There is something strange in the cosmic neighbourhood. An unknown object in the nearby galaxy M82 has started sending out radio waves, and the emission does not look like anything seen anywhere in the universe before.

. . . Thanks Scarecrow - a note: my system shut down @ that same moment last May

& i recently figured how to 'beat' the ERROR 1714 and get iT baCk up crunChin'




"We don't know what it is," says co-discoverer Tom Muxlow of Jodrell Bank Centre for Astrophysics near Macclesfield, UK.

The thing appeared in May last year, while Muxlow and his colleagues were monitoring an unrelated stellar explosion in M82 using the MERLIN network of radio telescopes in the UK.

A bright spot of radio emission emerged over only a few days, quite rapidly in astronomical terms.

Since then it has done very little except baffle astrophysicists.

It certainly does not fit the pattern of radio emissions from supernovae: they usually get brighter over a few weeks and then fade away over months, with the spectrum of the radiation changing all the while. The new source has hardly changed in brightness over the course of a year, and its spectrum is steady.

Warp speed

Yet it does seem to be moving – and fast: its apparent sideways velocity is four times the speed of light . . .

When do we get SETI WUs from IT to crunch?!!!

One never knows. One never knows!

By the way, amazing find and thanks for the article on it.

Nice, yet more mysteries to be solved.
