Just how do scientists know that the "cloud" in that photo is a cloud and not a curtain-like disc? If a disc of dust were turning toward a 90 degree angle to your view, wouldn't it APPEAR to be shrinking in size? Of course it would.
Now, the goal would be to wait and see if the "cloud" becomes narrow in one dimension, call it the "X" length (width) while remaining the same in it's "Y" length (vertical) or the opposite reference. We can debate this point again in 1,000 to 1 million years from today.
Because there just happens to be many different types of photography, my friend! Not only can they discern it as a gas cloud, they can tell you what the major gases and even the minor gases are. Also, there are many types of telescopes, and we are able to discern many features by using them. Also, we can take a series of photos and then analyze the photos to discern movement. From the movement we can tell what a particular gas cloud is up to and in this particular case, it's turning into a star. Therefore it's not necessary to debate this point 1,000 to 1,000,000,000 million years in the future.
Your friend;

Just educated guesses.
