Red Nugget Galaxies The Universe's Ultimate Survivors

The video explores the dynamic universe, focusing on red nuggets, ancient galaxies that have survived cosmic evolution. It explains the differences between spiral and elliptical galaxies and how red nuggets, discovered by the Hubble Space Telescope, are massive yet compact. These galaxies are remnants of the first elliptical galaxies and have avoided collisions for billions of years. The video discusses how supermassive black holes in red nuggets prevent new star formation, a process called quenching. This understanding helps unravel the mysteries of galaxy formation and evolution.

What are the two main types of galaxies recognized by astronomers?

• Dwarf and Giant

• Spiral and Elliptical

• Elliptical and Irregular

• Spiral and Irregular

What is a notable feature of red nuggets?

• They are full of young, hot stars.

• They are larger than spiral galaxies.

• They have avoided collisions for billions of years.

• They are primarily found in the Milky Way.

Why are red nuggets considered 'dead' galaxies?

• They are not visible from Earth.

• They are only found in distant galaxies.

• They have stopped forming new stars.

• They have no stars at all.

What role do supermassive black holes play in red nuggets?

• They make the galaxy more visible.

• They create new stars.

• They increase the galaxy's temperature.

• They prevent the formation of new stars.

What process is responsible for stopping star formation in red nuggets?

• Cooling

• Collapsing

• Heating

• Quenching
