Forget — imagine what you could see with vision! The shows what the universe looks like to NASA’s . Fermi sees light with energies about a billion times what the can see, and combines 12 years of Fermi observations. The colors represent the brightness of the , with brighter sources appearing lighter in color. The prominent stripe across the middle is the central plane of our . Most of the red and yellow dots scattered above and below the Milky Way’s plane are very , while most of those within are nearby . The background that fills the image is the from distant sources that are too dim to be detected individually. Some gamma-ray sources and topics of research — currently what they are.
