Measuring the Universe

Astronomers have figured out, among other things, how big the Universe is. Most people have no idea how they figured it out.

This video by the Royal Observatory Greenwich does a fantastical job of explaining it to mere mortals using no math but outstanding visualization. It’s so well made… you gotta watch it if you haven’t yet. Yes, even if you are one of my dear astronomer readers:

Transit of Venus

As widely reported, last week there was a transit of Venus. It’s a rare event so I wisely decided to go check it out at the Lawrence Hall of Science. Unwisely, I attempted to get there on bike – but after a one hour battle with gravity I gave up, came home, showered, and drove.

Over there, they had a bunch of telescopes properly set up with filters and pointing to the Sun. Lines were long but brisk. If you missed it, this is what it looked like:

Photo of the day #32: ISS

This is a photo from yesterday’s partial eclipse taken by Thierry Legault. In it, you can see the sun partially obscured by the moon and by none other than the International Space Station itself! Amazing timing. Click to zoom.

Lunar Eclipse

Excellent time lapse video of the lunar eclipse two nights ago. I did not see it with my own eyes, it was very cloudy in Austin.
