Have you ever wondered what it would be like to explore strange new worlds? The Starship Enterprise from “Star Trek” might be on a mission to do just that, but in real life, scientists are discovering some truly fascinating and sometimes alarming exoplanets.
Exoplanets are planets that orbit stars outside our solar system. Thanks to advanced technology, astronomers are finding all sorts of alien worlds. Some of these planets orbit two stars, some might be similar to Earth and could even host life, and others have exotic atmospheres with clouds forming on hot Jupiters. It’s an exciting journey of discovery!
One of the most intriguing exoplanets is 55 Cancri e, located about 40 light-years away. This planet is known as a super-Earth because it has eight times the mass of our planet. It’s extremely hot due to its proximity to its star, so hot that water and other fluids can’t exist as liquids. Instead, they might be in a “supercritical state,” where they behave in unusual ways. This means that strange, superheated fluids could be oozing from beneath its surface!
To make things even more interesting, the Hubble Space Telescope has detected possible traces of hydrogen cyanide on 55 Cancri e, which means this planet might be oozing toxic fluids!
Another fascinating exoplanet is CoRoT-2a, a “hot Jupiter” that orbits very close to its star. This planet is so hot that it has become bloated, and powerful X-rays from its star cause it to lose about 5 million tons of material into space every second. It’s like a scene from “Indiana Jones and the Raiders of the Lost Ark” where things get intense!
Kepler-19b is an exoplanet about 650 light-years away with a peculiar orbit. It speeds up and slows down, which is unusual for a planet. Scientists think there might be another unseen planet using its gravity to affect Kepler-19b’s orbit. This phenomenon has helped astronomers discover more exoplanets using a method called “transit timing variations.”
The star system of Fomalhaut has gained attention because of its massive planet, Fomalhaut b. This planet is located in the debris surrounding a young star, about 25 light-years from Earth. The debris makes the star system look like a famous fictional eye, and Fomalhaut b is a rare example of a directly-imaged exoplanet!
It’s amazing to think that just 20 years ago, we didn’t know there were any planets outside our solar system. Now, we have potentially thousands of them, each with its own unique characteristics. Some of these worlds are extreme and mysterious, sparking our curiosity and imagination.

One planet that’s been in the spotlight recently is Proxima b. It’s very close to us and might be Earth-like, but we’re still learning more about it. Discover all the fascinating facts about this historic find in the video linked here.

Imagine you are an astronomer who has just discovered a new exoplanet. Design your own exoplanet by considering its size, orbit, atmosphere, and any unique features it might have. Draw a picture of your exoplanet and write a short description explaining its characteristics and how it compares to the exoplanets discussed in the article.
Choose one of the exoplanets mentioned in the article, such as 55 Cancri e or Kepler-19b. Conduct further research on your chosen exoplanet and create a presentation to share with the class. Include information on its discovery, characteristics, and any recent findings. Be sure to explain why you find this exoplanet intriguing.
Participate in an online simulation game that allows you to explore different exoplanets and their environments. As you play, take notes on the different types of exoplanets you encounter and how they compare to those in our solar system. Afterward, discuss with your classmates what you learned and which exoplanet was the most surprising.
Engage in a class debate about the possibility of life on exoplanets. Divide into two groups: one supporting the idea that life could exist on exoplanets and the other arguing against it. Use evidence from the article and additional research to support your arguments. After the debate, reflect on what you learned from both sides.
Create a travel brochure for a fictional space tourism company offering trips to one of the exoplanets mentioned in the article. Include details about the planet’s environment, what tourists might experience, and any precautions they should take. Use your creativity to make the brochure visually appealing and informative.
Sure! Here’s a sanitized version of the transcript:

The Starship Enterprise’s mission is to explore strange new worlds, but some of these “strange new worlds” are exoplanetary phenomena that could be quite alarming.
Hello, planetary bodies! Trace here for DNews. Out there, in the deepest corners of our galaxy, are some of the most fascinating exoplanetary discoveries. We’re finding alien worlds orbiting two stars, possibly Earth-like planets that may host life, and we’re even detecting clouds condensing in the atmospheres of exotic hot Jupiters! It’s an amazing and profound voyage of discovery.
However, as we learn more about some of these exoplanets, they can sound quite unsettling. For example, 55 Cancri e might be oozing and toxic! Located about 40 light-years away, this exoplanet is classified as a super-Earth, with eight times the mass of Earth. It’s extremely hot because it’s so close to its star; so hot, in fact, that water and other fluids can’t exist in a liquid state. After taking density measurements of this hot world, astronomers realized that these fluids could be in what is known as a “supercritical state,” meaning the fluid is so hot and under so much pressure that it behaves unusually. This exotic fluid might be oozing from below the surface of 55 Cancri e!
And if that weren’t concerning enough, the Hubble Space Telescope detected possible hints of hydrogen cyanide. So yes, this planet might ooze superheated fluid that is toxic! But it’s not alone in its peculiarities.
Do you remember that scene from “Indiana Jones and the Raiders of the Lost Ark” when they open the Ark of the Covenant? Well, that’s somewhat similar to the fate of CoRoT-2a. This exoplanet experiences extreme conditions every day. This “hot Jupiter” orbits very close to its star and has become bloated due to intense heating, but the powerful X-rays blasting from its star cause an estimated 5 million tons of material to be shed into space off the planet every second.
You might wonder, when is CoRoT-2a going to disappear? We’re not sure… but the Kepler-19 star system might have an unseen planet! Around 650 light-years from Earth, an exoplanet called Kepler-19b has been observed. It has a strange orbit where it occasionally speeds up and then slows down. Orbital dynamicists might think, “this is impossible.” Planets don’t just slow down and speed up on their own! In reality, though, they can, but it suggests there’s an unseen alien world that is using its gravity to influence Kepler-19b from a distance.
Tracking the orbital oddities in exoplanets has actually helped us discover more exoplanets through a method called “transit timing variations.” So, while these exo-phenomena might be eerie, they’re also quite fascinating.
Now, let’s talk about the star system of Fomalhaut. This star system has garnered a lot of attention in recent years for its massive planet Fomalhaut b. It appears to be located in the debris surrounding a young star 25 light-years from Earth. The debris makes images of the star system resemble a well-known fictional eye. So, even though Fomalhaut b is just a small part of this image, it’s a rare example of a directly-imaged exoplanet!
It’s incredible to think that only about 20 years ago, we didn’t know there were any planets outside of our solar system, and now we have potentially thousands! With such a variety, some of these worlds could be quite extreme.
If you enjoy thrilling experiences, you might also be interested in video games. But are those video games beneficial for your brain? The Science Channel explores this in the show “Your Brain On Video Games.” Check it out on November 1st at 9/8c on Science.
A planet you’ve heard a lot about lately is Proxima b. It’s very close, and it might be Earth-like, or maybe not. Discover all the exoplanetary facts about this historic find in the video linked here.
