I wonder if that might not be preferable

At least it's a dry heat.

If you ever drop your car keys into molten iron rain, let um go man, because they are gone.

On the subject of molten iron.

What a rain of molten steel might look like

I know there's more and better "meanwhile in russia" type foundry videos. I just can't find them.

FTFA: "The brown dwarf Luhman 16B - technically a 'failed star' - is 6.5 light years away and the closest object of its type to the sun"

I find this statement really confusing. Does this mean that there are other objects, I guess planets or planet like objects closer to Luhman's sun than Luhman  is. Or does it mean that there are other Luhman like objects farther from their sun than Luhman is? Or both? Or do they mean Sol when they sat "the Sun"

What a poorly written article. .

They mean Sol. It was pretty unambiguous to me...

So this "failled star" orbits its own star, which is immaterial to everything excepting in that it provides the heat that TFA mentions, and there is nothing else like it between it and us.I have that right?

It doesn't orbit a star, per se. Luhman 16 is a binary brown dwarf system, composed of an L8 dwarf and a T1 dwarf. Neither is large enough to support an active fusion core; both are around 40 Jovian masses, which is big enough to fuse deuterium and lithium, but not hydrogen-1 (protium). Since only a small fraction of the hydrogen in these things is deuterium, the fusion activity that happens is minimal, and the deuterium is used up shortly after the dwarf gets hot enough to burn it.

But yes, Luhman 16 contains the two closest brown dwarfs to us (that we know about). One could exist closer, but it would have to be relatively small and cool (small enough to be on the threshold of being a planet rather than a brown dwarf) for us not to have detected it.

To clarify: L-class dwarfs are just hot enough (due to their gravitational contraction) to shine red in the visible spectrum. T-class dwarfs only glow in the near-infrared, like an electric stove element set to simmer. There's a third class of brown dwarfs, the Y class, that doesn't glow at all, their temperature being as low as room temperature.

For that you can touch my moobies.

Thanks a ton cthulhu_is_my_homeboy, you conveyed more useful info in your post than that entire article did.   IMO.

It's a science piece from the Daily Fail, not much was to be expected.
