Why It Took a Decade to Launch The James Webb Space Telescope | Compilation

The James Webb Space Telescope (JWST) is a groundbreaking infrared space telescope developed by NASA. Its journey from conception to launch was fraught with challenges, including design innovations and delays. The telescope's unique features, such as its gold-coated mirrors and sunshield, enable it to observe distant galaxies and exoplanets. Despite setbacks, JWST's successful launch marks a new era in space exploration, promising insights into the universe's origins and the potential for detecting alien life.

What is the primary purpose of the Mid Infrared Instrument (MIRI) on the JWST?

• To detect distant old galaxies and newly forming stars

• To communicate with other satellites

• To observe visible light

• To measure the Earth's atmosphere

Who was responsible for creating the first telescope?

• Galileo Galilei

• Hans Lippershey

• Isaac Newton

• Johannes Kepler

What was a major limitation of early telescopes that used lenses?

• They were too small

• They were too expensive

• They bent different wavelengths of light differently

• They could not be used at night

Why is gold used in the JWST's mirror coating?

• Gold is lightweight

• Gold reflects infrared wavelengths well

• Gold is easy to polish

• Gold is inexpensive

What was one of the main challenges in designing the JWST's mirror?

• Making it out of glass

• Polishing it to work at extremely low temperatures

• Ensuring it could withstand high temperatures

• Making it small enough to fit in a rocket

What was a significant reason for the delays in the JWST's launch?

• Weather conditions

• Technical challenges and new technologies

• Lack of funding

• Political issues

What is the primary mission of the JWST?

• To monitor Earth's weather

• To study the early universe and exoplanets

• To replace the Hubble Space Telescope

• To explore the Moon

How does the JWST plan to detect signs of life on exoplanets?

• By detecting radio signals

• By capturing images of the surface

• By looking for synthesized chemicals like CFCs

• By measuring temperature changes

What phenomenon causes the light from distant stars to stretch into infrared wavelengths?

• Redshift

• Blueshift

• Doppler effect

• Gravitational lensing

What is a unique feature of the JWST's sunshield?

• It is made of glass

• It is powered by solar panels

• It is transparent

• It is the size of a tennis court
