Citizen Sky: A different type of citizen science

Citizen Sky Logo

Hi, all. Been a long time! I’m starting my fourth year in grad school and beginning dissertation work. The end is within sight, after which I hope to return to some level of activity. I’m using what few brain cells are left to think up some new, crazy stuff. But until that day eventually comes, I wanted to let you know about this other, crazy new project I’ve begun at my work: Citizen Sky.

This is not your average citizen science project. We are not asking simply for data. We also want to help YOU analyze the data and to help YOU publish YOUR results in professional journals! The idea is that citizen scientists get to experience the entire scientific process, not just one stage.

To help, we are developing tutorials, java-based analysis software with slick GUIs, building online collaborative tools, etc. We are also holding two public workshops. The first is this August at the Adler Planetarium in Chicago. That one is focused on data collection and E/PO. The second will be at the California Academies of Science in San Francisco in spring, 2010. That one will be focused on analysis and paper writing. Travel grants are available for each.

Our scientific target is epsilon Aurigae, a VERY bright star that undergoes an eclipse about every 27 years. No one understands the eclipse and there are some neat theories, include one that involves swallowing planets. The system is too bright for the vast majority of professional (and even amateur) telescopes, so we are recruiting the public to monitor the 1-2 year eclipse. Hence the citizen, in citizen science.

This is a big project. We needed the National Science Foundation to fund a grant proposal so we could do it all. The proposal itself took months for me to write, with help from a small army of collaborators. Now the NSF is going to fund us to run this project for 3 years and then, hopefully, expand into other citizen science projects. But the core is this: we want your help as real scientists, more than just data collectors (although you can stick with that if you want).

If interested, register for an account at Citizen Sky. Lots of new announcements will be posted there soon, including the opening of public forums similar to the old ones we had here once upon a time. :)

Interview: Evalyn Gates

Evalyn Gates

Doug and I had the pleasure of doing an interview with Dr. Evalyn Gates, Assistant Director of the Kavli Institute for Cosmological Physics. She studies white dwarfs (dwarves?), dark matter, cosmic strings, black holes and she recently wrote a book on gravitational lensing, Einstein’s Telescope: The Hunt for Dark Matter and Dark Energy in the Universe.

First exoplanet discovered with astrometry

By Michael on May 28, 2009 at 11:03 pm | In Blog Posts | No Comments

VB 10 system compared to earth/sun. Image: NASA/JPL-Caltech
Astrometry is the process of measuring positions on the 2-D projection of the sky through imaging. So you take a picture of the sky, identify all of the stars against a known star catalog and then determine the position of some object(s) relative to that catalog. Pre-telescope astronomy was based almost solely on (visual) astrometry.

Universe Today reports that this technique was successful in finding a planet orbiting another star. They measured the star wobbling back and forth across their images over a 12-year time period. The star is 20 light years away, which is pretty close in astronomical terms, but it is also small, cool and dim, compared to the sun.

So that’s cool. That makes for at least 2 good planet-finding techniques using only imaging, something you can do from your backyard.

Nice tribute

Olin Eggen
John Hearnshaw, as part of Cosmic Diary, has written a very nice article: Recollections of three great photometrists: Whitford, Eggen and Cousins. As a student and practitioner of modern astronomical photometry, it is very interesting to read up on my predecessors.

I, too, have recollections of great photometrists, having spent time with Dr. Arne Henden and, more recently, Dr. Arlo Landolt. It is a strange science that has given us a great deal of insight into our universe and stars in particular.

Here is video of some of the people who worked on the mission to upgrade and repair Hubble as they watch it released from the space shuttle.

Really cool Galileo telescope for $15

By Michael on May 21, 2009 at 4:14 pm | In Blog Posts | No Comments

Galileoscope

As you know, it is the International Year of Astronomy (IYA) as well as the 400th anniversary of the astronomical telescope. There is a very cool telescope that is part of these celebrations, the Galileoscope, and it is only $15 and takes just a few minutes to assemble.

If you are an educator, troop leader or other person in front of young people, you can order the scopes in bulk and receive a discount. Or, if you are a generous sort, you could buy some for your school, church or club. If you order > 99 they cost only $12.50 each!

This is a great project. None of us are doing this for the money. This is not a commercial. This is a great learning experience just waiting to happen and/or just a cool little toy to own.

Buy some!

Once the solid rocket boosters leave the space shuttle, they are pretty much forgotten about by most people. Until now. flickr user nasa1fan has posted a bunch of photos of the solid rocket boosters during their recovery at sea. Very cool lookin’.

Podcast: Simo-Slacker Interviews Pt. II

By Michael on April 15, 2009 at 11:47 pm | In Audio Podcasts | 1 Comment

Wild Stars

In Part I we presented 2 interviews from Mike Simonsen of Simostronomy (and the AAVSO) from a conference he attended recently, Wild Stars in the Old West II . Mike has blogged extensively about this.

In this episode we present 3 new interviews with professional astronomers about cataclysmic variable stars. Christopher Tout, Paula Szkody and Boris Gaensicke discuss their work and ideas from the conference. It can be heavy stuff at times but gives a fascinating insight into the world of stellar astrophysics.

Many thanks to Mike Simonsen for bringing us these interviews! He is a fun guy to talk to. We’ll be hearing more from Mike!
