I feel like I've been awfully glum in some of my recent posts, so perhaps it's time to look at the bright side of things. Maybe it's just because it feels like spring is right around the corner, but I've been feeling a little more hopeful lately.
One of the things I've been thinking about is what brought me to astronomy to begin with? For me, it wasn't some kind of a lifelong dream. I never gazed at the stars much as a child: living in the suburbs of large city made that difficult. In fact, I never really knew what I wanted to be when I grew up. When I was in 8th grade, I got inducted into some honor society, so the principal interviewed all us inductees and asked us what we wanted to be when we grew up. I thought for a bit, and replied, "Happy."
I was always good at math and science, so by high school I had narrowed my choices down to science. I spent most of my college years torn between physics and biology. My senior year, I took both an introductory astrophysics class and an advanced biochemistry class. One day, in my astro class, we were going over galaxy classifications and I naively asked the professor, "okay, but how do those galaxies form?" "We don't know," he said, and smiled at my bemusement.
This was something of an epiphany. The universe was filled with these enormous objects, and we didn't know how they get there. How do stars form? We don't know. How do planets form? We don't know. This was a huge change from all my physics classes up to this point. In virtually every other topic, there was an established answer, whether it was electromagnetism or quantum or relativity. In astronomy, I saw the possibility of doing unique, creative research. And you know what? To large extent, I am now doing unique and creative research.

- Motion Of Stars In Distant Galaxy
Astronomers have measured the motions of stars for the first time in a very distant galaxy, speeding around its host at twice the speed of our Sun through the Milky Way. The speeding stars may help astronomers understand how such compact galaxies form...
- Most Earth Like Worlds Have Yet To Be Born.
According to a new theoretical study, Earth came early to the party in evolving universe. When our solar system was born 4.6 billion years ago, only 8 percent of the potentially habitable planets that will ever form in the universe existed, which means 92...
- Reverse Discrimination?
This week I gave a talk about physics education that included a substantial discussion of the benefits of diversity in creating a successful university program. I was presenting in a different country, where the culture is patriarchal although respectful...
- Latent, Stereotypical Thinking
I got an e-mail from a local high school teacher that I thought I would share with you. Have you gotten one of these recently? If so, what did you decide do? Hello Mr. Schmelz, I am a teacher of Honors English at ABC High School. I write you today to...
- Astronomy: The Night Sky
No matter how far along you are in your sophistication as an amateur astronomer, there is always one fundamental moment that we all go back to. That is that very first moment that we went out where you could really see the cosmos well and you took...
