APOD: A Partial Solar Eclipse over Buenos... (2018 Feb 20)

A Partial Solar Eclipse over Buenos Aires
Explanation: What's happened to top of the Sun? Last week, parts of Earth's southern hemisphere were treated to a
partial solar eclipse, where the
Moon blocks out part of the
Sun. The
featured image was taken toward the end of the eclipse from the coast of
Uruguay overlooking
Argentina's
Buenos Aires. Light-house adorned
Farallón Island is seen in the foreground, and a plane is visible just to the left of the Sun.
The image is actually a digital combination of two consecutive exposures taken with the same camera using the same settings -- one taken of the landscape and another of the
background Sun. The
next solar eclipse visible on
Earth will be another partial eclipse occurring in mid-July and
visible from parts of southern
Australia including
Tasmania.

Anyone see evidence in this photo that the Earth is round?
Why do we have to address this matter in 2018?

We don't.

We all know that the earth is "round". It's a flat disk...

And why is it we park on a driveway and drive on a parkway?

I know. I
met one of them last November. He fancied himself a critical thinker. (Head, meet desk.)

I didn’t see these symptoms in this guy. He just honestly believed that he had research to prove the Earth is flat, that all those NASA photos were faked, and that NASA even admitted it.

This looks like a composite image to me. Isn't the sun too big compared to the surroundings? Also, the turbulence around the sun is not seen in the foreground. The foreground also seems to be shot with a wider focal length compared to the sun.
Can someone please explain how this image is possible?
Thanks and Regards,
Keerthi

Please ignore my earlier message. The description clearly says this is a composite with sun and foreground taken at different times.

Well, yes, the caption does say that. Oddly, the captions on the imager's pages doesn't seem to suggest it is anything but a single shot. That said, even if it is a composite, nothing suggests there is a different scale between the two. The Sun is correctly positioned and correctly sized with respect to the background.

Have you seen where Farallón Island is on the map in relation to Buenos Aires? The Sun is expected to appear that large at the required zoom setting for that shot. The fact that you cannot see ground level in Buenos Aires (which is what I alluded to with my round Earth comment) gives a hint of the distance from the camera to the city—about 50 km.

It is impossible that you can see the coast of Buenos Aires from the Farallón Island, the curvature of the Earth prevents it.

That depends, of course, on the height of the observer. In the case of this image, that height appears to have resulted in everything below a few tens of meters at the coastline being blocked by Earth's curvature.
