"A very magical place to visit and walk around 😎❤️ in the fall there is tiny but beautiful flowers and also interesting insects to see. In the winter the radio telescopes look awesome next to the snow covered Sierra mountain range 😍❤️ the stars are brilliant at night around this whole valley because big pine is a small town with very little light pollution 😎"

"Enjoyed the free Open House here this morning! Finally got to see it up close, instead of just driving past on 395. Apparently this was the first Open House since COVID so there were a lot of people there. If you missed it, look on their webpage for other educational opportunities."

Due to the sensitive nature of radio astronomy and potential interference, drone usage is likely prohibited. Always check observatory regulations before flying.
🎫 🌌 Astronomy & Science
OVRO is a leading facility for radio astronomy, studying phenomena like quasars, active galactic nuclei, and the cosmic microwave background. They use large radio antennas to capture signals from space.
While the large dishes might spark such thoughts, scientists at OVRO are primarily focused on understanding the fundamental workings of the universe, not specifically searching for extraterrestrial life.
The VLBA is a network of radio telescopes across the globe that work together as one giant telescope, providing extremely high-resolution images of cosmic objects. OVRO hosts one of these dishes.
Radio telescopes collect radio waves emitted by celestial objects. These waves are then processed by computers to create images and gather data about the universe's composition and evolution.
Yes, during open houses or guided tours, scientists and staff often share information about their research. Their website also provides educational resources.
For Different Travelers
Tailored advice for your travel style
👨👩👧 Families with Kids

The Engineering Marvels: OVRO's Dishes
These dishes are not just for show; they are sophisticated instruments crucial for astronomical research. They are part of projects like the Very Long Baseline Array (VLBA), which links telescopes across vast distances to achieve unparalleled resolution. The precision required to align and operate these massive structures is a testament to human ingenuity in the field of science and engineering.
Visitors often express amazement at the sight of these 'big ears' pointed towards the sky. The contrast between the advanced technology of the telescopes and the rugged natural beauty of the Eastern Sierra Nevada mountains creates a unique and memorable visual experience.
Capturing the Cosmos: Photography at OVRO
However, the real magic often happens after dark. The Owens Valley, particularly around Big Pine, is renowned for its exceptionally dark skies, making it a prime location for astrophotography. Visitors have captured stunning images of the Milky Way arching over the observatory dishes, creating surreal and breathtaking scenes.
When planning a photography trip, consider visiting during a full moon for softer light on the dishes, or during a new moon for the darkest skies. Remember to check for any specific photography guidelines or restrictions the observatory may have in place.
A Glimpse into the Universe: OVRO's Scientific Mission
Their work contributes to our understanding of everything from the formation of galaxies and the evolution of stars to the very origins of the universe. Projects like the Caltech Optical Astronomy program utilize OVRO for its unique capabilities, pushing the boundaries of scientific discovery.
While not actively searching for aliens, the observatory's mission is to unravel the mysteries of the cosmos. Visitors who attend open houses or tours often leave with a newfound appreciation for the vastness of space and the dedication of the scientists working to explore it.
