de-trend setter (or, transit photometry from the MSGC-observatory)
In which I observe an exoplanet transit, and explain how I fit a model to my observations. For a brief intro to, and some artsy pictures of, the Maryland Space Grant Observatory I’ve been starting to use, visit this previous post. What if I told you I observed a planet, orbiting a star hundreds of […]

good morning baltimore! (or, grism spectroscopy from the MSGC-observatory)
If there’s one thing I know about myself, its that if there’s a telescope in my vicinity I am going to try to drive it. I recently started grad school at Johns Hopkins University, whose Physics and Astronomy Department building is host to the Maryland Space Grant Observatory (pictured below). I’ve made some awesome friends […]

making stars (feat. ic 5146: the cocoon nebula)
when molecular clouds – large clumps of gas and dust within galaxies – become unable to support their own weight they collapse inwards into a cascading series of overdensities and clumps which then become stars. even if they can support themselves, collisions between clouds, supernovae, or other dramatic events can cause dynamical disruptions in molecular […]

make your own color magnitude diagram
Luritja aboriginal astronomers have a classification system for by-eye observation of stars: Tjilkera (white) stars, Tataka Tjilkera (red/white), Tataka (red) and Tataka Indora (very red) [1, 2]. Astronomers today, thanks to Williamina Flemming and Annie Jump Cannon (among other Harvard Computers), use a rather opaque system of stellar classification called the Harvard spectral classification: OBAFGKM(LTY), […]
