Exploring the Milky Way and Fermi Bubbles

What is the primary characteristic of active galactic nuclei (AGNs)?

• They are always inactive.

• They contain a supermassive black hole consuming gas.

• They are smaller than quasars.

• They are found only in the Milky Way.

What unexpected discovery did astronomers make using the Fermi Gamma-ray Space Telescope?

• A new planet in the Milky Way

• A pair of high-energy gamma ray bubbles

• A black hole in the Andromeda galaxy

• A new type of star

What process is responsible for generating gamma rays in the Fermi Bubbles?

• Gravitational lensing

• Radioactive decay

• Inverse Compton Scattering

• Nuclear fusion

What is one theory for the origin of the Fermi Bubbles?

• A nearby quasar

• A large asteroid impact

• A series of supernova explosions

• A collision with another galaxy

What is the second theory for the creation of the Fermi Bubbles?

• A collision with a comet

• A nearby supernova

• A massive solar flare

• A temper tantrum from Sagittarius A*

What recent discovery was made using the MeerKAT telescope array?

• A new planet in the Milky Way

• A new galaxy

• Two bubble-shaped radio structures

• A new type of black hole

What is the main difference between the radio bubbles and the Fermi Bubbles?

• Radio bubbles are larger

• Radio bubbles are more energetic

• Radio bubbles are found in other galaxies

• Radio bubbles are younger

What is the significance of the recent increase in X-ray activity from Sagittarius A*?

• It indicates a new planet formation

• It shows a decrease in gamma rays

• It confirms the end of the Milky Way

• It suggests potential future activity
