Hi everyone, 

We were so excited to see many of you in April and are excited to announce we are continuing the public nights! Please join us in Pupin Hall on Friday May 2 at 7pm to learn about the post-deaths of massive stars from graduate student Shifra Mandel.

What do black holes, white dwarfs, and neutron stars have in common?  They are all dead inside, formed out of the collapsed remnants of stars that were once home to prolific nuclear fusion factories.  They also exert extreme gravitational forces on their surroundings.  And when they retain (or obtain) a living companion star, sparks – and X-rays – can fly!  We’ll examine how these cannibalistic “zombie” stars power some of the most energetic phenomena observed in our universe.

Unfortunately, Columbia's campus is still closed to non-affiliates, so you need to register in order to join this event. 

To register, fill out this form for everyone in your party by midnight APRIL 30: https://forms.gle/CApCEH1QNWyaLYSAA

Each adult must register with a unique email address. We cannot accept repeated email addresses. After you register, Columbia will email you a QR code during the week of the event to the email you put on the form. The QR code will come from  caladmi...@columbia.edu with "CU Guest Access" as the sender. You must bring the QR code and an ID to get on campus at the 116th and Broadway gates.

Minors (under age 18) must also register, but they will not be asked to provide an email address. They will not be emailed a QR code or need to show an ID. 

If you do not fill out the form by April 30 or bring the QR code and your ID, we cannot get you into the event. We apologize for the inconvenience of the logistics. Please let us know if you have any questions.

We'll start the evening at 7pm with some astronomy trivia, followed by Shifra’s talk and Q&A. From 8:10-9:10pm, we will be outside stargazing on Low Plaza (weather permitting). 

The main event will take place in Pupin Hall 301. Signs will be posted to direct you to the lecture hall, and general directions to Columbia and Pupin Hall can be found here. Outdoor observing/stargazing will take place on Low Plaza, in front of Low Library; we will walk down to Low Plaza as a group following the lecture and Q&A. Telescopes and binoculars will be provided by Columbia Astronomy (but you are absolutely welcome to bring your own observing equipment).

This event is free and open to all -- stay only as long as you want. We're looking forward to seeing you in Pupin Hall!

Very best,

Columbia Astronomy Public Outreach

Just a reminder that we are having another Astronomy Public Night in one week! Keep your fingers crossed for good weather for observing after the talk.

If you have already registered, thank you so much! You should have just received a QR code from  <caladmi...@columbia.edu>. If you haven't registered yet but would like to attend and don't have a Columbia ID, you can do so until April 30 midnight, and you will receive your QR code next week. We will send one more reminder on the final day to register.

Thanks to everyone who has already registered! If you have registered and are not a minor, you should have received a QR from <caladmi...@columbia.edu> by now.

This is a reminder to register by midnight tonight if you have not already done so and plan to attend. You must register to gain access to the event. Below are a couple of things to keep in mind:
  • Minors do not need an email or an ID when registering. Their names will be added to a list, but they will not receive a QR code
  • Everyone else must have a QR code and an ID to enter campus. The QR code will be emailed to the email you put on the registration form
  • There cannot be repeated emails. Each adult must be registered with a unique email
Thank you all so much for your patience with the complex registration process. We're excited to see you Friday! If you can't join us, we will stream the talk on our Youtube channel: https://www.youtube.com/@columbia-astro-outreach

For those of you joining for observing, we are in front of Pupin, not on Low Plaza. Sorry for the change in location!
