In the rarely-examined '

But 776 kelvin? That's higher than the melting point of lead. 158 atmospheres will put any pressure cooker to shame, and has a fully poisonous atmosphere of carbon dioxide (with a dash of sulphur) for good measure.
Either TF technology is more impressive than we give the eggheads credit for, or someone at the astrographic society let a drunk temp analyze my data.
