In 2025, a giant space telescope spotted a strange planet that looks squished like a lemon and is covered in dark, sooty clouds, all while zooming around its star in less than a day.
Scientists call planets that circle around stars other than our own Sun exoplanets. Since 2025's space telescope discoveries included a strange lemon-shaped exoplanet covered in dark, sooty clouds, racing around its star in less than a day, exoplanets clearly can look very different from the planets in our own solar system.
Sandcastles and snowflakes are fun, familiar things, but neither is a real scientific term for planets orbiting other stars — only 'exoplanet' describes that specific idea of a world beyond our own Sun's family of planets.
Thousands of exoplanets have been discovered so far, and they come in astonishing variety — some are scorching hot, some are shaped strangely by their star's gravity, and telescopes keep finding stranger and stranger ones the more they search the sky.
