“Hope is not the conviction that something will turn out well but the certainty that something makes sense, regardless of how it turns out.” –Vaclav Havel When you take a look at the planets in our Solar System, one of the most striking features about them is that they all orbit in almost exactly the…

It’s the simple formula we all know and recognize: inner, rocky worlds closest to the Sun, an asteroid belt farther out, and then gas giant worlds out beyond them. That’s how our Solar System works, at any rate. But what about the other star systems in the Universe? We’ve finally got enough data to determine…

When you think about our world and our place in the Solar System, you very likely think about Earth, spinning on its axis, with the Moon orbiting around it, and with the entire Earth-Moon system orbiting the Sun. But did you know that all of it — the Earth spinning on its axis, the Moon revolving around…

“Studying whether there’s life on Mars or studying how the universe began, there’s something magical about pushing back the frontiers of knowledge. That’s something that is almost part of being human, and I’m certain that will continue.” –Sally Ride When Curiosity landed on the martian surface in 2012, surviving “seven minutes of terror,” it went…

“Curiosity is the essence of human existence. ‘Who are we? Where are we? Where do we come from? Where are we going?’… I don’t know. I don’t have any answers to those questions. I don’t know what’s over there around the corner. But I want to find out.” –Eugene Cernan, last human on the Moon…

“The moon was like this awesome, romantic, mysterious thing, hanging up there in the sky where you could never reach it, no matter how much you wanted to. But you’re right. Once you’re actually here, it’s just a big, dull rock.” –Futurama Oh, but the big dull rocks are fascinating in their own right. Especially, mind…

“In the year 1456 … a Comet was seen passing Retrograde between the Earth and the sun… Hence I dare venture to foretell, that it will return again in the year 1758.” –Edmond Halley When ESA’s Rosetta mission “caught” its target, Comet 67P/Churyumov-Gerasimenko in August, 2014, one of its main science goals was to watch…

“Girls blush, sometimes, because they are alive, half wishing they were dead to save the shame. The sudden blush devours them, neck and brow; They have drawn too near the fire of life, like gnats, and flare up bodily, wings and all. What then? Who’s sorry for a gnat or girl?” –Elizabeth Barrett Browning As…

“When I look at the moon I do not see a hostile, empty world. I see the radiant body where man has taken his first steps into a frontier that will never end.” –David Scott, Commander, Apollo 15 The Moon is perhaps the oldest sight known to humans and our animal ancestors here on Earth, with its…
