Question

galaxies and technology

1. which galaxy are we a part of? the milky way
2. what are some different shapes of galaxies? what shape is our galaxy? spiral, elliptical, and irregular.
3. are galaxies expanding outward or shrinking inward? how do we know?expanding outward. we know because of redshift
4. where are the hubble and james webb telescopes located? deep in space.

Explanation:

1. Earth is part of the Milky - way galaxy.
2. Galaxies can be spiral, elliptical, or irregular in shape, and the Milky - way is a spiral galaxy.
3. Galaxies are expanding outward as evidenced by redshift, which indicates that light from distant galaxies is shifted towards the red - end of the spectrum as the source moves away from us.
4. The Hubble and James Webb telescopes are located in deep space for better astronomical observations away from Earth's atmospheric interference.

Answer:

1. The milky way
2. Spiral, Elliptical, and irregular; Spiral
3. Expanding outward; Because of redshift
4. Deep in space
