"We have identified the coldest star ever found to produce radio waves – a
brown dwarf too small to be a regular star and too massive to be a planet.

Our findings, published today in the Astrophysical Journal Letters, detail
the detection of pulsed radio emission from this star, called WISE J0623.

Despite being roughly the same size as Jupiter, this dwarf star has a magnetic
field much more powerful than our Sun’s. It’s joining the ranks of just a small
handful of known ultra-cool dwarfs that generate repeating radio bursts."
