How about getting her a membership to a local museum? This would give her unlimited access to exhibitions throughout the year. Additionally, you could purchase tickets to a specific exhibit or event that you know she would enjoy. To make it more personal, you could plan a day trip or outing with her to attend the museum, enjoy lunch or dinner together, and spend time talking about what you both liked about the exhibits. Another idea could be to gift her a coffee table book featuring beautiful images and information from her favorite exhibitions that she can flip through at home.
Or you can get her a star map with an important date you share.
