Pac man returns

By Space and Aliens

Saturn's moons

Scientists from the NASA Cassini mission discovered two ‘Pac-men’ on Saturn’s moons Mimas and Tethys. Dubbed Pac man because of it resemblance to the video game craze of the 1980s; the reality of these Pacmen is that they are created due to temperature variation across the surface of the moons and can be seen via thermal imagery.

The temperature variation is caused by a difference in surface texture. High energy electrons bombard one side of the moon, compacting the ice, making it slower to heat up. Oh, and when I say heat up, to put ‘heat’ into perspective, we’re talking about solar tropical temperatures of about 65 to 95 Kelvin (-208°C to -178°C).

But back to the star of this cartoon – Pacman – I just loved this game as a child and would waste my pocket money at the local games parlour (actually, it was in a fish and chip shop) trying to out smart the goggle eyed ghosts. I even bought a ‘how to win pacman’ book. I thinks that’s the closest I’ve been to being a game nerd.

Any other gamers daring to share their gaming secrets? Don’t worry, it’s a nice safe environment, here in cyber space, to share this kind of information.

shark attack

We went to the beautiful Whitsunday islands for our summer holidays this year. In preparation for our 10 day sailing trip I made sure we were well equipped with plenty of water toys. I bought new floaty rings so we could laze around in the water and soak up the sun’s rays.

This cartoon came to mind when our snorkelling expedition team came back to announce they had seen a reef shark (harmless, in case you were wondering). But the idea of what it must look like to fish looking up instead of us snorkelers looking down was an interesting concept.
