Sharpest radio image ever taken of newly discovered space object
Click for full image.
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.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

I don’t think this qualifies as the uncertainties in science, but the unknowns in science.
However in this case it is not unknown…I have seen this object scores of times on Star Trek!
It looks TOS era. I see an evil brat smiling-a cap on his head.
Looks like one of those “Giant Talking Heads” that rule the Universe in all those scifi movies! And like Jeff Wright, my FIRST thought was a fat kid wearing a hat!
