The Milky Way has thick bands of gas and dust
which block our view of what’s behind. [Deep Star Map 2020]
Infrared light can travel through that material ... [Hubble Space Telescope visible-light image]

Infrared light has a longer wavelength than visible,
so it’s less likely to be scattered or absorbed by small particles.
The far side of the Milky Way remains largely unknown.
Future infrared telescopes with greater sensitivity will help
astronomers map that region
by seeing deeper and with more detail than ever before.
