Sharpest radio image ever taken of newly discovered space object

The uncertainty of science: Astronomers, using the MeerKat radio telescope in South Africa, have taken the best radio image yet of a newly discovered type of astronomical object, dubbed whimsically as an odd radio circle (ORC).
The photo to the right is that image. While it is reminiscent of the many planetary nebulae seen in visible light that astronomers have been studying since the 1800s, this weird shape is only seen in radio frequencies, and it is much much larger.
Odd radio circles are so named because they’re large, circular objects which are bright around the edges at radio wavelengths, but which can’t be seen with optical, infrared or X-ray telescopes – and at this stage, astronomers don’t really know what they are.
And they’re massive – about a million light years across, making them sixteen times larger than our own galaxy. But despite their gargantuan size, the objects are difficult to spot, hiding in plain sight.
Planetary nebulae are generally the size of solar systems.
