Owen Brazell - Globular Clusters
A talk given by Owen Brazell to Herefordshire Astronomical Society on the
5th December 2024.
Owen is President, Director of the Galaxies Section, Joint Meetings Organiser and DSO Editor for The Webb Society. He has previously been the Assistant Director of the British Astronomical Association's Deep Sky Section and is a columnist for Astronomy Now.
For our December talk, Owen delves into Globular Clusters - what are they, who discovered them, where do they come from, how do you describe them, what different types of star groupings are there, are there any in other galaxies, and how can you find and observe them.

    Thank you very much for this. I have 3 questions: 1) if neutrons and protons are 2 different groups of different quarks, how did one switch into another? 2) why any other combinations of quarks happened to be impossible? 3) what does it mean that gravitational energy is negative that reduces total amount of energy required?

      FYI for others interested - Steve gave the following answers for @theExai: 1) if neutrons and protons are 2 different groups of different quarks, how did one switch into another? Quarks/antiquarks make energy; energy makes quarks/antiquarks; back-and-forth, back-and-forth... Hence the quarks labelled in one instant as 'these three are a proton' will change from one instant to the next. A fraction of a second later, the three quarks could be different and labelled 'a neutron'. 2) why any other combinations of quarks happened to be impossible? They aren't - dozens of combinations of quarks are possible. Protons and neutrons are the lightest and all the rest are heavier and unstable. Protons and neutrons are the interesting ones because, along with electrons, they make up all the atoms in the observable universe. (See Wiki article en.wikipedia.org/wiki/List_of_baryons) 3) what does it mean that gravitational energy is negative so that reduces total amount of energy required to be borrowed? Imagine two static objects with zero energy separated by a very large distance. If they fall towards each other due to gravitational attraction then they will gain kinetic energy (hence KE is positive) and lose gravitational energy (hence GE is negative). The sum remains zero. (See Wiki article en.wikipedia.org/wiki/Negative_energy) 4) if due to some quantum process relatively low amount of energy was enough to start the universe, because it was separated into high negative and high positive energy, might the same happen again or in some other place? "In some other place" or "again" implies that you mean another Big Bang inside our own space and time. Hypothetically, if another Big Bang occurs then it will create its own space and time, so we would not be aware of it. It might create matter and light but these would only exist in their own dimensions, not in ours. Some speculate that this is happening, but as we will never be able to observe it the speculation is somewhat moot.

    If the images were fake it would be more sensible to put a load of stars in the background :) why would they introduce something that could be seen as unusual. Most of the conspiracy theories are due to lack of understanding of basic principles ie I don't understand it so it must be fake.

    The problem with the AGC is not about power but about purpose. The AGC is documented as having 8 I/O instructions, three are for output, namely WOR,WAND, and WRITE. It is further stated that the RCS thrusters are controlled by and only by writing to the the two dedicated channels, ie. 5 & 6. If anyone takes the time to examine the program which is supposed to control the ascent from the moon's surface to lunar orbit. they will find that the program does not issue such WRITES ! Aside from doing some calculations and flashing numbers on a display, it performs the work of a simulator ?

    Hi Gerard, Yes, very interesting & enjoyable. Do you know what the name of his Brewery in Liverpool was? The 'Discoveries' interested me - the 6th star of the Trapezium (M42) Orion in 1842. The internet seems to have this down as John Herschel's discovey?? It will be very interesting if the proposed NASA Discovery Program ‘Trident’ mission, to revisit Triton goes ahead next year also! Many thanks!

      Hello Rob, In 1840 Mr. Lassell erected an observatory at his residence near Liverpool, happily named Starfield, in which the 9-inch Newtonian was mounted. With it he diligently observed, among other things detecting, without knowledge of its existence, the sixth star in the trapezium of Orion. I may have to correct the powerpoint, as 6th Star had been seen before. He had several partners while he was a brewer in Liverpool, but most of his years as a brewer in Liverpool he traded on his own. However when the brewery moved to North Wales, his son, also William took over the running of the business, and was trading as Lassell & Sharman. The Sharman family were connected to the Lassell's by Marriage. I do hope the proposed spacecraft to orbit the Neptune & Triton system is a reality very soon. I hope there is a reference to Lassell on board.
