Professional astronomy has long since moved past the telescopes of Kepler and Galileo. How do the massive astronomical instruments you see in the news work, and how are they designed? To find out more, join us online on Wednesday, September 30 at 6:00pm. Prof. Abigail T. Crites will be taking us step-by-step as she deconstructs the astrophysicists' toolbox! As always, everyone is welcome!

It's a great week for some planetary observing! Mars is at opposition, which means it'll be big and bright and beautiful as we come between it and the Sun.

In elegant and humorous prose which makes her book highly engaging and readable, theoretical astrophysicist, Dr Katie Mack, makes clear almost immediately where her story will end: with the end. Of Everything. It’s not a plot twist that’s wholly unexpected, but there’s more: fire. That’s going to be the element that is finally our grand undoing (the “we” is rhetorical - human life will long have been extinguished), white hot fire from the swollen sun like nothing we can imagine.

Today’s the day! Mars is at its closest approach to Earth, making it the biggest and brightest it will be for another 15 years!

Mars is at opposition tonight! That means it's on the exact opposite side of the sky to the Sun, and we get to see it all night long. Join us tonight for live views of Mars and the other fall planets through our members' telescopes. We'll have a guest expert on Mars and will be spending lots of time answering your pressing questions about the red planet!

We're catching a few last targets and going over some previous ones that you may have missed from earlier in this series. We're going to do our best to see the Zodiacal Light this week too.
