What could be the reason for these block-like artefacts in the blue sky?

I would suggest that it might actually be a sensor fault (or firmware bug). My reason for suspecting this rather than JPEG artefacts or banding is that the surrounding sky has exactly the same ...

How do I shoot birds against the sky to be faithful to their colour?

Well, in order to get good results, you'll have to make the plunge into non-auto settings. I'd recommend Manual mode. The problem you're running into here is that you are pointing your camera at a ...

What could be the reason for these block-like artefacts in the blue sky?

These look like JPEG compression artifacts, possibly caused by picking a lower-quality setting in the camera settings. On many cameras there's e.g. a Fine JPEG mode and a SuperFine mode, or something ...

Is it picture noise or did I captured the stars of our galaxy?

It looks like a severely underexposed image with heavy noise reduction applied. Minor differences between "almost black" and "totally black" have caused the patterns you see.

What camera features do I need to take a clear picture of NEOWISE?

Any camera that allows manual control of focus and manual control of exposure should be usable for astrophotography. But both of these are requirements (not just "nice to have"). There is a ...

How do I interpret weather forecasting data for landscape photography?

If you mean weather forecasts like this one it can only provide general and not-so-reliable information. It is too vague. 30% cloud coverage means that 30 % of the sky is covered by clouds. What type ...

Can I take clear night sky photographs with my smartphone?

Astrophotography is a much more complex process than you might expect it to be. The stars do put out a lot of light, but it's pretty well diffused by the time it hits Earth. You would need a long ...

What causes this leather-grain pattern of noise in the sky when I inspect with a sharp mask?

Even when the sky appears uniform to our eyes, it isn't. The index of refraction of air is affected by a number of things (e.g. the shimmering mirages you see over a hot road) - temperature, humidity, ...
