Sounds interesting now, tell me more in-depth!

  • It can study more than 250k objects at one and collect lights from them simultaneously for 100 hours since that is the threshold required for any light to make sense out of it and deduce some results.
  • But the heat from that equipment (called MIRI) can interfere with the light collected and hence a cryocooler was built to keep MIRI below -266 degree Celsius (i.e. below - 447 degrees Fahrenheit).
  • Moreover, a 5-layer shield called sunshield made up of Kapton was built to shield the system from the external temperature of sun and moon. And then for the same reason, it had to be 1.5 million km from earth (mars is 170 million km) as compared to Hubble which is only 547 km
  • It will be located at a special location where gravitation forces allow the object to a fixed position relative to earth. It is called the Lagrangian point (L2)
  • Fun fact, it can detect the heat signatures of a bumble bee on the moon

What is next?
