The idea of an expanding and accelerating universe is a very hard one to fully visualize. We try anyway because that’s how humans make sense of ideas; visualizing is our way of trying to understand.
Nothing is more satisfying than thinking we understand our place in the universe. We don’t of course. At least not yet, […]
Sometimes when I write a blog post, I think of this line spoken by Jeff Goldblum’s character in “The Big Chill”, referring to how he writes for People Magazine:
“Where I work, we only have one rule: we can’t write anything longer than the average person can read during the average crap.”Many people who read blogs, […]
These last couple of weeks have seen me writing code to ingest the images the DES camera will take when it goes online into our database.
The numbers are staggering. Each night, we’ll produce 300GB of data for a total of about 165 terabytes by the end of the survey, and that’s just the raw data […]
Here’s what a galaxy whose light has been travelling 13 billion years looks like (it’s in the white square, click on the image to see a bigger one):

What’s really cool about this image is that the light from this distant galaxy was made over 10 […]
Things that produce gravity waves.Image Credit: NASA
Well, this is an interesting way to look at gravity waves.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) has been looking for gravity waves for the past two years and scientists are beginning to pour over the data.
What they are looking for are gravity waves which manifest themselves when massive objects […]
I was trolling around Flickr today for interesting astronomy pictures and found the one below. Wow.
This is the kind of image excellent equipment gives you (OK, and lots of experience):

Taken with a Takahashi refractor and an SBIG Camera, this image rivals anything I’ve seen come out of NASA.
Excellent work.
Apparently, there is a slight […]

Changing careers to work with people who are studying the nature of dark energy has been one of the best decisions I’ve ever made. I have never been happier professionally, and I admit there is much I have to learn about exactly how we are characterizing the nature of dark energy.
The discovery that […]
Long time readers know that I find string theory irritating. Very smart people have been studying this idea for decades and have yet to say something about it that I can understand. Of course I leave open the possibility that I’m an idiot, but I know I’m not the only one scrunching up […]
[Quick note: It looks like the tech guys at b5Media have been having server issues for the past couple of days. My apologies if you couldn’t get to the blog. I’ve gotten a couple of posts written that I’ll post over the course of the day to kind of catch up. Anyhoo, […]
A few days ago, during the cool-kids camp, HubbleSite released this image:

This is a very interesting image. On the left, the bright blob in the center surrounded by rings is a galaxy and the gravitational field from that galaxy is warping the light of two more galaxies directly behind it (causing […]
