TIL That the obesity rates in american states, are inversely correspond to the cost of living in each state. This is true for almost every state, with the exception of Idaho, Florida, Virginia, Wisconsin, and Utah; all of which are almost average in both obesity and cost of living.

TIL what "redshift" is. BBC explains redshift as light from more distant objects showing up on earth more red than when it left its source. This is because of the Doppler Effect which acts to stretch or compress waves of moving objects. An example of this is an approaching emergency vehicle siren. As it is getting closer, it sounds higher pitched; as it is getting farther, it sounds lower pitched. In light, approaching objects appear more blue, and receding objects appear more red. The expansion of the Universe is accelerating, so in general, more distant objects are moving away from us (and each other, and everything else) more quickly than nearer ones.

TIL That there are more than 800 known exoplanets, a rocky planet with an atmosphere circling a Sun-like star in the habitable zone.
