Scientific Results
Some of the scientific results derived from VLBI include:
- Imaging particle emissions from distant sources. (See quasar, blazar)
- Imaging the surfaces of nearby stars at radio wavelengths (see also interferometry) – similar techniques have also been used to make infrared and optical images of stellar surfaces
- Definition of the celestial reference frame
- Motion of the Earth's tectonic plates
- Regional deformation and local uplift or subsidence.
- Variations in the Earth's orientation and length of day.
- Maintenance of the terrestrial reference frame
- Measurement of gravitational forces of the Sun and Moon on the Earth and the deep structure of the Earth
- Improvement of atmospheric models
- Measurement of the fundamental speed of gravity
- The tracking of the Huygens probe as it passed through Titan's atmosphere, allowing wind velocity measurements

Famous quotes containing the words scientific and/or results:
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
“Being a parent is unlike any previous job—the results of any one action are not clearly visible for a long time, if at all.”
—Anonymous Mother. As quoted in Between Generations by Ellen Galinsky, ch. 2 (1981)
