Explanation:
OK, but why can't you combine images from Webb and Hubble?
You can, and
today's featured image shows one impressive result.
Although the recently launched
James Webb Space Telescope (Webb) has a
larger mirror than Hubble, it specializes in
infrared light
and can't see blue -- only up to about orange.
Conversely, the Hubble Space Telescope (Hubble) has a smaller mirror than Webb and can't see
as far into the infrared as Webb,
but can image not only
blue light but even
ultraviolet.
Therefore, Webb and
Hubble data can be
combined to create images across a wider variety of colors.
The featured image of four
galaxies from
Stephan's Quintet
shows Webb images as red and also includes images taken by
Japan's ground-based
Subaru telescope in
Hawaii.
Because image data for
Webb,
Hubble, and
Subaru are made freely available, anyone around
the world can process it themselves, and even create
intriguing and scientifically useful multi-observatory montages.
