ORCs are vast, faint rings of radio energy that surround galaxies and can be detected only in radio wavelengths of the electromagnetic spectrum. They are made up of fast-moving, magnetized plasma.

The principle of this work is demonstrated by using a laser to levitated nanoparticles and make them carry an electric charge to become an antenna that receives an external electric field containing a ...

Astronomers have found the most distant and energetic “odd radio circle” ever detected — a massive double-ringed radio structure nearly 10 billion years old. The discovery, made with the help of ...

The most distant and most powerful "odd radio circle" (ORC) known so far has been discovered by astronomers. These curious ...

Astronomers discover the most distant and powerful odd radio circle, reshaping theories about cosmic structures.s ...
