HD189733b is a Jupiter-sized planet orbiting so close to its host star that it's tidally locked, meaning the same side is always facing the star. This makes the near side scorching hot and the far side freezing cold. It also causes huge convectional winds to blow from the hot side to the cold side.

Spectroscopy of the planet has shown a lot of silicates and nitrites in the atmosphere of the planet, which has led scientists to believe that the ~20km/s winds blowing on the planet carry 1300ºK rains of molten glass with them. Metal as fuck.

That sounds awesome, I didn't know if such a thing was physically possible.


On a similar note, I love the sound of this planet from Halo: Broken Circle.

Spoiler

The Planet of Blue and Red is a planet tidally locked between two close stars in a binary system, one a red giant, the other a blue star. The planet doesn't have a day/night cycle and doesn't rotate, but the light shined on it by both stars makes one side of the planet blue and one side red, with the middle a deep purple where the light mixes.

That would be amazing to see.

PSR J1748-2446 is the fastest spinning object known. It's a neutron star that's literally harder than diamonds. Its matter is packed so tightly into a sphere ~30km wide, that it can withstand its fucking ridiculous rotation speed of 716 rotations per second. Proportionately that's like our Earth spinning around over twice per second instead of once per 24 hours. It spins faster than any powertool in existence.

There's no gravity in space

This is incorrect.

If there's gravity in space then why do astronauts float

The OCD in me forces me to do this, regardless if this is a troll or not.

Space has gravity; if left in space long enough, astronauts would eventually fly into the nearest planet, or the sun, depending on which was nearest. Astronauts float because there is a lack of a strong force pulling them- Earth's gravity in atmosphere is -9.81ms^-2 which means that something must be accelerating at least 9.81ms^-2 in the opposite direction to fly; in space, this force is considerably weaker, to the point where a simple action has a faster acceleration and thus gravity of Earth is overcome easier.

If two people were left in space for long enough, they would slowly drift closer together. I mean, we say that Luna orbits Earth, but in reality, they both orbit each other. Luna actually drags on Earth and slows our rotation down, otherwie our day would be about 8 hours long.

Neutron stars are amazing.

Yeah, they really baffle me at times.

They're like, the little brothers of black holes, or the tagalong kid that is desperately truing to copy the cool crowd but ends up sticking out even more. It's weird, I think, that the densest object in the universe emits no light at all yet the second densest is the brightest object in the universe.

They really straddle on the lines of a black hole. A thing that amazes me about them is starquakes. If a starquake occurred near our solar system it could very well cause a mass extinction.
