The TESS telescope is a shiny little thinking metal tube, drinking the light of 20 million stars in our cosmic neighborhood. It launched last year on a voyage to identify planets that look like this one—a miraculous feat, if it succeeds. Among the panoply of planets found so far, there is positively no place like […]

@nattyover: I turn for comfort to “A Dying Universe: The Long Term Fate and Evolution of Astrophysical Objects” https://arxiv.org/pdf/astro-ph/9701131.pdf @nattyover is Natalie Wolchover, science writer and editor at Quanta. “A Dying Universe” is a paper I love and have loved for years. The paper’s abstract: “We consider,” it says, how planets, stars, galaxies, and the […]
The following are excerpts from a profile of Jim Peebles, who just yesterday won a Nobel Prize. Peebles is a quintessential theorist — “I spent a few days standing near telescopes getting cold,” he said, “and in the end, my attention wandered” — whose opinion of his own theories is finely balanced. The profile is […]

(Because we can.)“ Today is the autumnal equinox, the last partial day of summer and the first partial day of autumn—at least in the Northern Hemisphere. In the Southern, today is the vernal equinox, the last full […]

He’s also a big book nerd, and his love for both fiction and nonfiction are proudly on display in his own book, Earth In Human Hands: Shaping Our Planet’s Future. The book was recently featured in an ongoing series on “Resistance Reading” selected by authors and published […]
For the past two years, I have been following the voyage of OSIRIS-REx, a spacecraft headed to an asteroid called Bennu. Bennu is important for at least four reasons: Local space history may recorded in its rocks, which are about as old as the formation of the solar system. It is carbon-rich and scientists think […]
The other day at brunch, as two of my friends and I were commiserating about things varied and universal, we agreed about the sluggish pace of our brains. What an injustice, I ventured, that our sluggishness is so out of sync with the blistering pace of this summer and of 2018. “Someone was telling me […]
My boys and I have gone to the sun and back. Not literally, of course. We’ve been on the curve of the Earth the whole time. But we’ve been on a mission, 20 nights on the road traveling north toward the longest day of the year. Our trip started in Colorado near the 40th […]
