Exploring the Electromagnetic Spectrum with Fermi

Why is the human eye considered crucial to astronomy?

• It allows us to see the entire electromagnetic spectrum.

• It helps us observe the luminous universe of stars, planets, and galaxies.

• It is the only tool needed for modern astronomy.

• It can detect gamma rays naturally.

What makes the Fermi Gamma-Ray Telescope unique compared to ordinary telescopes?

• It uses mirrors and lenses to guide gamma rays.

• It detects gamma rays using a sensor similar to a Geiger counter.

• It can only detect radio waves.

• It is located on the surface of the Earth.

Before Fermi's launch, how many known celestial sources of high-energy photons were there?

• Ten

• Four

• Five hundred

• Fifty

What are 'Fermi bubbles'?

• Giant structures emanating from the Milky Way's center.

• Structures formed by supernova explosions.

• Clusters of newborn stars.

• Regions of low energy in the universe.

What is the main focus of Fermi's ongoing research?

• To explore the surface of planets.

• To map the entire visible universe.

• To understand the mysteries of high-energy phenomena.

• To detect low-energy radio waves.
