This is because the camera was made up of four light detectors with overlapping fields of view, one of which gave a higher magnification than the other three. The Wide Field and Planetary Camera 2 (WFPC2), which was operational between 19, produced images with an unusual staircase-like shape. Hubble has a number of instruments on board - essentially, advanced digital cameras - that have been regularly upgraded and replaced during the five servicing missions to Hubble. Top Why do some Hubble pictures have a strange staircase-like shape? Nearly 4000 observing programmes have been carried out or are pending since launch in 1990. In Summer 2011, Hubble passed the landmark of its millionth observation, by making a spectroscopic analysis of the atmosphere of exoplanet HAT-P-7b. How are the Hubble images in the image archive created?ġ How many observations has Hubble made over the years?.As the Big Bang could be similar to a conventional blast, and therefore the Universe developed around it, how is possible to state that there is not a centre of the Universe? How is possible to take a picture of the most ancient radiation and see it as it were around the photographers (Hubble and then us)?.Given the latest advances in Hubble instrumentation, image processing etc., what would the absolute theoretical limit for the smallest object visible on the Moon be?.Can Hubble take a picture of the landing site of the Apollo missions?.What has Hubble found out about the beginning of the Universe?.What will be better about the James Webb Space Telescope?.If the Hubble Space Telescope pointed to Earth, what resolution would the images have?.I heard that Hubble had problems during its first few years.
