Galactic Frost Descent

Prompt

A surreal ice cavern in  portrait. The upper third features a massive opening revealing a vibrant galaxy nebula with true #000000 deep black space. A sleek brushed metal spacecraft hovers silently in the middle ground. The bottom half is filled with stalagmites encrusted in sparkling ice crystals. Clad in reflective suits, small astronauts explore the cavern floor. Lateral margins are dark ice walls. No watermark, no logo, no signature, no text, no UI, no mobile screen, no device frames, no interface elements, no artifacts, no borders, no margins, no cropping, no cut-off parts.
