I haven’t got much on my mind today that I want to think about so I distract myself with pictures. This one, as science pictures often do, conflates beauty and truth and let me repeat, beauty. It’s a result of letting the Hubble Space Telescope take repeated pictures of a single cluster of galaxies. Clusters […]
As of yesterday, May 20, LWON has been alive for five years. LWON is a little surprised at this and pretty pleased with itself. In celebration, two of our brilliant alumni wrote guest posts listing the Top Five Things They Wanted to List the Top Five Of. Today, Five People of LWON announce the best […]
The Hubble Space Telescope was launched aboard the aptly named Space Shuttle Discovery, 25 years ago this month. This past week (past month, past year) there have been gobs of events to mark the occasion: special talks, videos, a re-released IMAX movie, panel discussions, banquets, art exhibits, and a video contest. There was even an […]
Last month DC Science Comedy invited LWON’s own Mr. Cosmology to participate in one of the group’s Science Comedy Nights. Mr. Cosmology accepted. Empirical evidence follows.
During a total eclipse of the sun, the landscape darkens. But you knew that. What you might not know—what I didn’t know, anyway, when I observed a total solar eclipse on August 11, 1999—is that the experience comes with a lot of other sensory overload. I found myself thinking about that total eclipse while reading about the one […]
The Hubble Fellows are — forgive me — young stars: young PhD astronomers granted the money to go to whatever astronomy-doing place they want to go to and do whatever astronomy they want to do. And once a year, the Hubble Fellows give public talks about what they’re up to, so any astronomy writer with […]
Dear LWON readers, I’d like to ask you a question. Twice recently I’ve written about properties of black holes that blow my mind. In each instance, my inspiration was a detail from a movie. First was Interstellar. The great gravitational grip of the black hole in that movie, as is the case for all black holes, distorts […]
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 us to imagine that the astronaut is wearing a watch, and that […]
