“Our existence in this place, this microscopic corner of the cosmos, is fleeting. With utter disregard for our wants and needs, nature plays out its grand acts on scales of space and time that are truly hard to grasp. Perhaps all we can look to for real solace is our endless capacity to ask questions…

“To consider the Earth as the only populated world in infinite space is as absurd as to assert that in an entire field sown with millet, only one grain will grow.” -Metrodorus of Chios Later tonight, the European Southern Observatory is expected to make an announcement, and the smart money is on the discovery of…

“For something to collapse, not all systems have to shut down. In most cases, just one system is enough.” -Robert Kiyosaki Do supermassive black holes form from the merger and growth of many smaller black holes, falling towards a cluster/galactic center where they find one another and grow into a behemoth? Or is there a…

“He who would search for pearls must dive below.” -John Dryden If you want to know what types of stars are found all throughout a galaxy, looking at our own simply won’t do: too much of it is obscured by the plane and our position within it. But there’s an even more impressive galaxy —…

“…innumerable stars, thousands of double and multiple systems, clusters in one blaze with their tens of thousands of stars, and the nebulae amazing us by the strangeness of their forms and the incomprehensibility of their nature, till at last, from the limit of our senses, even these thin and airy phantoms vanish in the distance.”…

“Dwell on the beauty of life. Watch the stars, and see yourself running with them.” –Marcus Aurelius Let there be light! You’d think that would be enough: that you form stars in the Universe, you see those stars in the Universe, and that tells you about what’s out there. If only it were that simple.…

“Black holes can bang against space-time as mallets on a drum and have a very characteristic song.” -Janna Levin If you had told an astrophysicist five years ago that binary black holes were common, that would’ve been news, but not surprising. If you had told them that ~30 solar masses was a good estimate for…

“Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.” -Adam Riess Just thirty years ago, scientists argued over the value of the Hubble…

“The bedrock nature of space and time and the unification of cosmos and quantum are surely among science’s great ‘open frontiers.’ These are parts of the intellectual map where we’re still groping for the truth – where, in the fashion of ancient cartographers, we must still inscribe ‘here be dragons.’” -Martin Rees Inside the nuclear…

“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.…
