  • Solar System: NASA extends SORCE satellite which studies the Sun's effect on the Earth's climate, similar chemical composition of Earth and Moon result of mixing between debris disk which formed the Moon and magma ocean which covered the Earth, Spitzer observations of nearby stars suggests Moon-like objects rare in other Solar Systems, Hubble observes core of Comet 17P/Holmes which is now bigger than the Sun, Mars doubles in brightness due to its polar caps now facing the Earth, evidence for a magma ocean covering surface of Mars for a long time in early Solar System.
  • Milky Way: Evidence for rocky planets forming around stars in the Pleiades Star Cluster, discovery of white dwarfs with Carbon atmospheres,
