Subscribers saw that SpaceX Dragon capsule video a day before I posted it on the blog, if that sort of thing interests you.

My pal Ariel Waldman is a busy, busy lady. She is the global director of Science Hack day (which is VERY cool; check it out), she makes great YouTube videos about science and space, she runs spaceprob.es, and — get this — she’s going to Antarctica on a science trip.

Oh yeah, she wrote a book called “What’s It Like In Space?” (affiliate link), too, with stories from astronauts about, well… read the title again.

I love clouds. That makes me a nebulaphile, I suppose, and I’m OK with that. I always have been, but moving to Colorado has only amplified it. We get such odd cloud formations here, so keeping an eye out on the sky is generally a good idea.
One of my favorite phenomena are iridescent clouds, where very teeny droplets of water or ice break up light into various colors. You need the light to pass through the cloud, so this usually happens near the edges of clouds where they thin out. It also happens for clouds near the Sun in the sky, so they’re really hard to photograph well.
But then Göran Strand is a really good photographer. Behold!

I know, right? So pretty. I’ve posted approximately a zillion of Göran’s photos on the blog in the past, but honestly you should just go to his site and poke around His stuff is jaw-dropping. He has a gallery where he sells prints, too. Mind you, holidays are coming…
