Meet the Milky Way's Last Big Meal: The Sausage Galaxy

The video explores the Milky Way's history of consuming other galaxies, focusing on the Sausage galaxy collision that contributed to the Milky Way's bulge. It also discusses Jupiter's auroras, influenced by its moons and magnetic field, with insights from the Juno spacecraft.

What evidence suggests that the Milky Way devoured the Sausage galaxy?

• The size of the Milky Way

• The orbits and chemical makeup of certain stars

• The color of the Milky Way's halo

• The presence of black holes

What was a likely consequence of the Milky Way's collision with the Sausage galaxy?

• Formation of a new galaxy

• Disappearance of the Milky Way's halo

• Puffing up of the Milky Way's disk

• Creation of a black hole

What did the Sausage galaxy hypothetically contribute to the Milky Way?

• A new spiral arm

• A black hole

• A new set of planets

• The majority of the stars in the interstellar halo

Which spacecraft has provided new insights into Jupiter's auroras?

• Voyager

• Cassini

• Hubble

• Juno

What causes the auroral emissions on Jupiter?

• Solar flares

• Collisions with asteroids

• Jupiter's magnetic field accelerating electrons

• Volcanic eruptions on Io

Which moon of Jupiter leaves the largest auroral footprint?

• Europa

• Ganymede

• Callisto

• Io

What unique feature does Ganymede have that might affect its auroral footprint?

• It has a thick atmosphere

• It is the largest moon

• It has its own magnetic field

• It is closest to the Sun
