Hubble's 32nd Anniversary: An Eclectic Galaxy Grouping

The video explores the Hickson Compact Group 40, a collection of five galaxies held together by gravity and possibly dark matter. It highlights the role of dark matter in galaxy interactions and predicts a future collision forming a giant elliptical galaxy. The Hubble Space Telescope's contributions to understanding the universe, including its age and expansion, are discussed. Hubble's maintenance and continued exploration efforts are also covered.

What is the Hickson Compact Group 40 primarily composed of?

• A single giant elliptical galaxy

• Five closely packed galaxies

• A cluster of distant stars

• A nebula with active star formation

How does dark matter influence the Hickson Compact Group 40?

• It increases the brightness of the galaxies

• It forms a cloud that slows the galaxies' motion

• It repels the galaxies from each other

• It causes the galaxies to spin faster

What is expected to happen to the galaxies in the Hickson Compact Group 40 in about 1 billion years?

• They will form a giant elliptical galaxy

• They will drift apart

• They will disappear

• They will become a star cluster

What has the Hubble Space Telescope helped us understand better?

• The weather patterns on Jupiter

• The surface of Mars

• The age and expansion rate of the universe

• The composition of asteroids

How has the Hubble Space Telescope been maintained over the years?

• By remote control from Earth

• By replacing it with newer telescopes

• Through automated software updates

• Via astronaut servicing missions and technical support
