The Farthest Galaxy We've Ever Seen! | SciShow News

The video explores the discovery of the most distant galaxy, GN-z11, using the Hubble and Keck 1 telescopes. It explains how redshift helps measure galaxy distances and discusses the challenges in converting redshift to light years. The video also delves into early galaxy formation theories and the search for a hypothetical ninth planet in our solar system, supported by observations of exoplanet HD 106906b. These findings could provide insights into the universe's early stages and the dynamics of our solar system.

What is the significance of observing light from distant galaxies?

• It helps us measure the temperature of galaxies.

• It shows us the current state of the universe.

• It reveals the future of galaxies.

• It allows us to see galaxies as they were in the past.

What is redshift and why is it important in astronomy?

• It is the bending of light around massive objects.

• It is the process of galaxies changing color.

• It is the shrinking of light wavelengths, showing a galaxy's age.

• It is the stretching of light wavelengths, indicating a galaxy's distance.

Why is converting redshift to light years challenging?

• Because redshift is not related to distance.

• Because redshift only applies to nearby galaxies.

• Because it requires assumptions about the universe's expansion.

• Because light years are not a standard unit of measurement.

What can studying ancient galaxies tell us about the universe?

• The future of our Solar System.

• The formation and evolution of early galaxies.

• The current state of the Milky Way.

• The temperature of distant stars.

What is the proposed ninth planet in our Solar System?

• A planet orbiting another star.

• A newly discovered planet near the Sun.

• A hypothetical planet beyond Neptune.

• A planet between Mars and Jupiter.

How does the exoplanet HD 106906b relate to the ninth planet hypothesis?

• It was discovered at the same time as the ninth planet.

• It has an unusual orbit that supports the possibility of a ninth planet.

• It has a similar mass to the ninth planet.

• It is located in the same solar system.

What is unique about the orbit of HD 106906b?

• It is perfectly circular.

• It is highly elliptical and misaligned with its stars.

• It is the closest orbit to its stars.

• It is the fastest orbit in its system.
