Cosmic inflation one more time—well, two

Reader Sergio called this comic to my attention (via  Twi**er: @JenLucPiquant and @phdcomics), which gives a good explanation of the meaning of the recent evidence for cosmic inflation.  Maybe you understand those scientific findings by now, but just in case you didn’t read this, from Jon Kaufman and Jorge Cham at PhD Comics (Kaufman was a […]

BICEP, gravitational waves et al.

Reader Justin sent a link to this animated video by MinutePhysics that tries to explain what the BICEP project really revealed about the Big Bang (I say “tries” because I’m not a physicist). Do note, though, that Official Website Physicist™ Sean Carroll was an advisor on the science, so it must be right!. One thing […]

Neil deGrasse Tyson identifies the greatest physicist of all time—in slow motion

I don’t know why I—or reader Gregory, who sent the link to me—find this video so funny, but I suspect it’s because it makes Tyson sound like he’s been smoking wacky tobacky.  What the astonomer says is right on (he’s describing his hero Newton), but the slowing down—2/3 speed, I think—makes one think that as […]

The new Cosmos, and Neil deGrasse Tyson on science vs. religion

You might not have known that Carl Sagan’s famous television series, “Cosmos: a Personal Voyage” (13 episodes, first aired in 1980) was, at least according to Wikipedia, “the most widely watched series in the history of American public television until The Civil War (1990). As of 2009, it was still the most widely watched PBS […]

“Calm down, Lovell”: Earthrise from Apollo 8

This clip, just posted on December 23, is one of the most stirring videos ever taken on a manned space mission. YouTube gives details and refers you to other videos and sources: NASA has produced a remarkable new video replay of the moment on December 24, 1968, when the astronauts on the Apollo 8 mission […]

Best space photos of 2013

Head over to Slate and have a look at Phil Plait’s selection of “The best astronomy and space pictures of 2013“. I’ll show you just three, but believe me, you’ll want to see them all. And most of the photos are available in very resolution so you can use them as wallpaper on your computer. […]

Earth from the ISS

A lovely time-lapse video from the International Space Station, taken with cameras inside and out.  The film speeds up as the video proceeds. TRIGGER WARNING: Grandiose music.

A Vatican astronomer explains why he sees God through the telescope

Reader Grania sent me a piece from the Catholic News Agency called “Vatican astronomer: science opens the door to dialogue.”  Of course with a title like that the article is bound to be dire, and Grania added a note: “The cognitive dissonance is strong in this one.” But that’s not completely accurate, for cognitive dissonance […]

Reader’s eclipse photos, one with cat

Reader “gravelinspector” travels the world as a geologist, working (I gather) on oil rigs. Right now he’s on a ship in the Gulf of Guinea, and has a post on his website, Rock Sniffer’s Scribbles, about watching and photographing the eclipse.  Here’s one of the pictures (click to enlarge): Reader Sara sent me a photo […]

Eclipse totality at 14:25 Greenwich time: watch live!

Be sure to start watching the live video posted below (i.e. in the post right before this one) SOON: totality will be at about !4:25 Greenwich time in Kenya, or 9:25 a.m. Eastern time in the U.S.  The Moon has already started nibbling at the Sun, so if I were you I’d start watching at […]
