A Journey Through the Universe: Exploring with Radio Telescopes

🌌Radio telescopes enable us to explore the universe beyond what is visible to the human eye.

📡Radio galaxies, powered by supermassive black holes, emit radio waves that can be detected by radio telescopes.

🌌The GLEAM survey discovered 300,000 radio galaxies, revealing the vastness of our universe.

🕹️Radio astronomy opens new possibilities for exploring the cosmos and understanding its physical processes.

🌌Radio telescopes help us study the history of the universe, from the first stars to the present day.

What is radio astronomy?

—Radio astronomy is the study of celestial objects using radio waves emitted by galaxies, stars, and other astronomical sources.

How do radio telescopes work?

—Radio telescopes capture radio waves from space using large antennas and convert them into electrical signals for analysis.

What can we learn from radio galaxies?

—Radio galaxies provide insights into the formation and evolution of galaxies, supermassive black holes, and the cosmic web.

What is the GLEAM survey?

—The GLEAM survey is a radio astronomy project that mapped the entire southern sky, discovering thousands of radio galaxies.

Why is radio astronomy important?

—Radio astronomy allows us to study the universe in new ways, revealing its hidden phenomena and expanding our understanding of the cosmos.
