What EHT has observed?
EHT V.S. James Webb Space Telescope (JWST)
- Observation Range:
- JWST: Close to infrared waves (μm), resolution 0.1 arcseconds (1/3600 of a degree)
- EHT: Radio waves (mm), resolution 0.000025 arcseconds
Conclusion: EHT can see 4000 times clearer than JWST.
- Manner of Operation:
- JWST: By itself, 1.5 million kilometers from Earth
- EHT: Synthesizes (using supercomputer) the data gathered from an array of observatories located worldwide; together these observatories are equivalent to a giant observatory the size of the Earth
