Normal matter - the stars, planets, gas, dust, atoms, molecules that we can see with our telescopes - makes up only about 5% of the universe. Curious about the other 95%? Associate Professor Nick Battaglia and graduate student Raagini Patki will share what scientists know about dark matter and dark energy, and what they hope to discover. Cornell Friends of Astronomy will host a free virtual talk on March 25 at 8:00 p.m. EST. For the Zoom link, contact friendsofastronomy@cornell.edu.
