Constellations & Navigation using Space

Why is a star chart a useful tool?

• It is used to determine the sizes of dwarf planets and comets.

• It is used to locate stars and constellations

• It is used to determine the sizes of black holes.

• It is used to locate asteroid belts.

Scientists at NASA have developed the James Webb Telescope. According to the scientists, it will bring a new perspective to viewing the universe.

What is the importance of such telescopes?

• They help aircraft navigate.

• They help protect Earth from solar radiation.

• They help predict upcoming climatic conditions.

• They help study and explore new objects present in space.
