Can Scientists Capture Images of Distant Stars Like Betelgeuse?

[thetexan]

Have scientists ever been able to resolve the disk of a distant star in a photograph besides our own sun?

 

[Drakkith]

Yep.

[Chronos]

The discs of a number of stars have been resolved used optical interfereometry. COAST is one example.

Has there been any normal photograph of a star disk...not infrared or other unusual method...just a simple hi rez normal photograph of a star disk. If so, please give a link to the image.

Interfereometry images have very high resolution compared to ordinary photographic images. The effective aperature of the collector is many times greater than possible using any single aperature instrument.

What Chronos is saying is that an image done using interferomety is just as "normal" as a normal photograph. The ability to get higher resolution is comparable to a camera with a bigger megapixel count and a better lens.

If you go to the following length you can see a picture of Betelguese in Red light.
