# Living in Space

Living in the International Space Station (ISS). Everything in the ISS floats so it is difficult to sleep, change clothed and eat. Therefore there are fasteners which help. After the astronauts wake up, they can shower, eat,exercise and work. The food is mostly froze , dehydrated, or heat stabilized. In space the astronauts do not use their muscles a lot so the muscles become weaker. This is why exercise is needed to keep the muscles working. When an astronaut becomes injured, the medical officer will be the one to treat a patient. Each astronaut has different roles. The astronauts keep themselves busy by bringing their own entertainment such as music and books. They can also look out the window to see the beautiful view. In the ISS, the temperature is kept stable therefore they can wear anything comfortable.

# Parallax

Parallax is the view from two different lines of signt used to find the distance to the stars. To find the distance, find the distance of the base of the triangle. Determine the angle to the distant object from each end of the baseline. Then calculate the distance to the distant objetc from the baseline.

# Galaxy Type

The Messier 81 is a spiral galaxy. When I look at the galaxy there is a pinwheel shape to the galaxy. There is also a bulge in the middle where the red arms are surroundings. I am able to see red and blue colours around the galaxy.

The M32 galaxy is elliptical, a dwarf galaxy. This galaxy resembles a thick cigar. Compared to the Messier 81, the M32 has less shape and colour to it. The M32 is the largest and the oldest universe. Elliptical galaxy’s tend to be more 3D than other galaxies.

This galaxy named Coddington’s Nebula is a dwarf irregular galaxy. The Nebula does not have an exact shape or size however, they resemble some parts of the spiral and elliptical galaxy. This galaxy is small and includes dust and gas.
