There are three main types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. The Milky Way is a spiral galaxy containing thousands of stars and solar systems. Irregular galaxies have no defined shape and make up about one fourth of all galaxies, containing abundant gas that forms stars. Elliptical galaxies appear spherical or oval-shaped and are classified on a scale from E0 to E7 based on their circularity. Spiral galaxies can be either normal or barred, and both types have a similar structure.

A talk I gave on Secular (Slow) Processes and Galaxy Evolution given at the Evolutionary Paths in Galaxy Evolution (or "Galaxy Zoo") conference held in Sydney, Sept 2013. (http://www.atnf.csiro.au/research/conferences/2013/gzo/)
In this guide, we explore the fascinating world of galaxies, those vast cosmic structures made up of billions of stars. We provide a deeper understanding of the different types of galaxies and the processes that shape their existence.
The journey begins with an introduction, setting the stage for our exploration. We then dive into the colossal islands of stars, discovering the mind-boggling scale of these galactic entities. From there, we delve into the intricate details of billions of stars, uncovering the magnitude and diversity within these cosmic neighborhoods.
We focus on spiral galaxies, investigating their graceful arms and mesmerizing beauty. We learn about their distinct features, such as the central bulge and spiral arms, and explore the different subtypes.
In contrast, we encounter elliptical galaxies, with their smooth and elongated shapes. We explore their origins and the processes that lead to their formation.
We also explore irregular galaxies, with their irregular shapes and diverse compositions. We examine their origins and the forces that contribute to their chaotic nature.
Supermassive black holes, lurking at the hearts of galaxies, are an essential part of the discussion. We delve into their formation, growth, and influence on galactic evolution.
As we progress further, we unravel the cosmic evolution of galaxies and explore the mechanisms that drive their formation and transformation over time.
Galaxy classification takes center stage as we examine different systems used by astronomers. We explore the Hubble sequence and its significance in understanding the diverse array of galactic structures.
We delve deeper into the classification of spiral galaxies, exploring their subtypes like barred spirals and their unique features.
Elliptical galaxies also receive a closer look as we investigate their classification system and the factors contributing to their diverse range of shapes and sizes.
We witness cosmic collisions between galaxies and explore the remarkable transformations that occur as a result, providing insights into galactic evolution.
Active galactic nuclei offer a glimpse into some of the most energetic phenomena in the universe. We examine the powerful forces at play within these galactic powerhouses and explore the supermassive black holes at their cores.
In conclusion, this comprehensive guide aims to provide a deeper understanding of galaxies, those awe-inspiring structures that have captivated humanity for centuries. Whether you are an amateur stargazer or a seasoned astronomer, we hope this resource will ignite your curiosity and inspire you to continue exploring the wonders of our vast universe.

Chapter 8
Origin of the Solar System and Extrasolar Planets
*
The solar system is our home in the universe. As humans are an intelligent species, we have the right and the responsibility to wonder what we are. Our kind has inhabited this solar system for at least a million years. However, only within the last hundred years have we begun to understand what a solar system is.
*
You are linked through a great chain of origins that leads backward through time to the first instant when the universe began 13.7 billion years ago.The gradual discovery of the links in that chain is one of the most exciting adventures of the human intellect.
The Great Chain of Origins
*
Earlier, you have studied some of that story:Origin of the universe in the big bangFormation of galaxiesOrigin of starsProduction of the chemical elementsHere, you will explore further and consider the origin of planets.
The Great Chain of Origins
*
By the time the universe was three minutes old, the protons, neutrons, and electrons in your body had come into existence. You are made of very old matter.
The History of the Atoms in Your Body
*
Although those particles formed quickly, they were not linked together to form the atoms that are common today.Most of the matter was hydrogen and about
25 percent was helium. Very few of the heavier atoms were made in
the big bang.
The History of the Atoms in Your Body
*
Although your body does not contain helium, it does contain many of those ancient hydrogen atoms that have remained unchanged since the universe began.
The History of the Atoms in Your Body
*
During the first few hundred million years after the big bang, matter collected to form galaxies containing billions of stars. You have learned how nuclear reactions inside stars combine low-mass atoms, su ...

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
