“This job is a great scientific adventure. But it’s also a great human adventure. Mankind has made giant steps forward. However, what we know is really very, very little compared to what we still have to know.” -Fabiola Gianotti On Earth, star trails inevitably appear in any long-exposure image unless you account for the rotation of the…

“When I was in high school, I was certain that being an astronaut was my goal. It was a very important time — Sally Ride was making her first flight into space and she had a real impact on me. Those ‘firsts’ kind of stick in your head and really become inspirations for you.” Karen Nyberg,…

“The slow philosophy is not about doing everything in tortoise mode. It’s less about the speed and more about investing the right amount of time and attention in the problem so you solve it.” –Carl Honore Einstein’s theories of special and general relativity tell us that there’s no Universal, preferred frame of reference. But that…

“TW Hydrae is quite special. It is the nearest known protoplanetary disc to Earth and it may closely resemble the Solar System when it was only 10 million years old.” -David Wilner For hundreds of years since the realization that Earth and the other planets orbited the Sun, humanity had only hypotheses about how planets…

“When a star goes supernova, the explosion emits enough light to overshadow an entire solar system, even a galaxy. Such explosions can set off the creation of new stars. In its own way, it was not unlike being born.” -Todd Nelson In 1604, Kepler’s supernova went off, the last Milky Way supernova visible to naked-eye…

“Every single time you make a merger, somebody is losing his identity. And saying something different is just rubbish.” -Carlos Ghosn A galaxy cluster is the largest individual bound structure in the Universe, containing anywhere from dozens to thousands of times the mass of our Milky Way. Yet as the cosmic web grows and evolves,…

“The night has a thousand eyes, and the day but one; Yet the light of the bright world dies with the dying sun.” -Francis William Bourdillon When we look for the brightest, bluest, most massive individual stars, we’re restricted to looking nearby, since it’s impossible to resolve individual stars at distances that extend much beyond…

“The truth is you can be orphaned again and again and again. The truth is, you will be. And the secret is, this will hurt less and less each time until you can’t feel a thing. Trust me on this.” -Chuck Palahniuk The planets we know of — in our own Solar System and beyond…

“True realism consists in revealing the surprising things which habit keeps covered and prevents us from seeing.” -Jean Cocteau Each time you look at a photograph of the Universe, you aren’t just seeing it as it was at a particular moment in time, but also in a particular wavelength (or set of wavelengths) of light!…

“This is in a real sense the capstone of the initial missions to explore the planets. Pluto, its moons and this part of the solar system are such mysteries that New Horizons will rewrite all of the textbooks.” -Alan Stern The New Horizons mission surprised everyone last July when it revealed Pluto to be a…
