Galaxies and the Hubble Space Telescope

What is the primary role of the Hubble Space Telescope as mentioned in the video?

• To communicate with extraterrestrial life

• To monitor weather patterns on Earth

• To provide a glimpse into the early universe

• To explore the surface of planets

Which type of galaxy is characterized by a lack of gas and dust, making new star formation unlikely?

• Spiral galaxies

• Elliptical galaxies

• Irregular galaxies

• Lenticular galaxies

What feature distinguishes spiral galaxies from elliptical galaxies?

• Flat disc with spiral arms

• Presence of a central bulge

• Old stars only

• Lack of rotation

What is a defining characteristic of irregular galaxies?

• They have a well-defined spiral structure

• They are nearly spherical

• They lack symmetry and ordered structure

• They have a central bar

How do lenticular galaxies differ from spiral galaxies?

• They are primarily composed of young stars

• They have a central bulge but no spiral arms

• They contain a lot of gas and dust

• They have spiral arms
