EARTH SCIENCE PICTURE OF THE DAY


“How bright and beautiful a comet is as it flies past our planet
provided it does fly past it”
ISAAC ASIMOV

Comet Hyakutake, taken by Peter Ceravolo March 17, 1996 with film. Later processed by Debra Ceravolo.

“All things originate from one another
and vanish into another
… according to time”
~ANAXIMANDER
“We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.”
Jill Tarter
“Civilization exists by geological consent …. subject to change without notice.”

– W. Durant –
