Planets are usually not much older than the stars around which they revolve. Take the sun: It was born 4.6 billion years ago, and not long after that, Earth developed. But KU Leuven astronomers have discovered that a completely different scenario is also possible. Even if they are near death, some types of stars can possibly still form planets. If this is confirmed, theories on planet formation will need to be adjusted.
