1. Preheat oven to 325°F (160°C). Grease a 9-inch springform pan and line the bottom with parchment paper.

2. Mix cookie crumbs, melted butter, and sugar in a bowl. Press into the bottom of the pan. Chill while preparing the filling.

3. In a large bowl, beat cream cheese and sugar until smooth. Add eggs one at a time, mixing well after each.

4. Blend in sour cream, vanilla extract, and lemon juice until creamy.

5. Divide the batter into four bowls. Tint each with gel food coloring: one plain, one navy blue, one violet, and one black.

6. Spoon dollops of each color randomly into the crust, alternating colors for a marbled galaxy effect.

7. Use a skewer or knife to gently swirl through the batter — do not overmix.

8. Bake for 55–65 minutes, until center is just set but slightly jiggly.

9. Cool in oven with door cracked for 1 hour, then refrigerate at least 4 hours or overnight.

10. Optional: Warm jam with luster dust to make a glossy galaxy glaze and drizzle lightly over the chilled cheesecake before serving.
