Thanks, Hubble !

This is Sombrero Galaxy and it is in Virgo's Constellation. Maybe this is the best photo from Hubble Telescope. It's so far away... 28 million of light-years !!

Galileo on the Moon

One hammer and one falcon's feather on the moon prove that Galileo's idea was right. They fall down without any difference, they arrive to the ground at the same time. Great!

Science and Women

They are Anne Marie Paulze Pierrete and Antoine-Laurent de Lavoiseir. Maybe you know who was Lavoisier but who was she?... Do you know?... I can say only one thing, she was a very important scientist. They discovered the Conservation of the Mass on Chemical Reactions. But History remembers only his name. Why do you think this is so?
