Best Ever Image of a Far away Star's Surface Captured

Its a blur,

a blurry digital composite photograph.

the stars disk isn't even circular.

Unlike your logic.

I'm looking forward to the future imaging regardless of the target, the whole thing is fascinating.

Looks fake to me........

Real enough... the result of all that 'imaging' didn't produce much useable data.

It actually did. "First map of motion of material on a star other than the Sun" www.eso.org...

Using the new results the team has created the first two-dimensional velocity map of the atmosphere of a star other than the Sun. They did this using the VLTI with three of the Auxiliary Telescopes and an instrument called AMBER to make separate images of the surface of Antares over a small range of infrared wavelengths. The team then used these data to calculate the difference between the speed of the atmospheric gas at different positions on the star and the average speed over the entire star [2]. This resulted in a map of the relative speed of the atmospheric gas across the entire disc of Antares — the first ever created for a star other than the Sun..

The astronomers found turbulent, low-density gas much further from the star than predicted, and concluded that the movement could not result from convection [3], that is, from large-scale movement of matter which transfers energy from the core to the outer atmosphere of many stars. They reason that a new, currently unknown, process may be needed to explain these movements in the extended atmospheres of red supergiants like Antares.
