"NEW" 'Dark sun' Mysterious radio waves from nearby galaxy

[Kingz Profile]

WOW This is truly amazing, perhaps this is also the new "star" / "planet" that people are seeing... WTF All of the things are coming true now.... I seriously don't know how this heavanly body will influence our earth, and perhaps it is even the cellestial reffered to as Niburu / Nibiru / Wormwood / Etc....



'Dark sun' is one of our nearest neighbours!
A dim object less than 10 light years from Earth appears to be the closest brown dwarf yet found. The "star" is so cold that any residents on an orbiting planet would see a dark sun in their starry "daytime" sky.

The discovery suggests that brown dwarfs are common and that the objects could exist even closer to Earth. Brown dwarfs have so little mass that they never get hot enough to sustain the nuclear fusion reactions that power stars like the sun. Still, they do shine, because they glow from the heat of their formation, then cool and fade.

Philip Lucas of the University of Hertfordshire in Hatfield, UK, and his colleagues discovered the brown dwarf, named UGPS 0722-05, from the infrared radiation it gives off. It is only about 9.6 light years from Earth, a bit more than twice as far as Proxima Centauri, our nearest star after the sun. At that distance, it is the seventh closest star or star system to the sun. Not since 1947 have astronomers uncovered a new star so close to Earth.

Parallax view
"Great stuff!" says Todd Henry, a nearby-star researcher at Georgia State University in Atlanta, who was not part of the team. "This discovery is as cool as its temperature."

Lucas and his colleagues caution that their estimated distance is preliminary. It is based on parallax, which offers a reliable method of deducing a star's distance from Earth: if an observer on Earth measures the star's position in the sky and then looks at it again months later, the star will appear to have moved slightly because it is being viewed from a different point in our planet's orbit around the sun. Knowing the dimensions of Earth's orbit, astronomers can calculate the star's distance from the amount of its apparent movement.

But at the moment, Lucas and his colleagues don't have good enough parallax measurements to be sure of the brown dwarf's precise distance and could be a light year or so out. In just a few weeks, however, new parallax observations should pin the distance down. If the current distance estimate is right, the brown dwarf is closer than any other known. The previous record-holder is a pair of brown dwarfs around the star Epsilon Indi, 11.8 light years from Earth.

Record breaker
The new brown dwarf breaks two other records as well. It's the coldest brown dwarf ever seen, with a temperature of just 130 to 230 °C. And it's the dimmest: it emits only 0.000026 per cent as much energy as our sun, and this energy emerges at infrared rather than visible wavelengths. It would take 3.8 million of these brown dwarfs to equal the sun's power. It is about the size of Jupiter, but its mass is 5 to 30 times greater.

The object's feeble nature explains why it has only now been spotted, despite its proximity. It was found after surveying only a few per cent of the sky, which implies that many more brown dwarfs are lurking nearby undetected.

Whatever it is, as our science is more progressing, we will encounter more and more bizarre things.... question is how is it going to impact our life on Earth, both in "actions" and in "words"

Not the best released science article.... but disinfo > got any proof by any chance, or maybe a explenation... because of quicly adding some numbers into a file doesn't have to be disinfo

Anyway.... I already posted that planet x topic > look in my second post

Discovery of a very cool brown dwarf amongst the ten nearest stars to the Solar System

Brown dwarfs are bodies with masses in the range between those of giant planets and the lightest stars. Some are isolated, while others orbit normal stars or exist in star clusters. Since 1995, more than 100 methane brown dwarfs, or T dwarfs, have been found with spectra similar to that of the planet Jupiter and effective temperatures in the range 500-1300 K. The detection of even cooler bodies will open up a new arena for atmospheric physics and help to determine the formation rate of stars and brown dwarfs in our Galaxy as a function of both mass and of time. Here we report the discovery in the UKIDSS Galactic Plane Survey of a brown dwarf, UGPS J0722-05, that is not only far less luminous and significantly cooler than previously known objects but also the nearest to the Solar System. The measured distance is 2.9 +/- 0.4 pc, from which we deduce an effective temperature in the range 400-500 K. The Gemini/NIRI near infrared spectrum displays deeper water vapour and methane absorption bands than the coolest known T dwarfs, and an unidentified absorption feature at 1.275 microns. Time will tell whether this object is regarded as a T10 dwarf or the first example of a new spectral type.

Mathematics + Physics said: when will the angry dwarf planet already in 2012 (and maintain the bullshit-distributor), then he must not be 10 light years away ...

Hah hah hah!

...
... and perhaps it is even the cellestial reffered to as Niburu / Nibiru / Wormwood / Etc....

ZEHN LICHTJAHRE
TEN LIGHT YEARS

hey, komm wieder runter - seid ihr Nibiru-Anbeter schon so weit, das ihr jetzt schon einen 10 Lichtjahre entfernten Zwerg als "Nibiru" herbeireden müßt ?
Mathematik + Physik sagen : wenn der Zwerg unseren Planeten schon im Jahr 2012 ärgern soll (und das behaupten die Bullshit-Verbreiter) dann darf er nicht 10 Lichtjahre entfernt sein ...

hey, come back down - it Nibiru worshipers are so wide, that you now must have a dwarf 10 light years away as "Nibiru" talk themselves?

I agree i'm no expert, and I shall never be a expert.... luckily we have guys like you who can point stuff like that out..... Instead of inmediatly bashing, pleas just explain it so we can understand mate!

I admit... i'm overly excited when it comes to stuff like this.... And ok too say Nibiru or wormwood is way over the line when talking reality.... but damn, in my opinion who should we believe.....

Conventional science
Sitchin
You
Me

Exactly... i'm just pointing my thoughts out... and hopefully you could understand what I just said in my metaphorical emoticon language

I'm always willing too change my mind when I hear clear arguments

EDIT: You will never hear me say anything about 2012 or any other date dat specificly calls for some kind of "Cosmic Event"

I'm too relative for that, and too stoned.... I only do specific times when it comes to work or school > and that's it

Ok point made: Not disinfo bu a DISTRACTION, they probably new about this 20 years ago. 10 light years away! and omits little light, there seems to be a lot more detailed info here than is TOLD to us about Venus. Who cares what's 10 light years away when our own planet isn't even been fully explored or maybe intensionally hidden from us.

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.
http://www.jodrellbank.manchester.ac.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.
http://www.merlin.ac.uk/about/layman/merlin.html

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. Such apparent "superluminal" motion has been seen before in high-speed jets of material squirted out by some black holes. The stuff in these jets is moving towards us at a slight angle and travelling at a fair fraction of the speed of light, and the effects of relativity produce a kind of optical illusion that makes the motion appear superluminal.

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".
http://www.newscientist.com/article/mg2 ... uasar.html

A microquasar is formed after a very massive star explodes, leaving behind a black hole around 10 to 20 times the mass of the sun, which then starts feeding on gas from a surviving companion star. Microquasars do emit radio waves – but none seen in our galaxy is as bright as the new source in M82. Microquasars also produce plenty of X-rays, whereas no X-rays have been seen from the mystery object. "So that's not right either", Muxlow told New Scientist.

His best guess is still that the radio source is some kind of dense object accreting surrounding material, perhaps a large black hole or a black hole in an unusual environment. Perhaps the phenomenon also happens occasionally in our galaxy, but is more common in M82 because it is a "starburst" galaxy – a cosmic cauldron where massive stars are forming and exploding at a much higher rate than in the Milky Way, creating a lot of new black holes.
