Aimed 2,000 light-years away, this test far surpassed all expectations. 🛰
To be precise, these distant galaxies are ancient — several billions of years. But this is only a taste of Webb's capabilities, which scientists expect can see as far as"a couple hundred million years after the Big Bang," added Rigby.As the flagship successor to the Hubble Space Telescope, the James Webb Space Telescope will give astronomy wave after wave of discovery.
suspected to have the makings for life but also show the conditions of the very early universe in ways we've only imagined.created using a specialized pupil imaging lens inside the NIRCam instrument designed to take images of the primary mirror segments instead of images of the sky. This configuration is not used during scientific operations and is used strictly for engineering and alignment purposes.
"This summer, Webb will start searching for galaxies in the distant universe," says L.Y. Aaron Yung, a postdoc at NASA's Goddard Space Flight Center. In 1995, Hubble captured a spectacular image of the ancient universe, called the Hubble Deep Field, of what to the naked eye appears as one of the darkest, emptiest patches of sky.
A few years later, in the early 2000s, Hubble's Ultra-Deep Field image surpassed that accomplishment. Webb's advanced equipment — namely, — should ensure that Hubble's successor will continue that scientific exploration.
