How Do You View a 4 GigaByte Image?

All I can say is, you’re gonna need one hell of a monitor for these images…
I was in a meeting yesterday listening to a presentation from some folks at the University of Indiana discussing issues surrounding their One Degree Imager and was fascinated by the instrument.
Sometime in 2010, a 32,000×32,000 pixel camera (that’s a billion […]

34th Carnival of Space is Up

I just came back from a carnival, that’s right, the Carnival of Space, that is ( ‘Piiiiiigs iiiiiiiiin spaaaaaaaaaace’ always goes through my head when I say that).
I particularly like this post about this picture. That’s a lot of stars, definitely puts one in one’s proverbial place, doesn’t it? Somehow, the fact that […]

Sumbitchin’ Clouds

Man, it’s cloudy in Illinois. I’ve seen the sun about twice in the two weeks I’ve been here. Today there is a nice, clear sky, so I may try and see Mars this evening.
Times like this make me miss Colorado…
I hope many of you got the opportunity to go out where you […]

Mars Opposition is Tonight

Get out your scopes, binoculars or anything with a lens in it and take it outside tonight for one of the best views of Mars you’re going to get for a while.
Right now, we are very close to Mars in our orbit:

So get out there if it’s clear […]

Next Up: Mars Opposition 2007

Well, last night’s Geminid meteor shower was a bit of a disappointment for me in chilly, cloudy Illinois. I was able to see a few meteors, around a dozen or so in the few hours I sat outside (I kept going in and out since I am in the middle of town, there wasn’t a […]

Why The Geminids are Usually the Best Meteor Shower of the Year

I just read this good New Scientist article on the Geminids and it inspired a few thoughts of my own.
Reminder: this starts tonight around 10pm in the U.S. (give or take a couple of hours, just make sure you’re out by midnight).
The Geminids are among the best meteor showers for two main reasons: […]

Five Things the Star of Bethlehem Could Have Been

Today is b5Media’s Science and Heath Channel Theme Day and this week we decided to go with a top x holiday list.
I’m picking (on) the star of Bethlehem. Every year ’round this time, we astronomy buffs get questions about the star of Bethlehem. I blame the planetaria. They insist on putting on […]

Geminids are out Tomorrow

Well, here I am in rainy Illinois (no, that’s not me in the picture at left) and if the forecast for this area holds, I’m going to be sitting underneath lots of clouds while the Geminds fly overhead.
Just a reminder, they will peak tomorrow night starting around 10:30pm or so Eastern time and it will […]

Expanding Universe and Conservation of Energy

Or lack thereof.
I’ve been getting lots of questions about my post on how conservation of energy isn’t conserved in an expanding universe. Happily, I just ran across this excellent post from Sean that may clarify things a bit more.
Does Einstein’s general relativity really say that energy is not conserved? You will be unsurprised to […]

Dark Energy and Me

The Dark Energy Survey
Man it’s cold outside. Ordinarily, I would be referring to Colorado, where the past few days have seen five inches of snow and about 20 degrees.
This time, I’m actually referring to the weather in another state: Illinois, where it’s cold, rainy and wet. As I look out of my […]
