Thumbs up Arecibo Observatory gets 7-pixel eye on the sky that will make world's most sensitive




ARECIBO, P.R.. -- The Arecibo Observatory telescope, the largest and most sensitive single dish radio telescope in the world, is about to get a good deal more sensitive.

Today (Wednesday, April 21) the telescope got a new "eye on the sky" that will turn the huge dish, operated by Cornell University for the National Science Foundation, into the equivalent of a seven-pixel radio camera.

The complex new addition to the Arecibo telescope was hauled 150 meters (492 feet) above the telescope's 1,000-foot-diameter (305 meters) reflector dish starting in the early morning hours. The device, the size of a washing machine, took 30 minutes to reach a platform inside the suspended Gregorian dome, where ultimately it will be cooled and then connected to a fiber optic transmission system leading to ultra-high speed digital signal processors. The new instrument is called ALFA (for Arecibo L-Band Feed Array) and is essentially a camera for making radio pictures of the sky. ALFA will conduct large-scale sky surveys with unprecedented sensitivity, enabling astronomers to collect data about seven times faster than at present, giving the telescope an even broader appeal to astronomers.

I whole heartedly agree with IMOG's statement. Keep it up Sir Ulli. Though I am new to the team and this forum I find the articles and information you post enjoyable to read. I look forward to more.

PS. I also enjoy the lively debates I've been reading. Oh so tempting to chime in
