3 of the Universe’s Most Extreme Galaxies

The video explores three extreme galaxies: Dragonfly 44, UGC 12591, and ADFS-27. Dragonfly 44 is an ultra-diffuse galaxy composed almost entirely of dark matter. UGC 12591 is a fast-spinning galaxy that blends features of spiral and lenticular galaxies. ADFS-27 is a massive galaxy collision observed 12.7 billion light-years away, forming a starburst galaxy. These galaxies provide insights into galaxy formation and the role of dark matter.

What makes Dragonfly 44 unique among galaxies?

• It is the brightest galaxy known.

• It is composed almost entirely of dark matter.

• It has the most stars in the universe.

• It is the smallest galaxy discovered.

Which type of galaxy is considered a rare category that appears between spirals and ellipticals?

• Lenticular galaxies

• Elliptical galaxies

• Irregular galaxies

• Spiral galaxies

What is notable about the rotation speed of Galaxy UGC 12591?

• It rotates slower than the Milky Way.

• It does not rotate at all.

• It rotates at the same speed as the Milky Way.

• It rotates almost twice as fast as the Milky Way.

What is the significance of the galaxy pair ADFS-27?

• It is the smallest galaxy pair ever observed.

• It is a massive galaxy collision from the early universe.

• It is composed entirely of visible matter.

• It is the closest galaxy pair to Earth.

What is a characteristic of starburst galaxies like ADFS-27?

• They produce stars at a much faster rate than the Milky Way.

• They do not produce any stars.

• They are made of Starburst candies.

• They produce stars at a slower rate than the Milky Way.
