The Cosmos-inspired designs created from a beauty of the stars
As written, this is a sentence fragment not a sentence and so is incorrect.
The main problem is that "created" is a transitive verb, which means that it needs a direct object. In your sentence the word after "created" is "from" which is a preposition. This introduces an indirect object which is not correct.
There are a couple of smaller problems, too. First, it is unusual for "beauty" to be used as a countable noun. (It's possible when describing a single person, animal or thing that is especially beautiful, but not very common and it would not be natural in this case.) Second, as written these words don't have an obvious meaning (at least to me).
There are two ways you could "fix" these issues:
1. The cosmos-inspired designs created
from abeauty offrom the stars.
2. The cosmos-inspired designs created from
athe beauty of the stars were extremely attractive.
Unfortunately, although these two sentences are now grammatically correct, the meaning is still not exactly clear. My sense of what you are trying to say is something like:
These designs were inspired by the beauty of the cosmos / stars.
Is that what you wanted to say?
I hope this helps.
