There's something unusual lurking out in the depths of space: Astronomers have discovered four faint objects that at radio wavelengths are highly circular and brighter along their edges. And they're unlike any class of astronomical object ever seen before.
The objects, which look like distant ring-shaped islands, have been dubbed odd radio circles, or ORCs, for their shape and overall peculiarity. Astronomers don't yet know exactly how far away these ORCs are, but they could be linked to distant galaxies. All objects were found away from the Milky Way's galactic plane and are around 1 arcminute across (for comparison, the moon's diameter is 31 arcminutes).
After ruling out objects like supernovas, star-forming galaxies, planetary nebulas and gravitational lensing a magnifying effect due to the bending of space-time by nearby massive objects among other things, the astronomers speculate that the objects could be shockwaves leftover from some extragalactic event or possibly activity from a radio galaxy.
With only four of these peculiar objects discovered so far, the astronomers can't yet tease out the true nature of these structures. But the EMU survey is just beginning, and astronomers expect it to reveal more unusual objects.

Dont sweat the neutrinostheyre mostly like fairy dust. There are pions, kaons, muons, iron nuclei, and neutrons with more credence as the bad boys. Lead-polyethylene-boron composite is your friend.
Yes. Larry Niven was always good.
Maybe.
I have a question.....
That neutrino was travelling at 186,000 miles per second for 3.8 billion years, how many miles has it travelled?
These huge numbers are something else.
'Outrageously-Luminous' Galaxies Discovered 300 Trillion Times Brighter Than The Sun
I remember someone on FR explaigning to us that a trillion dollars was a stack of $100,00 bill 140 miles high.
Can you see earth in this picture? It was taken by Voyager from four billion miles away.
Man O Man!
I don't feel very significant.
I have single Zimbabwean banknotes that can easily exceed that total. :)
And....Mugabe is finally gone.
That link just now... 300 trillion times brighter than the Sun, presumably they are great big bunches of great big bright stars. Orrrr, they aren't as far away as believed. :^)
