Exploring the Mysteries of Sagittarius A* and Black Holes

What is the significance of the star S2 in relation to Sagittarius A*?

• It is the largest star in the galaxy.

• It provides insights into the properties of the supermassive black hole.

• It is the fastest star in the universe.

• It is the only star visible from Earth.

What is the speed of the star S2 as it approaches Sagittarius A*?

• 10 million miles an hour

• 20 million miles an hour

• 17 million miles an hour

• 5 million miles an hour

What causes the flares detected around Sagittarius A*?

• Explosions within the black hole.

• Magnetic storms in the accretion disc.

• Reflections from nearby planets.

• Collisions with other stars.

What is the role of the accretion disc in the flares observed?

• It cools down the flares.

• It absorbs the flares.

• It creates the flares through magnetic storms.

• It deflects the flares away from Earth.

Why is Earth not threatened by the flares from Sagittarius A*?

• The distance of 26,000 light years keeps us safe.

• Earth's atmosphere blocks the flares.

• The flares are directed away from Earth.

• The flares are too weak to reach Earth.

What new discovery about the center of the Milky Way is mentioned?

• A swarm of smaller black holes around the supermassive black hole.

• A new type of star formation.

• A massive asteroid belt.

• A new planet orbiting Sagittarius A*.

What is the potential danger of the smaller black holes around Sagittarius A*?

• They could collide with Earth.

• They might merge with Sagittarius A*.

• They could be more dangerous than the supermassive black hole.

• They might block light from reaching Earth.

How are stellar mass black holes typically detected?

• By capturing images of them directly.

• By detecting X-rays emitted as they consume a companion star.

• By measuring their magnetic fields.

• By observing their gravitational pull on nearby stars.

What makes detecting stellar mass black holes challenging?

• They move too quickly.

• They emit no light.

• They are too far away.

• They are only tens of miles wide.

What type of light helps in detecting X-ray binaries?

• Visible light

• Ultraviolet light

• Infrared light

• X-rays
