Hi, everyone. I found an amazing article on the Internet.This is some new evidences about Mercury.
According to this story, NASA's MESSENGER made its second close-approach flyby of Mercury in October 2008.The spacecraft was first time to visit the diminutive(small) planet since Mariner 10 spacecraft's sojourn(stay) in 1970s.Then NASA's MESSENGER discovered a giant crater and evidence of ancient volcanoes, which no one may has seen.The giant crater's length is as almost same as the distance between Washington, D.C, and Boston.Can you imagine how long this distance is? Washington, D.C is on the west coast, on the other hand, Boston is on the opposite side!There is "the other United States of America" on Mercury. That sounds nice, doesn't it?
Next, about volucanoes, NASA's MESSENGER discovered there was volcanism(volcanic activity) to make huge crust(a thin hard dry layer on the surface of something) on Mercury.One of reseachers said "Volcanism was a really important process on Mercury, which is pretty exciting because before MESSENGER's flybys of Mercury we were really not even sure that volcanism existed on Mercury,"I also was excited because of some new clues of Mercury. Even though only a few people(human beings) can have been to planets by spaceship.... Before NASA's MESSENGER went to Mercury in this investigation, scientists had thought that Mercury was very similar to Earth's moon composition for a long time.However, the surface of mercury is suppose to be more similar to that of Mars than of the Moon now. Mercury is "a member of Mars' family"! :D
This article lasts but....(I'm sleeping with typing! omg). If you're interested in Mercury and need more its information, please click link on the bottom of this article.
Well, I often view some tiny stars from my small window. Especially, I like the sky in summer. There are some reasons why I prefer summer sky to winter one.First, summer have less rainy and cloudy days than winter so that we have a lot of oppotunities to view stars clearly. Secondly, I don't like cold much. It's hard for me to go out at late night in winter.Finally, Altair(is called Hikoboshi in japanese) and Vega(is called Orihime in japanese) can see each other again on July 7. They have ONLY ONE chance per annum(every year)! Because of those reasons, I like summer sky.
Anyway, which season is the best to view stars, summer or winter? What do you think about it? Please tell me your opinion. :)

That's interesting! Boston and DC aren't really very far apart, though. Still, it is bigger than volcanoes on Earth. I think Mercury is too hot for us to live on. If it didn't rotate, maybe people could live on the dark side, but it rotates. :-(
I like the Full Moon indicator on your site today!
I'm sorry for late to reply. When I was a 4 or 5 year-old child, I misunderstoond about Mercury.(I thought Mercury was too cold to live for us because it was called 水星/sui-sei in Japanese, and I believed it consisted of cold water.) However, Mercury is too hot for us, right? Maybe Mercury won't change better for humans unless we adapt its environment. : (
