NASA Webb TelescopeVerified account

In case you're curious how far back #JWST will see by comparison, #JWST will see objects formed 200 million years after the Big Bang.

@NASAWebbTelescp is that with gravitational lensing or without?

@MichaelZigelman Without. Gravitational lensing might allow us to see better, but would not necessarily let us see further back in time.

@NASAWebbTelescp Where there already galexys already formed at that time? If not what are you expecting to see?

@MichaelZigelman We expect to see the first galaxies forming, based on one theoretical model. We need #JWST to test this prediction!

@NASAWebbTelescp Well I hope all construction and everything else goes as planned. Thanks a lot for answering my questions!

@MichaelZigelman Thank you! And thanks for asking. They were good questions.

@NASAWebbTelescp Most of my knowledge stems from NASA making amazing discoveries. You guys deserve all the thanks. You're all great! :)
