A little sun

[microplan]

Hello.
Looking at the samples before Christmas, I thought I'd see a star.
Unfortunately, nothing like that happened.
But recently I found not even a star, but a whole miniature sun.
Of course, I do not know what it is because I am not a biologist, but I decided to share my trophy with you.
As for my abilities, the video is very short because it only lasts less than 5 minutes.

It may be a tardigrade egg.

It does very much look like an egg, but I wouldn't guess more than that because of lack of knowledge. It looks to me like it is spherical rather than flat.
