For a brief period of my life, the Hubble Space Telescope would shoot me an email with a link about once every two weeks. Then I would click and wait. Then hundreds of thousands of stars would spill across my monitor, lighting up cells in my eyes with photons from a screen from a file […]

Cosmology is timeless, perhaps literally—as this post argued on January 23, 2015. In the 1992 documentary A Brief History of Time, Stephen Hawking describes what we would see if we were observing an astronaut nearing a black hole’s event horizon—the barrier beyond which gravitation is so great that not even light can escape. He invites […]
On October 25, 2010, LWON welcomed a new occasional feature, “Ask Mr. Cosmology,” which invites readers to contribute to a mailbag full of questions about…The Wonders of the Universe! This entry comes from March 26, 2012. Q: Can neutrinos travel faster than light? Mr. Cosmology: Depends what you mean by “light.” Light, as in light rail? Yes. Light, […]
“There is an aspect to this story that is weirder than you can imagine.” That sentence was e-mailed to me by a geologist, Jan Kramers, at the University of Johannesburg in the waning days of 2017. I had e-mailed him about a paper of his in Geochimica et Cosmochmica Acta. The title of the paper […]

*Now with UPDATES, below: Betelgeuse (pronounced Beetlejuice) is a star, the red one on the left shoulder of Orion. You’ve seen it. One of the whole points of stars is that you can just look up and count on seeing them. The earth turns underneath them so it’s true that depending on time and geography, […]
The other night we were supposed to see a meteor shower with fireballs. That’s what they predicted, fireballs. My gal and I went out on the deck in the late fall chill, dropped a single sleeping pad, covered ourselves in a blanket, and stared up at a midnight quarter moon. The Taurid meteor shower and […]
