Overview

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.

Syllabus

Astronomy: Exploring Time and Space
-Here you can find all of the introductory information, course syllabus, and current announcements.

Science and History
-Science combines logic and evidence to increase our understanding of the natural world, including remote and inaccessible regions of space and time.

The Night Sky
-Astronomy is the oldest science, and its history shows a growing realization of our insignificant status in a vast and ancient universe.

The Tools of Astronomy
-A continuing revolution in telescope design and construction is giving astronomers an unprecedented set of tools for exploring the universe.

Matter and Radiation
-Astronomers harvest information across the electromagnetic spectrum, using spectra to measure the composition of distant objects and diagnose extreme physical conditions.

The Solar System
-Space probes have visited most planets in the Solar System, and orbiters and rovers are homing in on the habitability of Mars. Space exploration is entering an entrepreneurial phase that might let us venture beyond the Solar System.

Exoplanets
-In the last few years, thousands of extrasolar planets have been discovered, including some that are Earth-like and possibly habitable.

Star Birth and Death
-Stars are the crucibles of heavy element creation, and the chaotic regions of their birth are being understood though long wavelength observations. Gravity is the ultimate victor in the life story of any star, leaving behind the exotic end states of white dwarfs, neutron stars, and black holes.

Galaxies
-The architecture of the Milky Way galaxy is that of a disk, a bulge, and a halo, with the entire assemblage bound by enigmatic dark matter. Every galaxy contains a supermassive black hole, and entire population of galaxies is sculpted by gravity into subtle structures on large scales.

Cosmology
-The expanding universe points back to an extraordinary state of extremely high density and temperature called the big bang.

Life in the Universe
-The Earth gives us a ringside seat on the physical, chemical, geological, and biological evolution of a dynamic terrestrial planet. The abundance of terrestrial planets in remote solar systems motivates the search for life and technology elsewhere in the universe.

1. origin of universe.

2. origin of life/origin of humans.

There no more great questions in the universe than these.

Astronomy can now offer questions on the origin of the universe.

Dr. Johanson at ASU is offering class on human origin on Edx.

University of Arizona. /Arizona State University are all offering free courses on line for free for all.

1. Origin of universe. 2. Origin of life /origin of humans.

This is is great class. this is great subject to study. professor know a lot.

All people with internet connection should take this class. for free.

What is better than free. Free class to know the origin of the universe.

This course is a very wide outlook of physics and astronomy . I use it frequently as an introduction to choose other MOOCs on planets or astronomy . Picking one subject after another , Pr Impey introduce cosmology or exoplanets or robotic missions , particles , telescopes etc, etc ... Very informative at a basic level . Perfect for a start .

It is the best course I've ever had online. Very nice videos, with animations and real images, a lot of extra material to read; of course it is also demanding, but it is really worth it if you are passionate about astronomy.

The course is lengthy and time consuming for the ones who have no backgroung in science, but for the ones who have an interest in astronomy, "IT'S WORTH TAKING IT" .

A good introductory course. Can be taken by undergrads who wish to understand the field of Astronomy in fair detail.

This is a great overview of modern astronomy, astrophysics and cosmology, and even astrobiology. It features lectures not only on philosophy of science and history of space missions, but it gves a nice commentary on the current technological state as well. There are lectures on Solar System, where you can find out about planets and moons, and basic astrobiological terminology, which is then further investigated in later lectures. There is also a lecture on telescopes, which is really useful for techies, and the techniques for finding exoplanets are discussed as well. All in all, the most comprehensive introduction to astronomy online, and the most fun one. It's perfect for beginners, and it's great for experts trying to find better teaching methods. The class features lots of excerpts - educational and fun ones - which make the learning process amazing. Every recommendation!

The course itself is okay but it attracted some real fruitcakes. Its the usual Atheist versus Christian garbage I've seen this on other Coursera courses, but this one was the worst since even complaints to Coursera came to nothing, and insulting threads were left open. I have no interest in this discussion, but it is hard to ignore when the motivated people keep getting their threads and comments high on the forum boards. I am sick of this Christian bashing nonsense. It is completely disrespectful. One guy in particular just kept on posting his very opinionated hate speech aimed at Christians, and nothing was done about him. Anyone who commented on his intolerance was attacked. Not worth it, unless they can put this in order and actually close down inappropriate threads and comments aimed at hurting a portion of the student population.
