What they did is they managed to track the light that's emitted during this process, which is red because of its ultra heated hydrogen, two teams of researchers manage to spot this planet being formed, one from the University of Arizona and one from Stanford.
Why this is a big deal? Is it's, not just the first time that scientists have been able to see this process, but what it tells us is that we might learn more about how planets are made in the future and possibly identify another earth.
