Radio astronomers image sky at 144 MHz in more detail

Posted: 27 Jan 2022 12:55 PM PST https://ei7gl.blogspot.com/2022/01/radio-astronomers-image-night-sky-at.html


I came across an interesting article today about how radio astronomers are
in the process of plotting the radio sources of the northern sky in more
detail at 144 MHz.

The problem up to now is that the ionosphere slightly distorts the signal
at 144 MHz and that impacts the resolution of the radio image. A team of
radio astronomers have now worked out a way to compensate for this
distortion which allows resolution of radio sources at much greater detail. Some of these are shown above.
The paper was published in Nature Astronomy on the 27th of January 2022 and
a preview can be seen HERE
