Astrophiz 145: Dr Ian Musgrave’s April SkyGuide

Enjoy your regular monthly treat for all naked-eye celestial observers, telescopers, and astrophotographers from Dr @IanfMusgrave, amateur astronomer, molecular pharmacologist and toxicologist.
Ian gives us the dates of the moon phases and the best times to observe planets, clusters and deep sky objects.
In Ian’s Tangent, he continues his theme to discuss the problems with our descriptions of celestial objects, in this case the way the size of these objects are compared with the size of familiar animals. eg recently an asteroid’s size was expressed as ‘the size of a giraffe’.
Not helpful, but Ian suggests an alternative.
