Discover what’s new in the universe from the people making it happen!

Join a local astronomy expert in the Alden Planetarium and dive into the latest discoveries in the grandest science of all. Every month, a researcher from the Worcester area will come to the EcoTarium to discuss their work - everything from Martian water to astrophotography and from community science to space telescopes. Come back each month to learn more about our cosmic hometown!
