The first habitable exoplanet!!!!!l

Gliese 581d is the first planet from around the red dwarf that might be able to maintain life.It was inially judged that it would be to cold to hold life, ."However, later analysis by atmospheric experts showed that if it had liquid oceans like Earth, they would rapidly evaporate in a 'runaway greenhouse' effect similar to that which gave Venus the hot, inhospitable climate it has today."
A new posibitlity came about when a team of astrologers found out that it has the same mass a earth. Many thought that it was Earth's twin out side of the solar  system but my people thought that it did not exist. It was proven found. If it does turn out to be habitable it would have dence air and thik clouds that made it a redish twilight. Also the surface gravity is alost doubled of Earth's. It in fact is almost nothing like Earth.

Waves

In class the past few days we have been learning about waves. I think it it is interesting because before I knew next to nothing about them. I learned there are two main types of waves; Transverse and Longitudinal. I also like doing the experiments with the jump-ropes and the slinky because its easier for me to understand what is going on. I hope to do more experiments like that soon.
