WFIRST observatory to have a Coronagraph Instrument
Q. What is a Coronagraph instrument?- Published on 22 Feb 16a. Blocks light of host stars
b. Enables detailed measurement of chemical composition of planetary atmosphere
c. Unveils faint light of planets orbiting around individual stars
d. All of the above
ANSWER: All of the above
The WFIRST observatory being developed by NASA will survey massive regions of the sky in near infrared light to answer basic questions about the evolution and structure of the universe. The observatory also aims to expand knowledge of planets beyond the solar system known as exoplanets. WFIRST carries a Wide Field Instrument for surveys and a CI designed to block glare of host stars and use the light of the planets orbiting around them to study the planets and chemically classify their atmosphere. Wide Field Instrument provides the telescope the ability to capture single image with depth and quality of Hubble but covering 100 times the area. It will capture the direct images of other gaseous worlds and SuperEarths
