Astronomers have recently discovered an unusually low-density super-Earth orbiting a star 40 light-years away! This new exoplanet, known as NGTS-4b, is about the size of Neptune but is only about half as dense. This means that the exoplanet must have a much lower density than the ice giants in our Solar System, likely due to a thick atmosphere or an extended hydrogen envelope. It is also the first planet of its kind to be discovered orbiting a star of this type, which has given astronomers a unique opportunity to learn more about how planets form and evolve. This discovery provides an important insight into the diversity of exoplanets and opens up new avenues of research into how planets are formed.
