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
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!
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
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.
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

It is not actually traveling faster than the speed of light (or probably isn't - if it is, then that's something really new!). It's only
apparently moving faster because of the relativistic effects of it's motion compared to our motion added together and probably other things that are
beyond my ken, since I'm not an astrophysicist. It's an illusion, an apparent speed but not its actual speed, which should be less than the speed
Einstein's theory didn't say objects couldn't travel faster than the speed of light, it only stated that objects couldn't accelerate faster
than light. It may seem like symantecs, but if something is already travelling at c or faster, it doesn't need to accelerate.
Well all galaxies when we look at them have a red shift which means they are moving away from us, and actually every Galaxy is moving away from
everyone due tot he big bang. Also the farther it moves away the faster it goes and therefore it could possibly and theoretically move faster than the
speed of light. I was curious about this and remember hearing about when taking my astronomy and astrophysics class a long time ago. here is an
article which talks about such. Galaxies traveling faster than the speed of light?
It is interesting to think about.
There are not too many things in astrophysics and astronomy that raise my eyebrows often, but this is just strange. An object emitting stable radio
signals and moving at 4 times the speed of light... Either this is a really exotic object or some sort of intelligence. Either way I'm genuinely
I'm leaning toward exotic object, but it just wouldn't surprise me to find an artificial source of this phenomenon.
You know, this really does sound intersting.
And I dont wanna be the first to jumo on the escilation band-wagon, but how many times do we hear about signals then contact...
Although this is probably nothing like that, and is just the formation of some universal body that we havnt witnessed yet.
Its a tuff one for me because I dont know nothing about nothing.
