the first planet

the first planet published on 1 Comment on the first planet

if i ever apply to go to mercury as an astronaut, my resume will just say ‘i lived in australia’.

i remember how crazy it was when water ice was discovered on mercury back in 2012. it’s funny how a hundred years ago many people assumed the other planets must be full of water and life just like earth, but then we developed telescopes and spacecraft and found dead barren wastelands instead, but then we looked closer and found ice and organic molecules and other signs that the planets aren’t as different from our world as we thought.

sedna: dini, look! i found it!

sedna: see that? it’s mercury, the closest planet to the sun. it’s over 700°c during the daytime over there, which is hot enough to melt lead.

sedna: but because there’s no atmosphere to keep all the heat in, it’s less than -170°c at night. there’s even water ice in some craters on the poles where there’s no sunlight.

sedna: and you thought the weather was bad here in australia!
dini: i maintain m-my position on that.
