"VLBA Marks 30 Years Pushing the Bounds of Science"
The Very Long Baseline Array (VLBA) has now been in existence for thirty years and has been involved in several major discoveries in astronomy. One of the most important sites it has is the radio dish on Mauna Kea as it extends the baseline, increases its resolution, and fills in the coverage of the sky that's not possible without a site in Hawaii.
"The VLBA is a critical tool for astronomy, where knowing distances is the basis for figuring out the mass, makeup, and movement of cosmic objects. High-precision observations are the VLBA’s greatest strength. With the VLBA’s accuracy, astronomers:

"The VLBA is a critical tool for astronomy, where knowing distances is the basis for figuring out the mass, makeup, and movement of cosmic objects. High-precision observations are the VLBA’s greatest strength. With the VLBA’s accuracy, astronomers:
- Measure the spins and shapes of galaxies, including our Milky Way
- Collect cosmological distances to measure Dark Energy in the Universe
- Trace the movements of black holes and pulsars to learn their history and future
- Predict if and when galaxies will collide, including the Andromeda Galaxy with our Milky Way
- Provide the most accurate distances to stars
- Pinpoint the exact centers of planets in our Solar System
- Develop the celestial reference grid used by other telescopes"
