Has the telescopes gotten good enough to photograph an actual disk of any star? Or are they all just points of light?

In summary, the telescopes have improved enough to photograph an actual disk of some stars, as seen in the list of resolved stars on Wikipedia. These images may use specialized techniques or non-visible wavelengths. Directly imaged exoplanets are also being discovered at an even deeper level, as seen in the provided links.

Absolutely. Several stars have been resolved. Wikipedia has a list of them here: https://en.wikipedia.org/wiki/List_of_stars_with_resolved_images
Note that some of these are not 'conventional' images, but instead use specialized techniques and/or non-visible wavelengths to generate images.

That is _freakin' cool_!
Now let's take it an order of magnitude deeper: directly imaged exoplanets:

1. Can we see individual stars as disks with the naked eye?
No, with the naked eye, we can only see stars as points of light. This is due to the vast distances between stars and the limitations of our eyesight.
2. How can we see stars as disks in photographs?
Photographs of stars are often taken with long exposure times and specialized equipment such as telescopes or cameras with high zoom capabilities. This allows for more light to be captured and for the stars to appear as disks instead of points of light.
3. Are all stars the same size when seen as disks?
No, stars come in a variety of sizes and therefore, their disks will also vary in size. Larger stars will appear bigger in photographs while smaller stars will appear smaller.
4. Can we see the true color of stars in photographs?
Yes, with advanced technology, we are able to capture the true colors of stars in photographs. However, the colors may appear different due to factors such as the atmosphere and the type of camera used.
5. Are there any limitations to seeing stars as disks in photographs?
Yes, there are limitations such as light pollution, weather conditions, and the distance of the stars. Light pollution can make it difficult to capture clear images of stars, while weather conditions such as clouds can obstruct the view. Additionally, the further away a star is, the smaller it will appear in photographs.
