A second alignment plane of the solar system has been discovered
Just today somebody commented that orbits are stable. This person seems to be aware of the Milankovic cycles. Honestly, I am in awe of someone who was able to calculate orbital variations with pen and paper. We see that despite our tech we still discover fundamental new insights about our immediate space neighborhood. Another one is (for some will be) the fact that most bigger planets and even moons produce methane as a result of geological activity. On Earth, this has the potential to make energy really clean and sustainable beyond anything we ever dreamt of. And – dirt cheap at that.
