We’re here to bring space closer to more people.
Once, space felt out of reach - costly equipment, remote sites, and rare knowledge kept it distant. But as tools grew smaller and better, the sky opened. That’s why we started Hα: to make the night sky part of everyday life, where anyone can capture a galaxy, understand a nebula, and feel what it means to truly see the stars.
We share guides that explain the why as much as the how, and create projects that matter - not just to science, but to those who take part. Whether you’re a beginner, returning after years away, or simply seeking something slow and real, we’re here to make that first look up clearer, easier, and yours.
Here’s what that looks like across everything we do.
- Make complex space science clear, relatable, and engaging.
-
Contribute to real, collaborative research and open projects.
-
Create events and experiences where everyone feels welcome.
-
Preserve and share space history through HαLIDE.
-
Support shared dark skies and local wildlife through LYRA‑51.
-
Grow through the support of people who share our mission.
-
Keeps science open, human, and accessible to all.
