This is remarkable considering how short a time (on a Universe scale) it takes for planets to form. Planets form in tens of millions of years.
I'm excited to see what they discover over the next 4 years. They haven't yet found orbital motion, and are going to do follow-up observations to check for it.
In addition to those confused by the "The data suggest that the planet’s atmosphere is cloudy." statement. The article just cherry picked a phrase from the paper. It just means, looking at evolutionary models of early stage planet predictions, the light produced by this object is most consistent with "a young
planetary-mass body with a dusty or cloudy atmosphere".

So presumably, if you looked at a couple thousand young stars undergoing planet formation you should be able to find at least one, right?
- sohkamyung 8y agoNot so easy, I believe. Those "couple thousand young stars undergoing planet formation" also have to be relatively nearby for our current-day (or near future) telescopes to be able observe the planets forming. Depending on how far the telescopes can see, there might not be thousands of young stars near enough for planetary formation to be seen.
