The universe is an amazing place.

I was looking for Hubble pictures today and came across some neat stuff about it. These images from the Hubble telescope are amazing, especially the nebulas. Some neat facts about this solar-powered bus-sized device:

  • In order to take images of distant, faint objects, Hubble must be extremely steady and accurate. The telescope is able to lock onto a target without deviating more than 7/1000th of an arcsecond, or about the width of a human hair seen at a distance of 1 mile.
  • Hubble has no thrusters. To change pointing angles, it uses Newton’s third law by spinning its wheels in the opposite direction. It turns at about the speed of a minute hand on a clock, taking 15 minutes to turn 90 degrees.
  • Hubble has the pointing accuracy of .007 arc seconds, which is like being able to shine a laser beam on a dime 200 miles away.
  • Outside the haze of our atmosphere, Hubble can see astronomical objects with an angular size of 0.05 arc seconds, which is like seeing a pair of fireflies in Tokyo from your home in Maryland.
  • Hubble has peered back into the very distant past, to locations more than 13.4 billion light years from Earth.

The enormity is almost incomprehensible… makes me feel so small.

A new month.

So far so good – I started a batch of sauerkraut and made my wrist less hurty – something released in there when I was scooping the litter box. It’s weird how the calendar can make things feel like a new start.

Awesome veggie pizza.

We had a client here in our office today, and wanted to get pizza for lunch. Trav told us there was a special for two medium two topping pizzas – what would we like? Well, we must have missed the two topping part because as he was naming off veggies, we kept saying, “Yes, yes, yes! Sounds good. Yes!” And by the time we were done loading up our pizza, it was no longer the special and our one pizza cost more than the two mediums. Oops! It was delicious, though!!
