What I knew about space so far
What I know now
What I knew before
There is a space station in space just floating around.
The ISS was built by robots including Canada Arm, because humans arent able to build things that big in space. :robot_face:
Chris Hadfield went to the moon .
The earth is always moving.
The earth spins on its axis which causes days, and one full rotation is 24 hours which equals 1 day. It revolves around the sun which causes years. The earths rotation and revolution combined is what causes seasons. :earth_americas:
There are types of rocks , stars, and other things floating around in space.
In winter is stays darker for longer.
Lightyears is a unit used in space.
Lightyears are used to measure distances to stars and other objects outside of our solar system.
Celestial Objects
Asteroids and comets and two types of rocks in space. A comet is made out of ice, and an asteroid is not.
Stars are a type of celestial object that are formed from nebulae, which is a big cloud of dust and gas. Stars are mostly consisted of hydrogen gas. :stars:
The two most important properties of a star are colour and brightness. Brightness can Gove information about size, and colour can give information about there temperature. :star2:
Chris Hadfield did the first Canadian spacewalk in April 2001. :male-astronaut:
Telescopes are used to see stars in space from earth.
This is caused by the tilt of the earth (23.5 degrees). Its darker in the winter because of the tilt, so the area that is darker in winter is tilted away from the sun, where in summer its tilted towards.
The James Webb telescope will allow scientists to see deeper into space and allows us to gather light. The specific type of light thats being looked at is infrared light, which is a red shift of light that is super hard to pick up. The telescope is aiming to be launched on March 30 2021 and will be 21 feet tall. :telescope:
