Wright later said that whereas the spectra of WISE 1 and WISE 2 are unambiguous, the spacecraft has found many more objects that may also be brown dwarfs. Confirmation of those will await follow-up observations, which the group has proposed on the Spitzer Space Telescope. Distances to the two new brown dwarfs are not known, Wright added, but WISE should be able to turn up bundles of such objects in its 10-month mission, some of which may be closer to the solar system than Proxima Centauri, the nearest known star to the sun.
WISE Satellite Already Spots Two Brown Dwarf's
AN invisible star may be circling the Sun and causing deadly comets to bombard the Earth, scientists said yesterday. The brown dwarf - up to five times the size of Jupiter - could be to blame for mass extinctions that occur here every 26 million years. The star - nicknamed Nemesis by Nasa scientists - would be invisible as it only emits infrared light and is incredibly distant.
NASA: Exceptional object in our cosmic neighborhood - NASA Announces Televised Chandra News Conference - NASA will hold a news conference at 12:30 p.m. EST on Monday, Nov. 15, to discuss the Chandra X-ray Observatory's discovery of anexceptional object in our cosmic neighborhood. The news conference will originate from NASA Headquarters' television studio, 300 E St. SW in Washington and carried live on NASA TV.

Thanks for your diligence.
Yes, I can hardly believe that they will report about this. We shall see. I am not getting my hopes up that the announcement will be anything significant.
The 30-year-old object is a remnant of SN 1979C, a supernova in the galaxy M100 approximately 50 million light years from Earth.

Why, on the following linked site
does it quote a newspaper article written on 12 march 2012?

I was wondering how far out a cosmic neighbor could be. That's significantly farther than I imagined. Apparently, when it comes to x-ray sources that's a neighbor.

thanks for the link. I have been aware of the binary research institute for quite a while and have listened to quit a few of their radio shows. I would advise all to at least try. they have quite a bit of free listening and a good portion of it is not too bad.
thankfully there have been no fools on this thread so far. well I guess that may also depend on ones view of the fool but so far everyone has acted impecably to each other and fought and exchanged and still managed to be quite civil to each other. for this reason I thank all. I would be pleased if we could continue in the same fashion.
you changed your avatar?
peace to you all

A brown dwarf star is a star that failed to gain sufficient mass to ignite. It's not going to be larger than the sun if it's a brown dwarf. If it were to be a dead star that had previously undergone fusion, it would have either blown itself to bits or become a white dwarf. Something isn't jiving here, I don't think a second star is being observed.

Here's the problem..
We would SEE something like that. It's huge, not some little planet..It's a STAR.
Nobody can see it...
People could see it from their backyards...they don't.
There is nothing there..
