国立天文台で、宇宙を身近に感じてみませんか。

One may believe the heavens are visible only from the remote countryside, but even in urban areas where city lights interfere with the dark sky, the Universe still stretches out above us.
For this reason, Stargazing Parties are held each month at NAOJ Mitaka Campus.

Why not explore the celestial objects which can be enjoyed through an astronomical telescope each season while learning how much we know about the true nature of distant objects?

The experience of looking up at the sky and witnessing celestial phenomena and the motions of the heavens is related to leading edge space observations.
Please come and discover the joy of astronomy in the evening at NAOJ Mitaka Campus, an astronomy research center exploring the mysteries of the Universe.
