The video explains how a coronagraph reduces starlight to reveal planets by using complex patterns and deformable mirrors to correct light distortions. Advanced software further processes the data, enhancing image clarity and allowing the observation of planets in star systems similar to our own.

What is the primary function of a coronagraph in observing planets?

• To increase the brightness of stars

• To block the light from planets

• To magnify the planets

• To reduce the light from stars

How does a coronagraph create destructive interference?

• By using a magnifying lens

• By combining disks with complex patterns

• By using a single opaque disk

• By reflecting light off a single mirror

What role do deformable mirrors play in a coronagraph?

• They block all light from the star

• They enhance the brightness of planets

• They focus light onto a single point

• They correct distortions in the light beam

What is the purpose of the advanced software used in coronagraphs?

• To block light from the star

• To improve image contrast and clarity

• To change the shape of the mirrors

• To increase the size of the telescope

What is the significance of the processing done by the software in the context of planet detection?

• It makes stars appear brighter

• It allows for the detection of planets similar to Earth

• It reduces the size of the telescope

• It blocks all light from the planets
