Which observational technique is indispensable for viewing $ ext{Sgr B2}$ through obscuring interstellar dust?

Answer

Infrared astronomy

Observing star formation deep within the Galactic Center, where $ ext{Sagittarius B2}$ resides, is severely hindered by thick blankets of interstellar dust that effectively obscure visible light from Earth. To penetrate these obscuring clouds, astronomers must rely on advanced infrared astronomy. Instruments capable of observing the infrared spectrum can detect the heat signatures emitted by warm dust grains and light from newly formed stars that has been redshifted beyond the visible range, making infrared light the crucial medium for revealing the ongoing collapse and stellar processes occurring within $ ext{Sgr B2}$.
