The new planet orbits an infant star, called TW Hydrae (TW Hya), which is thought to have formed between eight and ten million years ago.
The planet would have formed shortly after the birth of the star and it is possible that other planets are forming within the disc. The star is 180 million light years from Earth. On Earth at that time, chimpanzees were splitting from gorillas to form a branch of the ape family tree that led to the evolution of human beings. Dinosaurs had been extinct for 50 million years.
Star systems are thought to form amid clouds of dust and gas, and the discovery of the planet is expected to provide insights into the mechanisms.
Similarly, at a distance of more than 20,000 light years from Earth, it is probably the most distant such planet yet found, said study co-author David Bennett of the University of Notre Dame.
Exoplanet is smallest, farthest yet to be found

I struggle a little with time and distance traveled through space, but from what I gather 180million light years would mean that it would take 180million years for the light to travel to us from the discovered planet, so surely the planet must be at least 180million years old? If it was only 100million years old we would not be able to spot it for another 80million years.
