M82 Mysterious Radio Waves Emitted From Nearby Galaxy

Показать описание
'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.'


Transcript:
We begin with a composite image of the nearby starburst galaxy M82 that contains X-rays from Chandra in blue, optical data from Hubble in green and orange, and infrared data from Spitzer in red. Next we zoom into the central region of M82, where just Chandra's view is visible. There we see two bright X-ray sources of special interest. Astronomers think these may be medium-sized black holes. These "survivor" black holes seem to have avoided falling into the center of the galaxy. They could also be examples of seeds required for the growth of supermassive black holes in all galaxies, including the one in the Milky Way.

So if M82 is 11.5 million light years away, then they're already extinct anyway

But they say it traveled 4x the speed of light. And that galaxy isn't the longest distance away.

I read it was still 'visible' a year later....is it still visible now?

Did it mention anything about the object traveling 4x's the speed of light that is emitting the signals??

Oh. Actually, radio waves, x-rays and visible light are all in the same Electro-magnetic Spectrum. So they all travel at the same speed, which is the speed of light.

Nothing can go 4x the speed of light. There isn't enough mass-energy in all of the universe to accelerate even a single proton to 100% the speed of light. Time slows down as you approach the speed of light, stops AT the speed of light, and goes in reverse if you were to exceed it. Time going in reverse is really just another way of saying "it's not possible".

I thought the song at the beginning was what you were saying was the sound. I laughed, I thought I got trolled.

Always boggles the mind. Outer space is not real time.

and no one recored the radio signals?

M82 is ~11.5 million light years away. Nothing travels at 4x the speed of light. Even if you managed to get to the speed of light (and you can't; all of the mass-energy in the entire universe wouldn't be enough to accelerate even a single proton to 100% of the speed of light), time will have stopped completely for you and you'd literally be bound to inaction past that point.

lol I was just about to respond to your comment (the one on the top) and asking if it wasn't 12 years ago as its only 12 light years away. Then I read this comment and realized its 12 million light years away.

perhaps whatever it was learned that radio waves were inferior to what they now have?

What is moving 4x the speed of light?

Whatever it was, it happened millions of years ago.

No alien's here it's whether a black hole or a supernova

I don't know that it's a matter of "conquering" energy; accelerating something with positive rest mass takes an infinite amount of energy. The observable universe is a finite place, so this isn't possible, let alone feasible...

If it is possible to alter or break the laws of physics, then the implications to "reality" would be just as infinite.

Well it was moving 4x the speed of light...
