Strange Alien World Made of "Hot Ice" 216
David Shiga writes "The smallest planet ever seen passing in front of its parent star is a strange world of scorching hot ice, astronomers say. The 22-Earth-mass planet has been known since 2004, but recent observations of it passing in front of its parent star have allowed them to learn much more about it. It appears to be made mostly of water, but not in liquid form. The planet orbits so close to its parent star that its surface is a broiling 300 C, keeping any water there in vapor form. Beneath the atmosphere, the water is even hotter, but is at such high pressure because of the planet's large mass that it stays in a solid, "hot ice" form."

Ice/Solid water as we know it under 1 atmosphere is formed at 0C/32F...
Let's say that under 300 atmospheres, Ice/solid water can be formed at 100C/212F
Why can't we have have Ice/Solid water at 30C/86F under atmospheres where is somewhere between 1 and 300? assuming the 300 hypothesis for solid at 100C/212F?
That would allow touching it... assuming the pressure isn't too much... or maybe, that would happen if we suddently release the pressure? from 30

And people wonder why I hated school.
Most people think the problem is ignorant teachers. This is only part of the problem. All teachers will be ignorant to some degree, just like every other person on the planet. No one can know everything.
The problem is the teachers that are ignorant, but convince themselves that they know more than the students in every case. They usually do this because the student is in class to learn, and they are in class to teach, therefore they believe the student must know less than them. Though this is almost always the case, they forget that it's actually quite common for some students to know more than them about some individual aspects of the subject matter.
You knew more than the teacher. He didn't believe you. This is not bad. Teachers can't take on faith every nut-job idea put forth from every know-it-all student. But all he had to do was say, "that's a very interesting idea. I'd love to read more about it if you can find some material on the subject." You're happy, because the teacher isn't treating you like you can't possibly know anything. He's happy, because it shuts you up about, "some wild idea." The school system is happy, because when you do show up with a source it might improve the curriculum (not likely in elementary school, but maybe in high school). And finally your parents and your educational agenda should be happy because looking for the source is likely to be a great learning opportunity.
"You're wrong," is a bad policy. "We're open to new ideas if you can show that they work," is almost always better.

Of the fourteen types of water ice, only one (Ice Ih, which is also the form that is commonly found on Earth, though Ice Ic can occasionally be found in the upper atmosphere) is less dense than the liquid form. The others form at various temperatures and pressures, and are, in that their density is greater than liquid water, more normal than "common" ice.

The pressure will not prevent the ice from forming a crystal structure (it will, in fact, cause the formation of such a structure), but that structure will be more dense than liquid water.

A very shallow hollow will have a 7.5cm radius, a figure skate about 4-5cm, a normal hockey hollow is closer to 2.5cm, and a suicidally deep hollow has a 1cm radius (But its all a matter of personal preference,

But the high pressures in the planet's interior would compress the water so much that it would stay solid even at hundreds of degrees Celsius - the expected temperatures inside the planet. There are a variety of exotic 'hot ice' states possible in such conditions, with names like 'Ice VII' and 'Ice X'.

In fact, there are two types of ice that occur naturally on this planet, traditional hexagonal ice (Ice Ih) and ice with a cubic lattice (Ice Ic (I'll avoid the too-obvious "Ice Ic, baby" joke, here. You're welcome)).
According to that Wikipedia page, there are 14 different forms of ice which occur at varying temperatures and pressures. "Common" ice, Ice Ih, is, in fact, the odd one out in some respects - for example, it's the only one that is less dense than liquid water.
