This course covers the fundamentals of astrodynamics, focusing on the two-body orbital initial-value and boundary-value problems with applications to space vehicle navigation and guidance for lunar and planetary missions, including both powered flight and midcourse maneuvers. Other topics include celestial mechanics, Kepler's problem, Lambert's problem, orbit determination, multi-body methods, mission planning, and recursive algorithms for space navigation. Selected applications from the Apollo, Space Shuttle, and Mars exploration programs are also discussed.

Join Prof. Chris Impey in this Astronomy for beginners course and learn about today's amazing astronomical discoveries!

The Big Bang theory has revolutionized our understanding of how the Universe was formed. It presents the scientific proof that shows how the Universe expanded from an infinitely small point around 13.7 billion years ago. In this free online course the learner will discover how scientists calculated when the Big Bang happened and how the Universe expanded after the Big Bang. The formation of the first atoms is discussed and how they are responsible for the cosmic background radiation that is found throughout the Universe. This free online course will be of great interest to students of astronomy and physics and to all learners who would like to learn more about the Big Bang theory and what it has to say about the formation of the Universe. <br />

Get a sense of the universe's enormity and discover the infinitesimal portion of history occupied by human existence with this astronomy course. Instructors show you how scientists go about studying such a vast expanse of time and space by explaining topics like wave-particle duality and spectra sequence. They can also help you take on an in-depth examination of astronomical objects that include protostellar disks, black holes, neutron stars, the Jovian planets and more with lessons on the following topics:

This course focuses on three particularly interesting areas of astronomy that are advancing very rapidly: Extra-Solar Pl

Learn the VCE Physics Astronomy course through instruction, simulations and your own observations of the night sky.

Explore the evolution of the universe, the future of astronomy & the role technology plays in new discoveries.

This course is designed for anyone who is interested in learning more about modern astronomy. We will help you get up to date on the most recent astronomical discoveries while also providing support at an introductory level for those who have no background in science.

This course provides a graduate-level introduction to stellar astrophysics. It covers a variety of topics, ranging from stellar structure and evolution to galactic dynamics and dark matter.

This is the second course in a two-semester sequence on astrophysics. Topics include galactic dynamics, groups and clusters on galaxies, phenomenological cosmology, Newtonian cosmology, Roberston-Walker models, and galaxy formation.

This course covers cosmology – the study of our entire universe. Where did the universe come from? How will it end? What is the nature of space and time?  For the first time in human history, we can give precise, reliable answers to many cosmological questions, thanks to a spectacular series of recent breakthroughs.  But many of the most fundamental mysteries remain unsolved. In this course we will cover the latest advances and the unsolved mysteries. We will explain the recent observations, and with the help of guest speakers Lawrence Krauss and Brian Cox, we will explore the theories behind modern cosmology.

This course is designed for people who would like to get a deeper understanding of astronomy than that offered by popular science articles and shows. You will need reasonable high-school level Maths and Physics to get the most out of this course.

This is one of four ANUx courses which together make up the Australian National University's first year astrophysics program.

The discovery of exoplanets is one of the greatest revolutions in modern astrophysics. Twenty years ago, we had no idea whether any of the countless stars out there beyond our solar system had planets or not.

Today, things are totally different. Over 1,000 planetary systems have been discovered. The universe is teeming with planets. And what strange planets they are - hot Jupiter-like planets skimming the surfaces of their stars, cold and lonely free-floating planets far from any star, planets made of diamond, planets with rain made of glass, super-Earths and even planets orbiting neutron stars. In this course, we’ll bring you up-to-date with the latest research on exoplanets, and how this research has revolutionised our understanding of the formation of solar systems like our own.

This course is designed for people who would like to get a deeper understanding of these mysteries than that offered by popular science articles and shows. You will need reasonable high-school level mathematics and physics to get the most out of this course.

This is the second of four ANUx courses which together make up the Australian National University's first year astrophysics program. It follows on from the introductory course on the Greatest Unsolved Mysteries of the Universe, and is followed by courses on the violent universe and on cosmology. These courses compromise the Astrophysics XSeries. Learn more about the XSeries program and register for all the courses in the series today!

Interested in exploring the deadliest and most mysterious parts of our universe? Or, investigating black holes, which warp the very fabric of space-time around them?

We will look at what we know about these objects, and also at the many unsolved mysteries that surround them. We will also study white-dwarf stars and neutron stars, where the mind-bending laws of quantum mechanics collide with relativity. And, examine dwarf novae, classical novae, supernovae and even hypernovae: the most violent explosions in the cosmos.

This is the third of four ANUx courses which together make up the Australian National University's first year astrophysics program. It follows on from a course on the Greatest Unsolved Mysteries of the Universe, and a course on exoplanets. It is not necessary to have done the previous courses first: all necessary background material is repeated here. It is followed by a course on cosmology.

How astronomy really works - an overview of the technology that astronomers use to collect and measure light from the universe, and how it is used in practice to make scientific discoveries.

This course covers everything a developer needs to know to asynchronously send and receive data in their web applications. You'll dive into how asynchronous requests work by using the XHR object to create and send asynchronous requests for image and news article data. Then, you'll see how you can perform async requests more easily using third-party libraries and APIs like jQuery's Ajax and the Fetch API.

Want to supercharge your JavaScript? Asynchronous programming keeps web applications responsive by allowing multiple tasks to be processed at the same time.

This computer science course will cover the latest asynchronous features in JavaScript, such as Promises and Generators. By the end of this course, you should be able to make asynchronous network requests and write maintainable asynchronous code in JavaScript.

This course focuses on novels and films from the last twenty-five years (nominally 1985–2010) marked by their relationship to extreme violence and transgression. Our texts will focus on serial killers, torture, rape, and brutality, but they also explore notions of American history, gender and sexuality, and reality television—sometimes, they delve into love or time or the redemptive role of art in late modernity. Our works are a motley assortment, with origins in the U.S., France, Spain, Belgium, Austria, Japan and South Korea. The broad global era marked by this period is one of acceleration, fragmentation, and late capitalism; however, we will also consider national specificities of violent representation, including particulars like the history of racism in the United States, the role of politeness in bourgeois Austrian culture, and the effect of Japanese manga on vividly graphic contemporary Asian cinema.

We will explore the politics and aesthetics of the extreme; affective questions about sensation, fear, disgust, and shock; and problems of torture, pain, and the unrepresentable. We will ask whether these texts help us understand violence, or whether they frame violence as something that resists comprehension; we will consider whether form mitigates or colludes with violence. Finally, we will continually press on the central term in the title of this course: what, specifically, is violence? (Can we only speak of plural "violences"?) Is violence the same as force? Do we know violence when we see it? Is it something knowable or does it resist or even destroy knowledge? Is violence a matter for a text's content—who does what, how, and to whom—or is it a problem of form: shock, boredom, repetition, indeterminacy, blankness? Can we speak of an aesthetic of violence? A politics or ethics of violence? Note the question that titles our last week: Is it the case that we are what we see? If so, what does our obsession with ultraviolence mean, and how does contemporary representation turn an accusing gaze back at us?
