TED-Ed: Something weird is happening in our galaxy | Ashkbiz Danehkar

The video explores the discovery of the Fermi and Erosita Bubbles in the Milky Way, which emit gamma rays and X-rays, respectively. These structures suggest a powerful event occurred less than 3 million years ago. Two main theories propose that the bubbles were formed by either a burst of star formation or an outburst from the supermassive black hole, Sagittarius A*. Scientists use simulations to study these phenomena, and future research may reveal more about our galaxy's dynamic nature.

What are the Fermi Bubbles primarily composed of?

• Streams of high energy particles

• Cosmic dust

• Dark matter

• Neutrinos

What is unique about the Erosita bubbles compared to the Fermi Bubbles?

• They are smaller and emit gamma rays

• They are larger and emit soft X-rays

• They are invisible to telescopes

• They are the same size and emit radio waves

Which event is theorized to have occurred less than 3 million years ago?

• The formation of the Milky Way

• The Big Bang

• The event that created the bubbles

• The extinction of dinosaurs

What is one theory about the origin of the bubbles?

• A nearby supernova explosion

• A collision with another galaxy

• A comet impact

• A recent massive burst of star formation

What is Sagittarius A*?

• A distant galaxy

• A type of star

• A newly discovered planet

• A supermassive black hole at the center of the Milky Way

What do hydrodynamic numerical simulations help scientists explore?

• The surface of Mars

• The structure of DNA

• The behavior of ocean currents

• The formation of galactic bubbles

What external factor might influence the unique features of the bubbles?

• Solar flares

• Cosmic microwave background radiation

• Circumgalactic medium winds

• Asteroid impacts
