The WISE (Wide Field Infrared Survey Explorer) is NASA's latest space observatory spacecraft which was (I think) successfully launched just over an hour ago. Among its possible discoveries, it is suggested via this cool video by WISE scientist Amy Mainzer :
That WISE may discover a cool star or brown dwarf nearer to our Sun than current record holder (4.2 Light years off) Proxima Centauri. Neat enough in itself - but what's more is this star could be as cold as an iceberg. (I'm guessing, BTW, that applies to the surface layers only and not the hypothetical objects core temp!)
So I just thought I'd see what other people think here :
1) Will WISE discover a red dwarf star closer than Proxima Centauri?
2) Will WISE discover a brown dwarf closer than Proxima Centauri?
3) Will WISE discover a brown dwarf closer than Proxima that's cold or colder than an iceberg?
4) Will WISE discover more just than one star / brown dwarf closer than proxima Centauri?
Or will it be as case of
5) Nup, Proxima will keep its record & WISE will fail to turn up anything closer?
Also anyone care to bet on when such discoveries may occur? (no money, well none from me anyhow, for the very simple reason that I have none. )
(Yes I like polls - as you may have noticed. )
PS. If you can't decide I have enabled multiple choice voting here. Of course, voting Proxima keeping its record is rather inconsistent with all the other options but still ... For the record my (lack of) money & hope is on all the first four objects being found - a red dwarf, a brown dwarf , more than one of each and an iceberg cold or colder brown dwarf closer in than Proxima. That'd be so cool, it'd be infrared .. not sure when but I'd guess within the next five years maybe?
