Here are some gift ideas for your boyfriend who likes cosmology:
1. Books on cosmology: Gift him a book on astrophysics or cosmology that he doesn't already have. Some popular titles in this genre are "Astrophysics for People in a Hurry" by Neil deGrasse Tyson or "A Brief History of Time" by Stephen Hawking.
2. Star projector: Get him a star projector that projects the constellations and stars onto the ceiling. This will allow him to experience the beautiful wonders of the galaxy in the comfort of his own bedroom.
3. Constellation mug: Get him a mug with a constellation of his choice. Every time he drinks his coffee or tea, he'll be reminded of his love for cosmology.
4. Astronomy calendar: Gift him an astronomy-themed calendar that highlights the important celestial events throughout the year.
5. Telescope: If your budget allows, get him a telescope so he can observe the stars and planets in the night sky. This will be an especially meaningful gift if he doesn't already have one.
Or you can get him a star map with an important date you share.
