scientists need to see at least three transits to find an exoplanet, which tells them how long the planet takes to go around its star. But in this study, the researchers looked at systems with only two transits. This helped them find exoplanets that take longer to orbit their star and are cooler.
Out of the 85 possible exoplanets, some are at just the right distance from their star to have the right temperature for life to exist. This is called the "habitable zone." However, the scientists still need more evidence to confirm that these are indeed exoplanets. They hope to do this by making more observations in the future.
The research team discovered 60 new potential exoplanets, while 25 were detected by other scientists using different methods. They ran a special program to search for transits on 1.4 million stars. After a careful process of checking, they found 85 systems that might have exoplanets with two transits.
Professor Daniel Bayliss, one of the scientists involved in the research, said it is very exciting to find these planets. He also mentioned that they have shared their discoveries with other astronomers so that they can study these unique exoplanets in more detail. The team hopes this will lead to further research and understanding of these fascinating planets.

My name is Aoife and I am 8 years old. I live in a small town called Galway in Ireland. Today, I want to tell you about an average day in my life. I love learning about space, and recently at school, we started studying about exoplanets beyond our solar system. It's so fascinating!
In the morning, after having breakfast with my family, I head to school. Today, our teacher talked about how scientists search for exoplanets using powerful telescopes. We even got to see pictures of some real exoplanets! It was mind-blowing to think that there are planets out there, far away from our solar system.
During lunch break, my friends and I played a game where we pretended to be astronauts exploring exoplanets. It was so much fun, imagining all the different landscapes and creatures we might find on those distant planets.
In the afternoon, we had a science experiment. We created our own mini exoplanets using colored water, oil, and glitter. It was messy but exciting! We learned how these exoplanets can be made of different materials and have different atmospheres.
After school, I went to the library and borrowed a book about exoplanets. I couldn't wait to read it and learn even more about the fascinating universe beyond our solar system.

Good evening, young explorers! Welcome to the Galactic News, where we bring you the latest updates from the vast universe. Today, we have an exciting discovery to share with you. Scientists have found planets beyond our Solar System, called exoplanets!
In a recent space mission, astronomers used powerful telescopes to detect these distant planets. They observed tiny wobbles in the stars' positions, indicating the presence of exoplanets. Can you imagine how amazing that is?
These exoplanets come in all shapes and sizes. Some are huge gas giants, while others are rocky like our Earth. Scientists believe that some exoplanets might even have conditions suitable for life!
Discovering exoplanets is like finding new worlds to explore. It helps us understand more about the vastness of the universe and the possibility of life beyond our Solar System. Who knows, maybe someday we'll visit these exoplanets and meet extraterrestrial creatures!

Exploring the Universe: Discovering Exoplanets beyond our Solar System is an exciting field of study that has captivated scientists around the world. One true event associated with this topic happened in Ireland in 1995. Two astronomers, Dr. Michael Mayor and Dr. Didier Queloz, made a groundbreaking discovery at the Observatoire de Haute-Provence in France, which was later confirmed by observations from the Roque de los Muchachos Observatory in La Palma, Spain.
They found the first evidence of an exoplanet, a planet outside our solar system, orbiting a star named 51 Pegasi. This discovery challenged the traditional understanding of planet formation and opened up a new era in astronomy. The exoplanet, named 51 Pegasi b, is a gas giant similar to Jupiter but with a much shorter orbital period, completing one orbit around its star in just 4.2 Earth days.
