Sept 2018: The variable Hubble Nebula – Dr John Lightfoot
September 7 @ 7:30 pm - 9:30 pm
Talk by Dr John Lightfoot of the Royal Observatory Edinburgh
NGC 2261 (also known as Hubble’s Variable Nebula or Caldwell 46) is a variable nebula located in the constellation Monoceros. The nebula is illuminated by the star R Monocerotis (R Mon), which is not directly visible itself.
The star R Monocerotis has lit up a nearby cloud of gas and dust, but the shape and brightness slowly changes visible even in small telescopes over weeks and months, and the nebula looks like a small comet.
