“The cosmic game changed forever in 1992. Before then, logic told us that there had to be other planets besides the nine (if you still count poor Pluto) in our solar system, but until that year, when two astronomers detected faint, telltale radio signals in the constellation Virgo, we had no hard evidence of their…

“There is no question that climate change is happening; the only arguable point is what part humans are playing in it.” –David Attenborough If the Earth didn’t have any global warming at all, our planet’s mean temperature would be 255 K, or about -1º Fahrenheit: the mean temperature of the Antarctic continent. As it stands…

“We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.” -James Hansen Thanks to our position in space, the energy output of the Sun, and the right atmospheric conditions on Earth, we have temperatures conducive to liquid water on our planet.…

“A long time ago people believed that the world is flat and the moon is made of green cheese. Some still do, to this day. The man on the moon is looking down and laughing.” -Vera Nazarian When people make claims that are patently untrue — like the Earth is flat — perhaps your knee-jerk…

“By refocusing our space program on Mars for America’s future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it’s time for us to live and work on Mars, first on its moons and then on its surface.”…

“To explain all nature is too difficult a task for any one man or even for any one age. ‘Tis much better to do a little with certainty & leave the rest for others that come after you.” -Isaac Newton Perhaps the greatest, most successful scientific theory of the past century is Einstein’s General Relativity,…

“More days to come / new places to go I’ve got to leave / it’s time for a show Here I am / Rock you like a hurricane!” -The Scorpions On Earth, category 5 hurricanes cause devastation wherever they make landfall, bringing sustained winds, rain, destruction and — in many cases — casualties. But despite…

“Actually I think Art lies in both directions – the broad strokes, big picture but on the other hand the minute examination of the apparently mundane. Seeing the whole world in a grain of sand, that kind of thing.” -Peter Hammill When fine-and-coarse-grained sand is carried by the winds across uneven terrain, sand dunes form…

“The phenomena of nature, especially those that fall under the inspection of the astronomer, are to be viewed, not only with the usual attention to facts as they occur, but with the eye of reason and experience.” -William Herschel We typically think of Saturn as our Solar System’s ringed world, thanks to its huge, glorious…

“We are not learning to view ourselves as an advanced, evolving civilization. That is what we really must learn to do, in due course, if we were to survive. All of that will take place, in due course, and we will be able to explore solar system. We will be able to go beyond it,…
