IBEX Map of ENAs at 0.9 to 1.5 KeV

First IBEX map of the heliosphere showing the distribution of energetic neutral atoms (ENAs) across the entire sky in the range of 0.9 to 1.5 kiloelectron volts(KeV); an unexpected swath of higher numbers of energetic neutral atoms, called the "ribbon", was detected. The ribbon is highly defined in this image IBEX simultaneously makes a total of fourteen maps at different energies. Credit: SwRI
