The Newsletter on Astronomy Education for K-12, College, and even Home Schooling science teachers.

The Classroom Astronomer Newsletter  (TCA, or TCAN) was a twice-monthly email newsletter, or as we prefer to call it, an Inbox Magazine, on Substack that covered many of the same topics as the 2009-2015 magazine, and debuted in May 2021. 

The newsletter contained:

  1. Articles on useful educational software.
  2. Regular columns like Astronomical Teachniques–tips and methods to teach specific topics, Connections to the Sky–external sources of resources or programs to help you with your instruction–and The RAP Sheet–items found in scholarly research that you can use now
  3. Occasional short term columns that have been, or are running, that include a look at the astronomy standards in the NGSS–Next Generation Science Standards–and Astronomy Remotely, Internet observatories you can use.
  4. And sometimes other things!

Designed for use for all levels of astronomy educators, including the pandemically virtual home teachers and home schoolers, and anyone who wants more than just a “Wow, what’s up in the sky?” news briefing. Many items come from the most recent astronomy and astronomy education world conferences! Written by longtime astronomer, journalist and educator Dr. Larry Krumenaker. 


Subscribe by the month or by the year. Free Subscribers get one issue per month, usually the one with Sky Lessons–using current sky events to teach an astronomical concept, Connections–resources, and Astronomical Teachniques relevant to general astronomy education, public outreach and K-12 schools. Premium paid subscribers get this issue and 1-2 other issues each month on conference proceedings, RAP Sheet summaries of useful articles from over 30 scholarly journals monitored, and Teachniques, Connections and other materials for public outreach, planetariums, museums and university level astronomy education. It pays to go premium!

Here is a sample of a Full Issue!: Issue 13

Here is a special FREE issue, TCA 25, on how to measure the Moon’s size and distance using the passage of the Moon through the Earth’s shadow on May 15-16, 2022, and a tennis ball (or other small sphere)!

On this website you’ll find an index to topics discussed, and you can find the issues’ Tables of Contents. From Issue 9, the Archive on Substack is available only to Full Issue subscribers. When you subscribe, your first issue is free before you are charged.

It is intended to upload the issues here in the future after Dr. K’s medical leave ends.
