Can I use adapted lenses on the om system om 3 astro?

The site doesn't cover adapted lenses, so I can't tell you how a lens from another mount would work on the OM System OM-3 Astro. What I can tell you is that it takes Micro Four Thirds lenses, and its catalogue page lists plenty of them.

For night-sky work, I'd start with fast, wide native lenses. The Voigtländer Nokton 10.5mm f/0.95 Aspherical is the fastest option here. If you want something lighter, the Laowa 10mm f/2 Zero-D MFT is a wide alternative. For a bit more reach, the Sigma 16mm f/1.4 DC DN Contemporary is also fast. For the mount itself, see the Micro Four Thirds guide.
