This Blog's History
Starting several years ago, every Friday I link back to a previous post I wrote. Why? I may be biased, but I think there's quite a bit of good, exciting science I post on this blog, and I like to revisit these old posts. Plus it is a way for new readers to see many of the cool science experiments I've done with my kids in the past without reading the blog from day one, which was over 1,000 posts ago!
What is a quasar?
Quasars are cool sounding, but what are they? Simply put, they are very active galaxies. They send off jets of energy and we observe them as very energetic galaxies we call quasars. For more details on quasars, head to the original post on quasars I wrote a few weeks ago.
