Messier 94 – the Cat’s Eye Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the “Cat’s Eye” spiral galaxy known as Messier 94!

Measuring 50,000 light-years in diameter, this galaxy can be spotted with binoculars on a clear night – but only as a small patch of light. However, even with small telescopes, this object is discernible as a galaxy.
