FAQ
What is the Messier 102 Spindle Galaxy?
The Messier 102 Spindle Galaxy, also referred to as M102, is a celestial body whose exact identity has been the subject of debate among astronomers. It has been proposed as both a duplicate observation of Messier 101 and identified as NGC 5866, also known as the Spindle Galaxy, which NASA supports as the probable candidate.
Why is the Messier Catalogue significant for space exploration?
The Messier Catalogue, compiled by Charles Messier and Pierre Méchain between 1771 and 1781, is significant because it was intended to help comet hunters distinguish between permanent astronomical objects and comets. This helped advance the field of astronomy by cataloging deep space objects that are still studied today for space exploration and telescope observations.
How did Pierre Méchain contribute to the observation of Messier 102?
Pierre Méchain was originally credited with discovering M102, which he reported in 1781 and Charles Messier added to his catalogue. However, Méchain later rescinded his claim, suggesting the object he observed might have been a repeated observation of Messier 101 (the Pinwheel Galaxy), creating confusion over the true identity of M102.
What is NASA’s stance on the identity of the Spindle Galaxy?
NASA endorses the galaxy known as NGC 5866, or the Spindle Galaxy, as the most likely candidate to be the true M102. This follows historical evidence and the analysis of its properties as a lenticular galaxy, resolving at least part of the historical ambiguity surrounding M102.
What equipment is necessary to observe the Messier 102 Spindle Galaxy?
To observe the M102 Spindle Galaxy, minimal visibility can be achieved through binoculars, but small telescopes are recommended for better clarity.
