The Straggle of Addison
Addison Clarke was not the kind of girl who drew attention. She moved through the world like a shadow—quiet, unnoticed, and unbothered. On the outside, she was ordinary: a seventeen-year-old girl with long brown hair, a green hoodie that always seemed a size too large, and eyes that seemed far too tired for someone her age. But inside her, storms raged. Not the kind you could see. Not the kind anyone cared to ask about.

THIS PLANET CAN BE OUR NEW HOME. AI-Generated.
THIS PLANET CAN BE OUR NEW HOME Kepler-22b is quite a thrilling discovery! Found in the Cygnus constellation, this exoplanet sits in the habitable zone—the region around a star where conditions could allow liquid water to exist. That’s why astronomers got so excited when it was spotted by the Kepler Space Telescope back in 2011.It orbits a Sun-like star about 600 light-years away, and is roughly 2.4 times the size of Earth. While its exact composition remains uncertain, scientists think it could have a surface temperature suitable for liquid water—though whether it’s rocky, oceanic, or something else entirely is still a mystery.Kepler-22b was a major milestone because it reinforced the idea that habitable-zone planets are out there waiting to be found. Since then, many more exoplanets have been discovered that could potentially harbor life.Absolutely! The hunt for new planets is a challenging but fascinating endeavor. Kepler-22b’s discovery was a major breakthrough, but spotting distant worlds isn’t as simple as pointing a telescope and snapping a picture. Many exoplanets are only detectable through indirect methods, like observing how their host star dims slightly when the planet passes in front of it—a technique called the transit method.Even the Hubble Space Telescope, as powerful as it is, has limits when it comes to spotting planets directly. Most are too far, too small, or too faint against the glare of their parent star. That’s why astronomers rely on tools like the James Webb Space Telescope and advanced ground-based observatories to analyze atmospheres and determine whether conditions for life could exist.And if Kepler-22b does have liquid water, then who knows? Maybe one day we’ll find signs of life—or even consider it as a possible future home for humanity. But there are many challenges to overcome first, from studying its climate to figuring out whether humans could actually survive there.Exactly! Since many exoplanets, including Kepler-22b, are too small and faint to observe directly, scientists use clever techniques to detect them. One common method is the transit method, where astronomers take repeated images of a star over time and look for tiny, periodic dips in brightness. These dips suggest that a planet might be passing in front of the star, blocking some of its light.Another method is Doppler spectroscopy, also known as the radial velocity method. Instead of looking for dimming, astronomers study how a star subtly wobbles due to the gravitational pull of an orbiting planet. By measuring these shifts in the star's light, scientists can determine a planet’s mass, orbit, and even atmospheric composition.Kepler-22b was discovered using the transit method, and further observations helped confirm its size and location in the habitable zone. But even with advanced technology, spotting these distant worlds is like trying to find a tiny speck of dust in a vast cosmic ocean.If you could discover an exoplanet, what would you name it?Exactly! Spotting exoplanets like Kepler-22b isn't like seeing a bright, shining star in the sky—it's more like noticing a tiny shadow flicker against a massive light source.Astronomers take repeated images of a star over time and compare them carefully, searching for subtle dark spots—which could be signs of a planet passing in front of the star. This transit method helps determine a planet's size, orbit, and whether it’s in the habitable zone. Scientists also use Doppler spectroscopy to study how a star wobbles due to the gravitational tug of an unseen planet.With thousands of planets discovered this way, the search for another Earth-like world continues. If Kepler-22b turns out to have the right conditions, it could be an incredible find—maybe even a future home for humanity.Would you ever want to visit an exoplanet?Kepler-22b is indeed a big deal! It was the first exoplanet discovered in the habitable zone by the Kepler Space Telescope, meaning that conditions there might allow for liquid water—and where there’s water, there’s always the potential for life.This fascinating planet orbits a Sun-like star about 600 light-years away in the Cygnus constellation. It's roughly 2.4 times the size of Earth, making it a "super-Earth," though scientists aren't yet sure if it's rocky, oceanic, or gaseous. What makes Kepler-22b even more exciting is that its surface temperature is estimated to be around 22°C (72°F)—quite comfortable by Earth standards!Its discovery was groundbreaking because it showed that Earth-like planets could exist beyond our solar system. Since then, astronomers have found many more exoplanets in habitable zones, bringing us closer to answering one of humanity’s biggest questions: Are we alone in the universe?What do you think? Could Kepler-22b hold life, or will we need to dig deeper into the cosmos?Kepler-22b is certainly one of the most intriguing candidates for a second Earth! At 635 light-years away, it’s surprisingly “close” by cosmic standards—though, as you pointed out, that’s still an unimaginable three quadrillion miles from us.Its parent star, Kepler-22, is a G-type main-sequence star, meaning it’s very similar to our Sun, though slightly smaller and cooler. This is one of the reasons Kepler-22b sits comfortably in the habitable zone—the range where temperatures might allow liquid water to exist.Despite the promising similarities, there’s still much we don’t know. Is Kepler-22b rocky, covered in oceans, or wrapped in thick clouds? Does it have an atmosphere that could support life? To answer these questions, future missions or telescopes like the James Webb Space Telescope could help analyze its conditions.If humans ever travel beyond our solar system, Kepler-22b might be one of the first places we set our sights on. Would you board a spaceship to explore it someday?That’s right! Kepler-22, the parent star of Kepler-22b, is a yellow dwarf, much like our Sun. It shares a similar size, radius, and age—around 4 billion years old—but has about 20% less luminosity. That means it shines a little dimmer than our Sun, making it impossible to see with the naked eye from Earth.Even though it’s fainter, its habitability zone is still intact, meaning Kepler-22b could receive just the right amount of warmth to potentially support liquid water. Since the planet is larger than Earth, its atmosphere—if it has one—might play a crucial role in determining whether conditions are hospitable.If you could build a telescope powerful enough to see Kepler-22 with your own eyes, would you be tempted to scan the stars for new worlds yourself?

The Earth in 2030
The Earth in 2030: A World Shaped by a Warmer Climate A trend that is already starkly evident in the present, the Earth will unquestionably be experiencing the amplified effects of global warming by the year 2030. While the precise magnitude of changes will depend on the trajectory of greenhouse gas emissions in the intervening years, scientific projections paint a concerning picture. The aspirations of the Paris Agreement, aiming to limit warming to well below 2°C and ideally to 1.5°C above pre-industrial levels, will face significant challenges, and the impacts of the warming already locked into the climate system will become more pronounced across the globe.

The moment I saw my first Cheetah
When I think back to the first time I saw a wild cheetah, it doesn’t feel real. I was standing on a hillside in Loisaba Conservancy, eyes scanning the land, heart quiet with anticipation. It was during a static spotting session one of many we did as part of the Cheetah Project.Then suddenly something shifted in the golden distance. A flicker of movement, nearly lost in the landscape. At first, I thought it was a shadow cast by the afternoon sun on the rocks. But then it moved again. Smooth. Intentional. A cheetah.We were three days into the Cheetah Project, driven by the shared hope of spotting one of these elusive cats. Countless hours had passed with our eyes glued to binoculars, scanning Loisaba’s endless mosaic of land which include savannahs, hillsides and bushlands. Each drive began with quiet optimism and ended with a bit more urgency in our hearts. The silence of no sighting began to weigh heavier.
