Variable Nebula

Guest Speaker

Thursday, 14th September 2023 (19:45 - 22:00)

Venue: Hybrid

Variable nebulae are nebulae that exhibit changes in their appearance, usually due to the variability of the young stars within them. Young Stellar Objects (YSOs) are protostars or very young stars that are still in the process of contracting and forming. These stars are often found in variable nebulae, and their variability is thought to be caused by changes in the accretion of material onto the star or changes in the surrounding disk of gas and dust.

Speaker: Nick Hewitt

Nick has long been dedicated to amateur astronomy. Although deep sky astronomy has always been his area of expertise (he served as director of the BAA's deep sky section from 1992 to 2003), he also enjoys all facets of astronomy. He is also a passionate eclipse chaser and Mars imager (when not too low!). He initially joined the BAA in 1967 and remained a member until 1974, pausing for a time during which he indulged in wine, women, and music before re-joining in 1983. He has valued the companionship and support of many outstanding amateur and professional astronomers. He recently left the practice of general medicine and wants to increase his productivity regarding observations and imaging.
