Hooray for Astromice!

The video discusses two main topics: the effects of space on mice and the discovery of a highly luminous galaxy. In the first part, researchers studied mice that lived in space and found they had thinner skin and more hair growth. This experiment, published in the journal Microgravity, highlights the need for further research on the effects of space on living organisms. The second part covers the discovery of the most luminous galaxy, detected by the WISE Space Telescope. This galaxy, part of a class called Extremely Luminous Infrared Galaxies, challenges current understanding due to its size and age. Scientists are eager to study more such galaxies to better understand their formation and characteristics.

What unexpected effects did weightlessness have on the mice sent to space in 2009?

• Thicker skin and less hair growth

• Thicker skin and more hair growth

• Thinner skin and more hair growth

• No change in skin or hair

Why is the study of the Astro mice considered limited?

• The mice were too young

• The mice were not fed properly

• The experiment was too short

• The sample size was too small

What was the main difference observed between the space mice and the Earthbound mice?

• Space mice had less hair growth

• Earthbound mice had thinner skin

• Space mice had more hair growth

• Earthbound mice had more hair growth

What is the significance of the newly discovered galaxy?

• It is the oldest galaxy discovered

• It is the most luminous galaxy known

• It is the smallest galaxy observed

• It is the closest galaxy to Earth

What challenge do scientists face in understanding the formation of extremely luminous galaxies?

• They formed too quickly after the universe began

• They are too far away to study

• Their light is blocked by interstellar dust

• They are too small to observe
