NASA have just announced that they believe they have discovered ice in Mercury's polar craters.

Don't see how that's possible. Mercury has no atmosphere.

Ice delivered by an asteroid, the crater formed shielded the ice from the sun, keeping it from melting/evaporating. Water sublimes slowly enough that it could stay there in ice form for a good while.

You would probably not enjoy the galaxy NGC 1277. Never mind that it's far - 220 million light-years away in the constellation Perseus. The problem is that at its center is a giant, giant black hole, 17 billion times as massive as our sun, so big that scientists calculate it makes up 59 percent of the mass of the galaxy's disc.

Don't want to read the whole thread. Has Rocketman been mentioned?
