What is a Neutron Star?

The video tutorial explains the life cycle of stars, focusing on the outcomes of supernova explosions. Stars with different masses leave behind either neutron stars or black holes. Neutron stars, unlike black holes, are observable and are known for their extreme density and gravitational effects. The video discusses the challenges of studying neutron stars due to their extreme conditions and highlights NASA's NICER mission, which aims to explore these celestial bodies further. The mission also includes a technology demonstration called sextant, which uses neutron stars for navigation in deep space.

What determines whether a star becomes a neutron star or a black hole?

• The star's original mass

• The star's temperature

• The star's age

• The star's distance from Earth

How are neutron stars different from black holes in terms of observability?

• Neutron stars are larger than black holes

• Neutron stars emit no light

• Neutron stars can be observed directly

• Neutron stars are invisible

What is a unique feature of neutron stars regarding their density?

• They are less dense than Earth

• They have the same density as the Sun

• They are the densest observable objects in the universe

• They are hollow inside

Why can't scientists reproduce the conditions of neutron stars on Earth?

• The conditions are too extreme

• Neutron stars are too small

• Neutron stars are too far away

• Earth's gravity is too strong

What is the purpose of NASA's NICER mission?

• To study neutron stars using X-ray observations

• To measure the speed of light

• To explore the surface of Mars

• To find new planets
