I tried Google Lens to tell the answer, but it is not giving a true answer.
I am using the Android app Stellarium.

What you are seeing is a result of internal reflections within the telescope that took the image used for plotting in the app you are using.
Here is a similar image (from Google oops?)
Quoting from Internal reflections :
The bluish features in both images are internal reflections in the telescope. When there is a very bright object in the field of view, the light can reflect around inside the telescope and camera before being recorded. The artifact is blue because both examples are from blue stars. There is probably a red artifact, too, but it is much fainter and more difficult to identify. Canis Major contains the brightest star in the sky, Sirius. Vega is somewhere near the top 10 brightest stars. These are both likely to create reflection artifacts. The "spider" shaped shadow in the middle of the reflection is due to the secondary mirror of the telescope. The blue streaks near the top of the APOD image on November 30, 2005 are due to light leakage from sigma Orionis (one of the bright stars in the belt of Orion).
Additional details about this and other artifacts can be found in the YouTube video Google Sky Artifacts - Blue Donuts In Outer Space.
