Wonders of the Milky Way

What are black holes in the Milky Way?

• Areas in space with high levels of radiation that emit light

• Regions in the Milky Way where stars are formed

• Large celestial bodies that emit gravitational waves

• Extremely dense regions in space where gravity is so strong that nothing, not even light, can escape.

How do black holes form in the Milky Way?

• Collision of galaxies

• Accretion of interstellar gas

• Supernova explosions

• Collapse of massive stars

What is the galactic structure of the Milky Way?

• barred spiral galaxy

• globular cluster

• irregular galaxy

• elliptical galaxy

How are stars distributed in the Milky Way?

• Stars in the Milky Way are distributed in a straight line.

• Stars in the Milky Way are distributed in a spiral pattern.

• Stars in the Milky Way are distributed randomly.

• Stars in the Milky Way are distributed in a circular pattern.

What are the different components of the Milky Way's galactic structure?

• nucleus, arms, atmosphere

• core, spiral arms, corona

• center, rings, sphere

• bulge, disk, halo

What are the spiral arms of the Milky Way?

• Norma Arm, Scutum-Centaurus Arm, Sagittarius Arm, Perseus Arm

• Carina-Sagittarius Arm

• Cygnus Arm

• Orion Arm

How many spiral arms does the Milky Way have?

• 4

• 5

• 3

• 2

What is the significance of the Milky Way's spiral arms?

• The spiral arms of the Milky Way are regions of lower density and star formation.

• The spiral arms of the Milky Way are regions of higher density and star formation.

• The spiral arms of the Milky Way are regions of dark matter concentration.

• The spiral arms of the Milky Way are regions of interstellar gas depletion.

How do stars and gas move within the Milky Way's spiral arms?

• Stars and gas move in rotating patterns around the galactic center, following elliptical orbits and experiencing compression and expansion in the spiral arms.

• Stars and gas move in a circular motion around the galactic center without any compression or expansion in the spiral arms.

• Stars and gas move in straight lines away from the galactic center.

• Stars and gas move in random directions within the spiral arms.

What is the role of the Milky Way's spiral arms in star formation?

• The Milky Way's spiral arms repel gas and dust, preventing star formation.

• The Milky Way's spiral arms have no effect on star formation.

• The Milky Way's spiral arms compress gas and dust, creating regions of higher density where new stars can form.

• The Milky Way's spiral arms cause stars to explode, inhibiting star formation.
