Wow. For once a story based on observations! And a picture that's a photograph instead of an artist's conception! You guys are starting to take all the fun out of cosmology. And now the major prize: Anyone who can directly image an actual planet, especially an earth type "M".

"They were able to determine the chemical composition and size of the sand-like particles."

Well……..?
That's how it ends?
Come on, the whole point of the story is that now they can figure that out, and that they *have* figured that out for this system. Why not just tell us? It would take 2 more sentences.

Sand is dense, what would cause tiny dust/molecular particles to fuse to something that heavy in a weightless environment? Not the long winded scientific process please…

Is this the same story, with different actors?
If yes, good mileage!
What would the spectrum of "sand" look like?

This is a fantastic discovery. Any evidence which supports popular theory is certainly a good thing when it comes to our growing understanding of the universe. We're on the right track…
