Learn about heavens from scientists who study them

A monthly chance to learn from scientists who study the heavens at the Space Telescope Science Institute takes place tomorrow. The institute, on the campus of Johns Hopkins University at 3700 San Martin Drive, is hosting its regular lecture event at 8 p.m. Scientist Marcel Haas will give a lecture titled “Growing Galaxies in Supercomputers.” If you can’t make it, the Bloomberg telescope is also open to the public Friday evenings, weather permitting.
