Exploring Galaxies with the Hubble Space Telescope

What is the Hubble Extreme Deep Field known for?

• Photographing the entire Milky Way

• Capturing the largest galaxy in the universe

• Providing the deepest view into the universe

• Observing the closest star to Earth

How are galaxies primarily classified?

• By their color

• By their size

• By their shape

• By their age

What is a characteristic feature of spiral galaxies?

• They contain only old stars

• They have a bar structure

• They lack a galactic core

• They are always elliptical

What distinguishes irregular galaxies from others?

• They lack a specific shape or symmetry

• They have a defined spiral pattern

• They are the largest galaxies

• They contain only dark matter

What is a defining feature of dwarf galaxies?

• They are larger than the Milky Way

• They contain more than a billion stars

• They are small with less than a billion stars

• They are always elliptical

What is unique about ring galaxies?

• They have a central bar structure

• They contain a ring of light with no spiral arms

• They are the oldest galaxies

• They are always interacting with other galaxies

What characterizes starburst galaxies?

• They have a low rate of star formation

• They are composed entirely of dark matter

• They are always irregular in shape

• They have an exceptionally high rate of star formation

What is a feature of lenticular galaxies?

• They have visible spiral arms

• They are always irregular

• They contain only young stars

• They appear circular with a bright core

What is peculiar about ultra diffuse galaxies?

• They have a high rate of star formation

• They are always interacting with other galaxies

• They are extremely bright

• They have low luminosity and vary in dark matter content

What can result from interacting galaxies?

• A decrease in star formation

• The formation of a new galaxy

• Higher rates of star formation

• A complete loss of stars
