Which Telescope Better Higher Resolution: Hubble or VLBA?
(200 words excerpt, click title or image to see full post)

Question: Which telescope can see farther in space (higher resolution)? : The Hubble Space Telescope at the optical wavelengths, OR the VLBA extending from Hawaii to VA, observing at the radio wavelengths? – Sekar
Answer: The Hubble Space Telescope (HST) has a highest resolution of about 0.03 arcseconds, while the Very Long Baseline Array (VLBA) makes images with a resolution smaller than 0.001 arcsec. So, the VLBA has the HST beat when it comes to picture resolution.
