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.

"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.


Mysterious radio waves emitted from nearby galaxy

This is pretty interesting, but check this out!

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


This is an image of the M82 Galaxy that the signal is coming from



for you google sky users M82 is located at RA 9h55m52.72s Dec 69'40'50.30" (or just search M82!)

But what could this be?

Could the object be a black hole? It is not quite in the middle of M82, where astronomers would expect to find the kind of supermassive central black hole that most other galaxies have. Which leaves the possibility that it could be a smaller-scale "microquasar".


Whatever it is, it sure is interesting, and Tom Muxlow of Jodrell Bank Centre for Astrophysics near Macclesfield, UK will report the discovery at the Royal Astronomical Society National Astronomy Meeting in Glasgow, UK, today. So I look foreward to his report!

Here is what the signal looks like

That is a perfect example of how the Standard model is totally wrong.

In the standard model as is known by many no matter could travel faster than the speed of light, but it is possible for radio waves to travel faster than light.

Device Makes Radio Waves Travel Faster Than Light



A scientist has created a gadget that can make radio waves travel faster than light. Einstein predicted that particles and information can't travel faster than the speed of light, but phenomena like radio waves are a different story, said John Singleton, who works at the Los Alamos National Laboratory.

The polarization synchrotron combines the waves with a rapidly spinning magnetic field, and the result could explain why pulsars — which are super-dense spinning stars that are a subclass of neutron stars — emit such powerful signals, a phenomenon that has baffled many scientists.


What is odd about the discovery you have highlighted is why the radio signal is constant in luminosity?

This is very odd, because quasars are basically black holes with an accretion disk that give out burst of radiation, so you would expect the signal to increase in luminosity to a peak then decrease quite quickly.

I suspect this is a new object that we have no prior understanding of.

Though to be honest this sort of thing to me screams of intelligence. It would be certainly a good way to send a large wave hello we are here signal, since it does not conform to how normal radio signals perform from known sources.

Star and Flag.

Peace Out,

Korg.

From
Wiki

Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is the prototype nearby starburst galaxy about 12 million light-years away in the constellation Ursa Major. The starburst galaxy is five times as bright as the whole Milky Way and one hundred times as bright as our galaxy's center.


Not sure about the direction though.

Them Merlin Archives stop at 2007, and this signal was found in 2009.

Hi MysterE,

A great find.

Seems astrophysicians are discovering more and more unknows recently (which I think is great!)

But four times the speed of light - what with the recent gravitational/rotational finds regarding gravity it would appear Albert's theories need to be extended/expanded?

Peace!

No kidding! When I first read that I thought that they had mis-judged the distance and therefore the speed, but then I realized were talking about astro-physicists here!
