Five Star Gift Ideas

Here are some gift ideas for your boyfriend who is interested in cosmology:

1. A telescope: if your boyfriend is interested in cosmology, he might appreciate a beginner telescope to explore the night sky.

2. A star chart: a personalized star chart showing the position of the stars on the night of your anniversary would make a romantic and thoughtful gift for your boyfriend.

3. A book on cosmology: there are many great books on cosmology that are accessible to non-experts. Look for one that introduces cosmological concepts in a way that your boyfriend can understand and enjoy.

4. A subscription to a popular science magazine: a subscription to a magazine like Scientific American or Discover that covers a range of scientific topics, including cosmology, would make a great gift for your boyfriend.

5. Custom-made constellation art: consider having a piece of art made that features the constellations associated with your anniversary date, such as a hand-drawn star map, a metal constellation piece, or a star chart poster.
