[Deep Star Map 2020] 5 00:00:14,514 --> 00:00:19,119 Infrared light can travel through that material ...

[Hubble infrared image] 7 00:00:24,691 --> 00:00:30,163 Infrared light has a longer wavelength than visible, 8 00:00:30,163 --> 00:00:35,635 so it’s less likely to be scattered or absorbed by small particles. 9 00:00:37,203 --> 00:00:41,441 The far side of the Milky Way remains largely unknown. 10 00:00:42,409 --> 00:00:45,211 Future infrared telescopes with greater sensitivity will help 11 00:00:45,211 --> 00:00:47,480 astronomers map that region 12 00:00:48,648 --> 00:00:53,019 by seeing deeper and with more detail than ever before.
