Many observations of the sun's corona just use a disk attached to the telescope, as you're suggesting [0]. However, for Proba-3 they want the disk to be over 100m away from the telescope, which isn't practical. Also, one of the goals of Proba-3 is to develop formation flying technology, because it will be useful for many other missions in the future.
You clearly have no idea about Turkey and the situation. Watching porn isn't persecuted. The conservetive government just forced ISPs to ban them from their DNS. It was always available by using Google DNS and the whole country does this for like 15-20 years now.
I specifically said I don't know; that's one reason I would be very careful. Notice that your response is to assume complete and correct knowledge of your own.
I do know that being LGBTQ+ is persecuted in many places, even in the US; I know what is overlooked now can be persecuted later, even many years later; I know that in most places Internet usage is recorded and is used to build detailed profiles of users, and that those records are retained indefinitely.
Depends on which part of Europe. In Spain, duvets weren't even a thing in the 80s, at least as far as I know. Everyone used sheets and blankets and/or conforters. The first time I met duvets was in foreign hotels, later Spanish hotels started using them too, and even later, laypeople started using them.
They quickly gained traction (Ikea probably had a big role there) and now both alternatives are common, although I'd say maybe duvets are already the most common.
The Spanish words for duvet and duvet cover (edredón nórdico, funda nórdica) are a testament of the fact that they used to be a foreign thing, here associated (I don't know if accurately or not) with the north of Europe.
