What radio dish has the highest resolution?
The world’s most powerful radio telescope, in its combination of sensitivity, resolution, and versatility, is the Very Large Array (VLA) located on the plains of San Agustin near Socorro, in central New Mexico, U.S. The VLA consists of 27 parabolic antennas, each measuring 25 metres (82 feet) in diameter.
Why is Hubble telescope blurry?
Shortly after the Hubble Space Telescope’s launch in 1990, operators discovered that the observatory’s primary mirror had an aberration that affected the clarity of the telescope’s early images. The result was a mirror with an aberration one-50th the thickness of a human hair, in the grinding of the mirror.

Which radio telescope is set up at?
Giant Metrewave Radio Telescope
Setup at Narayangaon near Pune, Maharashtra, the Giant Metrewave Radio Telescope (GMRT) comprising 30 fully steerable antennas each of 45m diameter and spread over an area of 25km in a Y-shaped array, is the world’s largest radio telescope in the metre wavelength region.
Does the Hubble telescope use mirrors?
Hubble uses two mirrors, laid out in a Cassegrain telescope design, to collect and focus light. After light travels down the length of the telescope, it hits the concave, or bowl-shaped, primary mirror.
Is the Hubble broken?
