Pluto and its moons hold many secrets that New Horizons discovered through Alice – its sensitive ultraviolet imaging spectrometer. Instruments have detected an atmospheric haze which could contain methane. Pluto Underground team has created a unique spacecraft designed to investigate this mystery. The Mission As New Horizons will pass Pluto this Wednesday, astronomers will finally […]

Mercury is the sole planet in our Solar System without any moons due to its small size and weak gravity; too small for supporting one, plus closeness to the Sun makes survival of such bodies impossible. Its egg-shaped orbit lasts 88 Earth days and it may approach as close as 29 million miles to the
