Question

which of the following did not detect the cosmic microwave background radiation?
hubble space telescope
cobe
wmap
penzias & wilson

Explanation:

The Hubble Space Telescope is mainly used for observing visible light, ultraviolet light, and infrared light from celestial objects such as stars, galaxies, and nebulae. It is not designed to detect Cosmic Microwave Background (CMB) radiation. CMB is a form of microwave radiation. COBE (Cosmic Background Explorer) was the first satellite to accurately measure the CMB spectrum and its anisotropies. WMAP (Wilkinson Microwave Anisotropy Probe) provided more detailed maps of the CMB. Penzias and Wilson accidentally discovered the CMB using a microwave horn antenna.
